Find your lagna (ascendant) — the sign rising on the eastern horizon at your birth, with its exact degree, element and ruling planet, plus your birth chart. An accurate birth time and place are essential. Computed in the sidereal (Lahiri) system.
How your lagna is calculated
The lagna is the zodiac sign rising on the eastern horizon at the exact moment and place of your birth. Because the Earth turns about 1 degree every 4 minutes, the rising sign changes roughly every 2 hours — so a precise birth time and geographic coordinates are essential. This tool computes the ascending sidereal (Lahiri) degree for your birth data, identifies the lagna sign, its element and ruling planet (the lagna lord), and draws your birth chart with all 12 houses.
Frequently asked questions
What is the lagna (ascendant)?
The lagna is the zodiac sign rising on the eastern horizon at your birth. It defines the first house of your chart and anchors the other eleven, shaping how each planet's influence is expressed.
Why do I need an exact birth time for the lagna?
The ascendant changes about every two hours, so even a small error in birth time can shift your lagna to a neighbouring sign. An accurate time and birthplace are essential for a reliable ascendant.
What if I don't know my birth time?
Without a birth time the lagna cannot be determined reliably. Your moon sign and sun sign, shown alongside, do not depend on the exact time and can still be read.
What is the lagna lord?
The lagna lord is the planet that rules your ascendant sign. It acts as the ruler of the whole chart and is considered to colour your overall life direction.
Is this a prediction?
No. It is an astronomical calculation of your ascendant and its attributes, shown for reflection rather than as a prediction.
