Midheaven calculator · Free · No email
What do you want your work to stand for?
Your Midheaven, or MC (from the Latin Medium Coeli, “middle of the sky”), is the degree of the zodiac that was crossing the meridian, the top of the sky over your birthplace, at the minute you were born. Astrologers read it as a symbol of public direction: what you want to be seen doing and what you hope to contribute. It changes sign every couple of hours, so it needs an exact birth time.
Find your Midheaven
The Midheaven is not the Ascendant
The Ascendant (rising sign) is the degree rising on the eastern horizon. The Midheaven is the degree on the meridian, the line running through the highest part of the sky. They are two different angles of the same chart, and they are not always 90 degrees apart: the distance between them changes with your latitude and the time of day. Two people with the same rising sign can have different MC signs.
The MC is not always the 10th house cusp
In quadrant house systems such as Placidus, which Lunara’s natal chart uses, the MC is the cusp of the 10th house by definition. In the Equal house system, houses are measured in 30° steps from the Ascendant, and in Whole Sign houses each sign is one house counted from the rising sign. In both, the 10th house is set by the Ascendant, so the MC often falls in the 9th or 11th house instead. The MC sign on this page is the same whichever house system you prefer; only its house can differ.
A symbolic lens, not a job guarantee
The Midheaven is something to reflect with. It is not destiny, a personality diagnosis, a prediction of salary or status, or a promise that a particular job will work out. If a description does not fit you, set it aside. The IC is shown because it is the exact opposite point of the same axis; this page makes no claim about your family or upbringing.
Limits
This page reads the MC from the same Swiss Ephemeris calculation that produces Placidus houses. Near and inside the polar circles Placidus houses can fail to compute, so for some high-latitude birthplaces the calculator will show that the result is unavailable rather than switching to another method. Historical clock records can also be imperfect: if your recorded time is off by a few minutes, the MC degree moves with it, and near a sign boundary the sign can change.
Frequently asked questions
- What is my Midheaven sign?
- It is the zodiac sign of the degree that was crossing the meridian above your birthplace when you were born. You need your birth date, an exact birth time and your birth city to calculate it.
- Can I find my MC without a birth time?
- No. The MC moves through every sign in about a day, so without a time it could be almost any sign. This calculator will not guess or use a default time.
- Is the Midheaven the same as the 10th house?
- In Placidus and other quadrant systems the MC is the 10th house cusp. In Equal and Whole Sign houses the 10th house is counted from the Ascendant, so the MC may sit in the 9th or 11th house instead.
- What is the IC?
- The Imum Coeli, or IC, is the exact opposite point of the MC, at the bottom of the chart. Together they form the meridian axis. This page shows it for completeness and makes no claim about your family.
- Does my Midheaven tell me which career to choose?
- No. Many astrologers read the MC as a symbol of public direction and contribution, but it does not choose a job, predict income or guarantee success. Use it as a question to think with.

Method: Swiss Ephemeris, tropical zodiac, using Lunara’s natal chart calculation; the MC is read from its angles and the IC is the point exactly opposite. Degrees and minutes are rounded down. The city sets the IANA timezone for your birth date. Your birth details and chart are kept only in this page’s memory for this calculation, never in the page address or browser storage. If you open your full chart and buy a reading, the details needed to write it are stored with your order. Text written with AI assistance.
