Rising Sign Calculator
Your rising sign (ascendant) needs your birth date, time and place: it changes about every two hours, and the same moment rises differently in different cities.

Worked example
Born 5 May 1990, 15:30 in London
Virgo rising, 23°21′
Earth · 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°.
- With London’s latitude (51.51°N) and the tilt of the Earth’s axis, the point of the ecliptic rising in the east is 173.35°: Virgo 23°21′.
- Ten minutes earlier or later would move it by about 2–3°, which is why the birth time matters.
Rising sign through one day
The rising sign across 5 May 1990 in London
Every sign takes a turn as the ascendant 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) |
|---|---|---|
| Sagittarius | Midnight | 00:23 |
| Capricorn | 00:23 | 02:09 |
| Aquarius | 02:09 | 03:18 |
| Pisces | 03:18 | 04:10 |
| Aries | 04:10 | 05:02 |
| Taurus | 05:02 | 06:11 |
| Gemini | 06:11 | 07:57 |
| Cancer | 07:57 | 10:28 |

Guide
Making sense of your result
Reading your rising sign
Your rising sign is the sign on the eastern horizon at your birth, the point astrologers use to start the chart. Traditionally it is linked with first impressions, appearance and the way you approach new situations, which is why it is often called the mask or the front door of the chart. It also sets the house layout: in whole sign houses, your rising sign is the whole of the first house.
Rising, sun and moon together
Astrologers read the rising sign alongside your sun sign and moon sign. To see all three in one result, use the sun, moon and rising calculator. The point at the top of the chart comes from the same birth details: try the midheaven calculator.
If your birth time is uncertain
Birth certificates in some countries, hospital records and baby books often give the time. If you only know it roughly, run the calculator for the earliest and latest times it could be: if the rising sign is the same at both ends, you can trust it; if it changes, treat the result as a choice between candidates. How the calculators handle an unknown birth time explains what each one can still tell you.
Time and place
Why your birth time and place matter
Why the birth time matters
The Earth turns once a day, so every sign crosses the eastern horizon once a day. At mid-northern latitudes a sign takes between about one and three hours to rise: signs from Capricorn to Gemini rise quickly, Cancer to Sagittarius slowly.
Why the place matters
Rising depends on your latitude, which tilts how the zodiac meets the horizon, and on your longitude, which sets local sidereal time. Above about 66° north or south the usual formulas break down for part of the year.
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
Rising Sign questions
What is a rising sign?
Your rising sign, or ascendant, is the sign that was coming up over the eastern horizon at the minute and place you were born. It changes about every two hours, so it is the most time-sensitive part of a chart.
Can I find my rising sign without a birth time?
Not reliably. Over a single day all twelve signs rise in turn, so without a time the calculator cannot narrow it down. A birth certificate, hospital record or baby book often has the time.
Why do I need my birth place?
The ascendant depends on where you were on Earth: the same moment gives a different rising sign in London and in New York. The place also sets the time zone used to convert your birth time.
How sure can I be of my rising sign?
The maths is exact to a small fraction of a degree; the limit is your birth time. Ten minutes either way moves the ascendant by roughly 2–3°, so if your result is within a few degrees of a boundary, check the time.
Is the rising sign the same as the ascendant?
Yes. Rising sign and ascendant are two names for the same point.
Does my rising sign change over time?
No. It is fixed by the minute and place you were born. What keeps changing is the sign that is rising right now, which moves on about every two hours.
How is the rising sign different from the sun sign?
The sun sign depends on the date and stays the same for about a month, so a twelfth of the world shares it. The rising sign depends on the minute and the place, so two people with the same birthday can have different rising signs.
