Free Lagna Calculator: your Vedic Ascendant
The Lagna anchors your entire birth chart. Vidhata computes the sidereal Lagna with Lahiri ayanamsa from your exact birth time and place, to the arc-minute, with nakshatra and pada.
Lagna (also called Ascendant or rising sign) is the rashi rising on the eastern horizon at the moment of your birth. It defines the 1st house, sets the count for every other house, and shapes the visible self: physical body, temperament, the way you meet the world. Two charts with identical planet positions but different Lagnas read very differently. The Lagna lord (the planet ruling your Lagna rashi) is one of the most important planets in your chart.
Lagna shifts roughly one degree every four minutes. A 10-minute drift in birth time can change the Lagna degree, sometimes the rashi entirely. House cusps move with it. Navamsa Lagna shifts even faster. Accurate birth time is therefore non-negotiable for a useful chart. If your birth time is uncertain, Vidhata supports rectification through major life events.
What you get
Lagna nakshatra and pada
The lunar mansion the Lagna degree falls in, and which of the four padas.
Lagna lord placement
Where the ruling planet of your Lagna sits: house, sign, dignity. A primary diagnostic for life direction.
Vargottama check
Whether your Lagna stays in the same sign in D9 (Navamsa). A marker of personal strength.
Special lagnas
Bhava Lagna, Hora Lagna, Ghati Lagna and Sree Lagna for advanced chart reading.
Sun sign and Moon sign
Computed alongside Lagna so you have all three "signs" Indian astrology actually cares about.
How it works
- 1
Enter birth time precisely
Lagna shifts one degree per four minutes. Provide birth time as exactly as you can.
- 2
Geocode birth place
Vidhata converts city to latitude/longitude and applies the historical timezone.
- 3
Read your Lagna and lord
The Lagna rashi names the visible self. The Lagna lord's placement names the life direction.
- 4
Cross-check with Navamsa Lagna
A vargottama Lagna (same rashi in D1 and D9) is a strong indicator. Vidhata flags it.
Frequently asked questions
What is Lagna?+
Lagna (Ascendant) is the rashi rising on the eastern horizon at the moment of your birth. It defines the 1st house in your chart and anchors every other house. In Vedic reading, Lagna often matters more than the Sun sign.
How is Lagna different from Sun sign?+
Sun sign is the rashi the Sun was in at birth and changes once a month. Lagna changes every two hours. Two people born the same day in the same city have the same Sun sign but usually different Lagnas. Vedic astrology reads charts primarily from the Lagna, secondarily from the Moon.
What does the Lagna lord mean?+
The Lagna lord is the planet ruling your Lagna rashi. Its house position, sign placement, dignity and aspects describe the trajectory of your life. A strong, well-placed Lagna lord is one of the most reliable yogas in classical Vedic astrology.
Why does birth time matter so much for Lagna?+
Lagna shifts one degree every four minutes. Across two hours it crosses an entire rashi. A 30-minute drift in recorded birth time can put you in the wrong Lagna rashi entirely, and every house lord changes with it. If your birth time is uncertain, life-event rectification is essential.
What is vargottama Lagna?+
A Lagna that occupies the same rashi in both D1 and D9 (Navamsa) is called vargottama. Tradition treats this as a strong marker of personal stability and dharmic alignment.
