What is Lagna?
Lagna is the Ascendant: the zodiac sign rising on the eastern horizon at birth, and the starting point of the twelve houses in a Vedic chart.
The sign on the eastern horizon
Lagna is the Ascendant. At the recorded birth time, one zodiac sign is rising in the east. That sign becomes the first house, and the remaining houses follow in order around the chart.
Because the Earth turns, Lagna changes about every two hours. Two people born on the same day in the same city can have different rising signs if they were born a few hours apart. That is why birth time matters more for Lagna than for the Sun sign.
How astrologers use it
In Vedic astrology the Lagna is one of the three anchors of the chart, alongside the Moon and the Sun. It describes the bodily presence and the lens through which the rest of the chart is counted. House meanings — career in the tenth, partnership in the seventh — are measured from this point.
A short note about the rising sign is useful context. It is not a complete reading. The planets that occupy or aspect the Lagna, and the lord of that sign, are part of the same picture.
Common questions
- Why does Lagna need a birth time?
- The eastern horizon moves through a sign in roughly two hours. Without a clock time, the rising sign cannot be placed, and the houses that begin from it cannot be drawn.
