Mars in the 2nd house is the chart line people look up when money is on their mind. Does it mean you will earn a lot? Does it mean you will burn through it? Most guides answer in two lines and move on. We did two other things first. We counted who gets this placement among US babies. Then we read what the old books say about it, word for word.
The count held a surprise. Your birth year can nearly double the odds. About one US baby in nine born in 2016 got Mars in the 2nd house. The year before, it was closer to one in seventeen. The reason is not only the sky. It is the hospital clock.
This guide shows the count, the method and the old debate. It makes no promise about your bank account. Astrology is not a science, and no count of charts can test an income.
The 2nd house is the sky that rises next
A birth chart splits the sky into twelve slices called houses. Each house stands for one part of life. The 2nd house stands for what you own, what you earn and what you think is worth having. We cover the room itself in our guide to the 2nd house and what it holds.
In the sky, the 2nd house is a real place. Picture the eastern horizon at the minute you were born. The strip of sky just under it is the 1st house. It will rise in the next two hours or so. The strip under that is the 2nd house. It will rise after the 1st.
So Mars in the 2nd house has a plain meaning. At your birth, Mars was below the eastern horizon. It was not the next thing to rise, but the one after that. Mars in the 1st house runs the same appetite and anger through the body and the first impression you make.
Two ways to cut the room
Chart apps do not all draw the houses the same way. Two methods lead the field in the US.
Whole sign houses are the oldest method. The sign rising in the east is your whole 1st house. The next sign is your whole 2nd house. So Mars is in your 2nd house if it sits in the sign right after your rising sign.
Placidus is the default on most US sites and apps. It cuts the sky by time, not by sign. Take the time a point needs to climb from its lowest spot under the ground up to the eastern horizon. Placidus splits that time into three equal parts, and the 2nd house is the middle part. You can see how the cuts are made in our guide to the Placidus house system.
Both methods give the 2nd house to about one chart in twelve on paper. The real share is lower, and it swings from year to year. Here is why.
How many US babies get Mars in the 2nd house
We counted every birth minute, day by day, across 303 places that cover the US population. Then we weighted each minute by how many US babies are really born at that hour. The hour data comes from the CDC natality file 2024, the US birth record for that year. It holds 3,638,436 births, and only 666 lack a time.
If babies were born evenly around the clock, Mars would sit in the 2nd house in 8.26 percent of US charts under Placidus. Under whole sign it would be 8.50 percent. Both are close to one in twelve, which is what twelve houses give by pure chance.
Real birth hours pull the figure down. With the 2024 hours, we get 7.67 percent under Placidus and 8.07 percent under whole sign. That is about one baby in thirteen under Placidus.
These figures cover 800 years of sky, from 1600 to 2400, so each sign of Mars gets its fair share of time. For readers born from 1940 to 2030, the answer is almost the same: 7.61 percent under Placidus and 8.01 percent under whole sign.
The drop from 8.26 to 7.67 percent is larger than it looks. For Jupiter in the 2nd house, real hours barely moved the total. For Mars, they cut about one chart in fourteen. The next part explains the gap.
Mars keeps close to the Sun, and that sets the hour
Mars circles the Sun on a wider track than ours. Seen from Earth, it spends most of its time on the far side of the Sun. In our count, Mars sat within 60 degrees of the Sun in 52.8 percent of US births. A planet close to the Sun rises close to dawn.
The Moon has no such tie to the Sun, so a Moon in the 2nd house can fall at any hour, set by its phase.
That fixes the hour of the 2nd house. When Mars sits near the Sun, it rises around sunrise. So it passes through the 2nd house a few hours before that, from about 3 a.m. to 6 a.m. Those are the quietest hours on a maternity ward.
Here is the chance of Mars in the 2nd house for each hour of the clock, under Placidus. It covers all 800 years and all 303 places.
| Birth hour on the clock | Chance of Mars in the 2nd house. |
|---|---|
| Midnight to 1 a.m. | 12.0 percent, about 1 in 8. |
| 3 a.m. to 5 a.m. | 13.7 percent, about 1 in 7. |
| 8 a.m. to 9 a.m. | 10.4 percent, about 1 in 10. |
| Noon to 1 p.m. | 4.4 percent, about 1 in 23. |
| 3 p.m. to 4 p.m. | 2.9 percent, about 1 in 34. |
| 6 p.m. to 7 p.m. | 3.8 percent, about 1 in 26. |
| 9 p.m. to 10 p.m. | 7.7 percent, about 1 in 13. |
The top of the curve sits at 3 to 5 a.m. The bottom sits at 3 p.m., almost five times lower. This is the same wave as Mars in the 1st house, moved about two hours earlier. That makes sense. On its way up to the eastern horizon, a planet crosses the 2nd house about two hours before it reaches the 1st.
Now lay the hospital clock over this curve. In 2024, the 8 a.m. hour was the busiest, with 6.3 percent of all US births. The hours from 2 a.m. to 6 a.m. held only about 3 percent each. Planned cesarean births peak at 8 a.m., and induced births fill the hours from noon to 5 p.m. Most births land in the day, when the chance of Mars in the 2nd house is low. That is why real hours pull the total down.
Your birth year can nearly double the odds
Mars and the Sun go through the same dance every 26 months or so. For part of that cycle, Mars stands in the evening sky, well east of the Sun. Then it rises in the late morning, and its 2nd house hours fall right on the 8 a.m. rush. In our count, when Mars stood 60 to 150 degrees east of the Sun, about 10.3 percent of US babies got it in the Placidus 2nd house.
For the rest of the cycle, Mars sits near the Sun. Its 2nd house hours fall before dawn. When Mars stood within 30 degrees of the Sun, only 6.0 percent of US babies got it there. With births spread evenly over the day, both cases give about 8.2 percent. The gap comes from the ward, not the sky.
Because the cycle runs about two years, the odds flip from one year to the next. Here is the chance for recent US birth years, with real birth hours.
| Birth year | Placidus | Whole sign. |
|---|---|---|
| Born in 2015 | 5.8 percent | 6.4 percent. |
| Born in 2016 | 10.9 percent | 10.8 percent. |
| Born in 2017 | 5.9 percent | 6.7 percent. |
| Born in 2018 | 10.2 percent | 8.5 percent. |
| Born in 2019 | 6.2 percent | 7.0 percent. |
| Born in 2020 | 8.2 percent | 6.1 percent. |
| Born in 2021 | 6.9 percent | 7.6 percent. |
| Born in 2022 | 7.0 percent | 5.8 percent. |
| Born in 2023 | 7.4 percent | 8.8 percent. |
| Born in 2024 | 6.4 percent | 6.2 percent. |
| Born in 2025 | 8.1 percent | 10.3 percent. |
| Born in 2026 | 6.2 percent | 6.2 percent. |
A baby born in 2016 was close to twice as likely to get Mars in the 2nd house as a baby born in 2015. Under Placidus, the best years from 1940 to 2030 reach about 10.9 percent, as in 1969, 1984, 2001 and 2016. The worst fall near 5.8 percent, as in 1968, 1983, 2000 and 2015. Under whole sign, the range runs from 5.8 to 12.1 percent.
So for Mars, the hour matters more than the sign. Our Jupiter count found the reverse for that planet, and both results hold. Jupiter sits in one sign for a year, so its sign sets the tone. Mars changes sign about every six or seven weeks, unless it turns back. Its place next to the Sun sets the hour.
Mars’s sign still moves the odds
The sign of Mars matters too, for a reason that has nothing to do with hospitals. The zodiac is the band of sky the planets move along. It is tilted against our horizon, so the twelve signs do not rise at the same speed. In New York, Aries and Pisces rise in about 1 hour and 11 minutes each. Leo, Virgo, Libra and Scorpio take about 2 hours and 31 minutes.
Under whole sign, Mars in Aries lands in your 2nd house only if Pisces was rising. Pisces rises fast, so few birth minutes give that chart. Mars in Virgo needs Leo rising, and Leo rises slowly. Placidus follows a related rule. A planet far south of the sky’s equator, in Sagittarius or Capricorn, spends more of each day below the horizon, so its 2nd house slice is long.
Here is the chance of Mars in the 2nd house for a US baby, by the sign Mars was in, with real birth hours.
| Mars’s sign | Chance under Placidus | Chance under whole sign. |
|---|---|---|
| Aries | 7.1 percent | 4.9 percent. |
| Taurus | 6.5 percent | 5.0 percent. |
| Gemini | 6.2 percent | 5.9 percent. |
| Cancer | 6.2 percent | 7.6 percent. |
| Leo | 6.7 percent | 9.3 percent. |
| Virgo | 7.5 percent | 9.9 percent. |
| Libra | 8.3 percent | 9.8 percent. |
| Scorpio | 9.1 percent | 9.9 percent. |
| Sagittarius | 9.5 percent | 9.9 percent. |
| Capricorn | 9.2 percent | 9.2 percent. |
| Aquarius | 8.6 percent | 7.6 percent. |
| Pisces | 7.9 percent | 5.9 percent. |
Under whole sign, Mars in Virgo, Scorpio or Sagittarius is about twice as likely to land in the 2nd house as Mars in Aries. Under Placidus, Mars in Sagittarius is about 1.5 times as likely as Mars in Gemini or Cancer.
There is a second layer. Mars does not spend equal time in each sign. Over 1600 to 2400, it spends 10.07 percent of the time in Virgo, 10.00 percent in Leo and 9.58 percent in Libra. It spends only 6.82 percent in Pisces. Put the two layers together, and under whole sign, 36 percent of all Mars-in-the-2nd charts have Mars in Leo, Virgo or Libra. Those three signs hold only 30 percent of the planet’s time. Under Placidus, the lift vanishes, since those three signs sit in the middle of the table.
Two real New York charts show the size gap. On 13 October 2020, Mars was in Aries, facing the Sun across the sky. Its whole sign 2nd house window ran from 4:13 p.m. to 5:24 p.m. local time, just 71 minutes. On 24 April 1999, Mars was in Scorpio, at the same stage of its cycle. Its window ran from 4:46 p.m. to 7:17 p.m., which is 151 minutes. Same city, same stage, and a window more than twice as long.
Strong Mars, weak Mars: which one you are likely to hold
The old writers judged a planet by the sign it sat in. Mars rules Aries and Scorpio, so it is at home there. It is exalted in Capricorn, its seat of honor. It is in exile in Taurus and Libra, the signs across from its homes. It is in its fall in Cancer.
That matters in the 2nd house, because William Lilly makes the sign part of the verdict. More on his rule below. First, the count. Among all US charts with Mars in the 2nd house, here is how the strong and weak versions split, with real birth hours.
| Version of Mars | Share under Placidus | Share under whole sign. |
|---|---|---|
| At home in Aries | 6.5 percent | 4.3 percent. |
| At home in Scorpio | 10.4 percent | 10.8 percent. |
| Exalted in Capricorn | 8.6 percent | 8.1 percent. |
| Strong, all three | 25.5 percent | 23.2 percent. |
| In exile in Taurus or Libra | 17.0 percent | 16.6 percent. |
| In its fall in Cancer | 7.6 percent | 8.9 percent. |
| Weak, all three | 24.6 percent | 25.5 percent. |
So about one Mars-in-the-2nd chart in four holds a strong Mars. About one in four holds a weak one. Half hold neither. Under whole sign, the Scorpio version outnumbers the Aries version more than two to one. That is the rising time again: Libra rises slowly, Pisces rises fast.
Mars in the 2nd house: does it bring money or cost it?
Here is the honest answer. No one can promise either. What we can do is report what the old writers said, as they said it. They were not kind to this placement, but they were not simple about it either.
Vettius Valens: the Gate of Hades
Vettius Valens wrote the Anthologies in the 2nd century. It is the largest Greek astrology text to survive. In his list of the twelve places, the 2nd place stands for life, in the sense of your living. He gives it a darker name too: the Gate of Hades.
In the chapter on that place, Valens writes that the good planets do no good there. The harsh planets, he says, make people slow and hurt, unable to wade through their lives to the end. Mars is one of the two harsh planets. Valens adds a case for Mars when it also rules the Lot of Fortune and the rising sign. Then it makes people quick to give offense and open to penalties, with their plans held up. Some are taken captive, he writes, and later freed. We quote Mark Riley’s translation.
Valens’s list for Mars itself fits the money theme. Among many things, it names the loss of goods, lawsuits, craftwork, and work with fire or iron.
Ptolemy: look at another point
Claudius Ptolemy wrote the Tetrabiblos around 150 AD. In his chapter on wealth, he does not use the 2nd house at all. He looks at the Lot of Fortune, a point worked out from the Sun, the Moon and the rising degree. The planet that rules that point shows where money comes from. Lilly sums up Ptolemy’s line on Mars in a few words: it enriches by war and the conduct of armies.
William Lilly: potent or unfortunate
William Lilly wrote Christian Astrology in London in 1647. He gives the 2nd house the estate and the movable goods. In his chapter on whether wealth will last, he gives a rule for a harsh planet in the 2nd house. Mars is one of them.
First, Lilly says, see if the planet is strong or weak. If it is potent, the estate shall continue, but with difficulty, and the native shall be subject rather to lose than lay up. If it is unfortunate, the fortune shall not continue, but come to nothing. In the same chapter, he lists Saturn, Mars or the Sun badly placed in the 2nd house as a bad sign.
Note what Lilly does not say. He does not say Mars in the 2nd house means no money. He says strong Mars keeps it, with effort. That is why the sign count above matters. One chart in four holds the strong version.
Lilly lists the trades Mars brings money through, too. They include lawsuits, soldiering, surgery, smithing and work with iron or fire. In modern words: hard, physical, risky work, or work that runs on a fight.
What that leaves you with
So the old books agree on the tone, if not the details. Money in this house comes through effort and friction. It goes out fast. Its fate depends on how strong Mars is and on the rest of the chart. None of them wrote that this one line makes a person rich or poor.
It helps to set Mars next to its neighbors. Our guide to Saturn in the 2nd house reads that placement as money that comes slowly and stays. Jupiter in the same room splits the old books between gain and loss. Mars is the fast one of the three: money won by a push, and spent by one.
Mercury, the planet of trade, keeps far closer to the Sun, and our count of Mercury in the 2nd house found it in about one US baby in sixteen, almost all born before 7 a.m.
The modern reading: earning by force of will
Modern astrologers moved the 2nd house from the purse to the inner sense of worth. In that view, Mars here is the drive to earn, to own and to prove your value by what you can do. People with it are said to go after money head-on. They start side jobs, argue for a raise and act fast when a deal shows up.
The cost is the same speed, pushed too far. Buying on impulse. Fighting over bills. Taking a risk because waiting feels like losing. That is Valens’s warning, told in new words. It is Lilly’s rule as well: rather to lose than lay up.
There is a gift in it. Mars in the 2nd house does not wait for money to arrive. It goes and gets it. For the house next door, see our piece on Mars in the third house, where the same drive moves into talk and the daily mind.
How to work with it
If you have this placement, three habits fit both the old and the new readings.
Put a wall between wanting and buying. Wait two days before any large purchase that is not a need. Mars acts fast. A short delay lets the rest of you catch up.
Keep a floor. Set a sum you never touch, and set it on a calm day. Lilly’s rule says a strong Mars keeps its gains only with effort. A floor is that effort, made into a habit.
Check the rest of the chart. Lilly never judged wealth from one planet. Look at Mars’s sign, at the ruler of your 2nd house, and at your Lot of Fortune. A strong Mars with help from those points reads very differently from a weak Mars on its own.
How to check your own chart
You need your birth time to the minute. A house shifts in about two hours, and a narrow 2nd house can pass in about one.
Cast your chart twice, once in Placidus and once in whole sign. If Mars is in the 2nd house in one and not the other, it sits near a line. Read the 1st or 3rd house page as well.
Then note the sign of Mars. Use the tables above to see whether you hold a common or a rare version, and a strong or a weak one.
How we measured it
We did not draw charts at random. We swept a regular grid of days. For the long window, we took every 23rd day from 1 January 1600 to 31 December 2399. For the reader window, we took every 3rd day from 1 January 1940 to 31 December 2030. On each day we covered all 1,440 minutes.
Places were 303 clusters built from the 2020 census centers of population of US counties, each weighted by its people. Clock time is local legal time, with daylight time in summer. For 1940 to 2030 we used each place’s real time zone history. For the long window we used today’s rules.
For each minute we worked out the house from the sky, with our own formulas. Placidus puts a point in the 2nd house when it is in the middle third of its climb from its lowest spot to the eastern horizon. Whole sign puts it there when the sign after the rising sign holds it. The place of Mars came from the Swiss Ephemeris. Each minute was then weighted by the share of US births at that minute, for that month and that day of the week, from the CDC natality file 2024.
We checked the work three ways. First, on 20,000 random charts from 1600 to 2400, our house test matched the Swiss Ephemeris house routine in every case. Second, a separate brute force run with that routine, on the 20 largest places from 1940 to 2030, gave the same shares as our method to within two hundredths of a point. Third, a second ephemeris, astronomy-engine, put Mars within 0.006 degrees of the first.
Two limits matter. The 2024 hours are one year’s pattern, applied to every year. And clock time is not sun time. Your place in your time zone, and daylight time, can shift sun time by an hour or more, and the sky follows sun time.
Questions people ask
Does Mars in the 2nd house mean I will make a lot of money?
No one can promise that. Lilly wrote that a strong harsh planet in the 2nd house keeps the estate, but with difficulty. A weak one lets it come to nothing. Astrology is not a science, and no count of charts can test an income.
How common is Mars in the 2nd house?
About one US baby in thirteen. With real US birth hours, we found 7.67 percent under Placidus and 8.07 percent under whole sign, over the years 1600 to 2400.
Why do some birth years get it more?
Mars takes about two years to go around its cycle with the Sun. In some years it sits in the evening sky, and its 2nd house hours fall on the busy morning on maternity wards. Babies born in 2016 had it 10.9 percent of the time under Placidus, and babies born in 2015 had it 5.8 percent of the time.
What time of day gives Mars in the 2nd house?
Under Placidus, the chance peaks from 3 a.m. to 5 a.m., at about one in seven. It is lowest around 3 p.m., at about one in 34.
Is Mars strong or weak in the 2nd house?
That depends on its sign. Mars is strong in Aries, Scorpio and Capricorn, and weak in Taurus, Libra and Cancer. Among US charts with Mars in the 2nd house, about one in four holds each kind.
What did Vettius Valens say about Mars in the 2nd house?
He called the 2nd place the Gate of Hades. He wrote that the harsh planets there make people slow and hurt. When Mars also rules the Lot of Fortune and the rising sign, he says it brings offense, penalties and plans held up.
Why does one app show Mars in my 2nd house and another in the 1st or 3rd?
The apps use different house systems. Whole sign uses the sign after your rising sign. Placidus cuts the sky by time. A planet near the edge can fall in different houses under each.
