Midheaven Calculator
Your midheaven (MC) needs your birth date, time and place: it is the point of the zodiac that was highest in the sky at the minute you were born.

Worked example
Born 5 May 1990, 15:30 in London
Midheaven in Gemini, 21°20′
Air · Mutable
- 15:30 in London on 5 May 1990 was British Summer Time (UTC+1), so the birth instant is 14:30 UTC.
- Local sidereal time at London’s longitude (0.13°W) gives a right ascension of the midheaven (RAMC) of 80.58°.
- Projecting the RAMC onto the ecliptic gives the midheaven at 81.34°: Gemini 21°20′.
- Ten minutes earlier or later would move it by about 2–3°, which is why the birth time matters.
Midheaven through one day
The midheaven across 5 May 1990 in London
Every sign takes a turn as the midheaven once a day, and the changeovers fall at different clock times in each place and season. Times are local (British Summer Time). The first and last rows can be the same sign: it carries over midnight, so the day starts and ends in it.
| Sign | From (local) | Until (local) |
|---|---|---|
| Libra | Midnight | 00:02 |
| Scorpio | 00:02 | 02:02 |
| Sagittarius | 02:02 | 04:10 |
| Capricorn | 04:10 | 06:18 |
| Aquarius | 06:18 | 08:18 |
| Pisces | 08:18 | 10:09 |
| Aries | 10:09 | 12:00 |
| Taurus | 12:00 | 14:00 |
| Gemini | 14:00 | 16:08 |
| Cancer | 16:08 | 18:16 |
| Leo | 18:16 | 20:16 |
| Virgo | 20:16 | 22:07 |

Guide
Making sense of your result
Reading your midheaven
The midheaven (MC) is the highest point of the zodiac in the sky at your birth. Traditionally it is linked with career, reputation and the direction a person is working towards, where the ascendant describes how you meet people. In many house systems the MC marks the start of the tenth house.
Midheaven or rising sign?
The two come from the same birth time and place but answer different questions. The ascendant is the point rising in the east; the midheaven is the point crossing the meridian. Get your ascendant from the rising sign calculator, or all of sun, moon and rising from the big three calculator.
If your birth time is uncertain
The midheaven moves about 1° every four minutes, so a birth time that is half an hour out can move it by 7° or 8°. Check the time against a birth certificate or hospital record if the result is close to a sign boundary. How the calculators handle an unknown birth time explains what you can still learn without one.
Time and place
Why your birth time and place matter
Why the birth time matters
The MC moves through all twelve signs in a day. Ten minutes either way moves it by about 2.5°, so a result near a sign boundary is worth checking against your recorded time.
Why the place matters
The MC depends on local sidereal time, which comes from your longitude. Latitude barely affects it, unlike the ascendant.
Method
How this calculator works
Your birth time is converted to UTC using the time zone in force at your birth place on that date. From that instant and your longitude comes local sidereal time; with your latitude and the tilt of the Earth’s axis, that gives the point of the zodiac rising in the east (the ascendant) and the point at the top of the sky (the midheaven). Both are measured in the tropical zodiac.
Questions
Midheaven questions
What is the midheaven?
The MC (medium coeli) is the point of the zodiac crossing the meridian, due south in the northern hemisphere, at the moment of birth. It is traditionally linked with career, ambition and public image.
Do I need a birth time and place?
Yes. The MC passes through all twelve signs every day, changing roughly every two hours, and depends on your longitude.
Is the midheaven the same as the 10th house cusp?
In quadrant house systems such as Placidus and Koch, yes. In whole sign and equal houses the MC can fall in the 9th, 10th or 11th house.
Why is my midheaven in a different sign from my rising sign?
They are different points. The ascendant is on the eastern horizon and the midheaven is at the top of the sky, so they are usually a few signs apart. Both depend on the same birth time and place.
Does the midheaven change sign as fast as the rising sign?
Both pass through all twelve signs every day, but the rising sign speeds up and slows down with the season and your latitude, while the midheaven keeps a steadier pace of about 1° every four minutes.
