Leo 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 Leo ascendant as a person who arrives visibly: the first impression is of warmth, confidence and a certain theatre, and the body tends to carry itself well, with a notable head of hair or way of holding the head. The Sun rules the chart, so the whole life is framed as something to be seen doing.
The honest shadow is the same visibility from the other side: a pride others meet before they meet the generosity, a need for the room's attention on first contact, and a coolness when it is not given. The tradition does not pretend the lion is only warm.
What the Vedic tradition says of the lagna
Meets things visibly. There is little talent for being in a room without being noticed in it, and the discomfort comes from being overlooked rather than from being seen. That is the sidereal Leo, which is the rising sign of a different set of people from the tropical one; the section below says which.
The two-hour window
Leo takes about two and a half hours to rise in Britain, one of the longest windows, so it is among the commonest rising signs at British latitudes and a birth time known roughly is usually enough to be sure of it.
One sign, two ascendants
If Leo was rising in your Western chart, Cancer 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 Leo, which is 81 per cent of the sign, is sidereal Cancer; only a birth in the last 5°46′ of the sign, the last 19 per cent of the window, keeps Leo 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 Leo ascendant in the first 24°14′ of the sign is a sidereal Cancer ascendant; both are the same horizon, measured from two starting points.
