Scorpio 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 Scorpio ascendant as a person who arrives holding back: the first impression is of intensity, stillness and eyes that give away less than they take in, and the body tends to be compact and controlled. Mars rules the chart in the classical tradition, Pluto in modern practice, so the whole life is framed as something with depths.
The honest shadow is the same reserve from the other side: a suspicion others feel before they feel the loyalty, a magnetism that can be used, and a first impression of threat the person did not intend. The tradition keeps the depth and the sting together.
What the Vedic tradition says of the lagna
Meets things by holding back. Little is given away early, a good deal is noticed, and trust is extended in stages rather than at once. That is the sidereal Scorpio, which is the rising sign of a different set of people from the tropical one; the section below says which.
The two-hour window
Scorpio takes about two and a half hours to rise in Britain, a long window, so an uncertain birth time is less likely to change it than it would an Aries or Pisces rising.
One sign, two ascendants
If Scorpio was rising in your Western chart, Libra 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 Scorpio, which is 81 per cent of the sign, is sidereal Libra; only a birth in the last 5°46′ of the sign, the last 19 per cent of the window, keeps Scorpio 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 Scorpio ascendant in the first 24°14′ of the sign is a sidereal Libra ascendant; both are the same horizon, measured from two starting points.
