Gemini rising
The sign on the eastern horizon at the moment of birth: the ascendant in Western astrology, the lagna in Vedic. It changes about every two hours, so it is the placement most sensitive to the birth time, and it is the frame the whole chart is read in.
What the Western tradition says
Western astrology reads a Gemini ascendant as a person who arrives talking: the first impression is of quickness, curiosity and a mobile face, and the body tends to be light, restless and expressive in the hands. Mercury rules the chart, so the whole life is framed as an exchange of information.
The honest shadow is the same quickness from the other side: a nervousness others feel on first meeting, a talkativeness that fills silences it should have left, and a changeability that makes the first impression unreliable as a guide to the second. The tradition keeps the wit and the flutter together.
What the Vedic tradition says of the lagna
Meets things by asking. Several threads are held at once and the interest is genuine, which is not the same as the interest lasting. That is the sidereal Gemini, which is the rising sign of a different set of people from the tropical one; the section below says which.
The two-hour window
Gemini rises in about an hour and a half in Britain, still on the short side; the sign is fully risen by the time the Sun is a couple of hours above the horizon in late spring, which puts many Gemini risings in mid-morning births at that time of year.
One sign, two ascendants
If Gemini was rising in your Western chart, Taurus was probably rising in your Vedic one.
The ascendant is a degree of the zodiac, the one on the eastern horizon at the minute of birth, and the two zodiacs measure that degree from two starting points about 24.2 degrees apart. So the first 24°14′ of tropical Gemini, which is 81 per cent of the sign, is sidereal Taurus; only a birth in the last 5°46′ of the sign, the last 19 per cent of the window, keeps Gemini rising in both. That is the same shift as the sun signs, applied to the clock instead of the calendar, and it is why a Vedic astrologer and a Western one can look at one birth and name two rising signs without either being wrong.
The calculator shows both ascendants to the degree, and flags one that sits within a few degrees of a boundary, where an uncertain birth time would move it.

Questions people ask
How do I find my rising sign?
From the date, the exact time and the place of birth: the ascendant moves about a degree every four minutes, so the time matters more than for anything else in the chart. The calculator gives it in both zodiacs, and an approximate time is handled as two candidate charts rather than a guess.
Is my rising sign more important than my Sun sign?
Western astrology reads the ascendant as the frame and the Sun as the centre, and Vedic astrology reads the lagna as the first house and the Moon before the Sun. Neither tradition has a single most important placement, and a page that names one is simplifying. The free chart shows all three together.
Why does my Vedic chart give a different rising sign?
Because the zodiacs are about 24.2 degrees apart. A tropical Gemini ascendant in the first 24°14′ of the sign is a sidereal Taurus ascendant; both are the same horizon, measured from two starting points.
