What the Ascendant is
The Ascendant is the point of the zodiac that was rising over the eastern horizon of the birthplace at the minute of birth: the intersection of the horizon with the Sun’s path across the sky. The sign of this point is called the rising sign. It begins the first house of the chart, and the point opposite — the Descendant — the seventh. In astrology the Ascendant describes manner and first impression, and the Sun sign — what a person strives for.
The Sun sign is one for a month of births, while the Ascendant goes through all twelve signs in a day. That’s why it needs the minutes and the place. More in the article “The Ascendant: what it is and why people aren’t like their zodiac sign”.
How many minutes each sign rises
The signs rise unevenly. The farther north the city, the stronger the skew: in Moscow Aries rises over the horizon in 42 min, Virgo — in 3 h 1 min. That’s why the same time error weighs differently: 20 minutes is half of Aries and a ninth of Virgo.

|---|---|---|---|
| ♈︎ Aries | 42 min 2.9% | 29 min 2.1% | 1 h 5 min 4.5% |

| ♊︎ Gemini | 1 h 41 min 7.0% | 1 h 32 min 6.4% | 1 h 52 min 7.8% |
| ♋︎ Cancer | 2 h 36 min 10.9% | 2 h 45 min 11.5% | 2 h 25 min 10.1% |
| ♌︎ Leo | 3 h 12.6% | 3 h 14 min 13.5% | 2 h 39 min 11.0% |
| ♍︎ Virgo | 3 h 1 min 12.6% | 3 h 13 min 13.5% | 2 h 38 min 11.0% |
| ♎︎ Libra | 3 h 1 min 12.6% | 3 h 13 min 13.5% | 2 h 38 min 11.0% |

Minutes — how long the sign rises per day; percent — the share of the day, that is, the share of people born with this Ascendant if births were spread evenly over the hours. This is an assumption, not maternity ward statistics. The calculation uses the rising formula for the city’s latitude: a full turn of sidereal time in steps of 0.01°, an ecliptic obliquity of 23.44° — the same way as the rising minutes on the sign pages.
If you know your birth time only roughly
In the calculator choose “Roughly” and a part of the day — or “I remember more precisely, within two hours.” It will calculate the Ascendant for every minute of the birthday and show the signs that were rising in those hours. Morning in Moscow — from three to seven signs (most often three), two hours — from one to four (most often two): that’s what our calculation for every third day of 2025 showed. Then choose by the descriptions: each sign has signs that “this isn’t about you.”
The time can also be narrowed down by the dates of moves, weddings and losses — usually to a few hours, not to the minute, and with five events there’s often no reliable answer. This is birth time rectification — a separate calculation.
Why the calculation may differ from other sites
- Time zone and daylight saving time on the date of birth. We use the history of time zones for the place: in the USSR daylight saving time was used from 1981, in Russia — until 2011, “decree” time — from 1930. An hour’s error shifts the Ascendant in Moscow by 10–44° — almost half the time (47%) it’s another sign.
- City. Moscow and Nizhny Novgorod live by the same clock, but Nizhny is 6° farther east: at the same clock time the Ascendant there is 4–20° farther along the zodiac.
- Jyotish. The Vedic lagna is counted from the stars, not from the spring equinox point — it’s 23–24° earlier (Lahiri ayanamsa for those born from 1950 to 2026). The sidereal sign is in the Jyotish reading.
- Doesn’t matter: the house system. Placidus, Koch, equal houses — the Ascendant is the same; systems differ only in the other cusps.
