Sagittarius 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 Sagittarius ascendant as a person who arrives open: the first impression is of friendliness, candour and a readiness to be interested, and the body tends to be long-limbed and restless, built for movement. Jupiter rules the chart, so the whole life is framed as a widening.
The honest shadow is the same openness from the other side: a tactlessness others meet before they meet the warmth, a restlessness that does not stay for the second conversation, and promises made on first meeting that the rest of the chart has to keep. The tradition does not pretend the archer always aims.
What the Vedic tradition says of the lagna
Meets things as a question of principle. The wider view arrives before the detail does, and the detail is often left for someone else. That is the sidereal Sagittarius, which is the rising sign of a different set of people from the tropical one; the section below says which.
The two-hour window
Sagittarius takes a little over two hours to rise in Britain, near the middle of the range; it is fully risen by mid-morning in early winter, which puts many Sagittarius risings in births around breakfast time at that season.
One sign, two ascendants
If Sagittarius was rising in your Western chart, Scorpio 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 Sagittarius, which is 81 per cent of the sign, is sidereal Scorpio; only a birth in the last 5°46′ of the sign, the last 19 per cent of the window, keeps Sagittarius 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 Sagittarius ascendant in the first 24°14′ of the sign is a sidereal Scorpio ascendant; both are the same horizon, measured from two starting points.
