Rising Sign (Lagna) Calculator
Instant and free — no signup, nothing stored. The lagna is computed in your browser on the same sidereal (Lahiri) engine as this site's full kundli tool — which is also completely free, PDF included.
Why the lagna is the chart's frame
The lagna (ascendant) is the sign rising on the eastern horizon at your birth — the first house, from which every other house is counted. It shapes constitution, temperament and the chart's whole orientation: two people with identical planets but different lagnas live different charts. It moves through all twelve signs every day, changing roughly every two hours — which is why the exact birth time matters here more than anywhere else in Jyotish.
Vedic vs Western ascendant
Western calculators return a tropical ascendant; this tool returns the sidereal lagna used in Vedic astrology, about 24° earlier — so a Western "Leo rising" is often a Vedic Karka (Cancer) lagna. Both are computed correctly; they measure against different zodiacs.
Uncertain birth time?
If your recorded time might be off by more than a few minutes, treat the result as provisional — and know that a lost or doubtful birth time can be reconstructed: birth-time rectification works backward from major life events to fix the lagna. This is done in consultation. Meanwhile, your moon sign and nakshatra are far less time-sensitive.
Frequently asked questions
What is my rising sign in Vedic astrology?
Your rising sign (lagna) is the zodiac sign that was climbing the eastern horizon at your exact birth moment, measured in the sidereal zodiac. It is the first house of your kundli — enter your birth details above for the instant answer.
Why does the lagna need my exact birth time?
The ascendant changes sign roughly every two hours, so even a 15-minute error can move it. If your time is approximate, treat the result as provisional; a birth-time rectification consultation can settle it.
Why is my Vedic rising sign different from Western sites?
Vedic astrology uses the sidereal zodiac (Lahiri ayanamsha), about 24 degrees behind the tropical zodiac Western calculators use — so your Vedic lagna is often one sign earlier than a Western 'ascendant' result.
Lagna, moon sign, sun sign — which matters most?
In Vedic practice the lagna frames the whole chart (health, self, direction), the moon sign carries mind and dashas, and the sun sign is one planet among nine. A full reading weighs all three — the free kundli gives you the complete picture.
From the lagna to the chart
The lagna opens the chart; the reading is the chart. Get the full kundli — free, with PDF download, or consult Dr. R.P. Sharma (practising since 1979) online anywhere at a flat fee of ₹5,100.
