Eclipses (Grahan) and Sutak: Meaning, Timing and Customs

What solar and lunar eclipses mean in Vedic tradition, why visibility decides whether Sutak applies, and the customs observed around a grahan.

An eclipse (grahan) is one of the most significant astronomical events in the Vedic calendar. A solar eclipse (Surya Grahan) occurs at Amavasya when the Moon passes between Earth and Sun; a lunar eclipse (Chandra Grahan) occurs at Purnima when Earth's shadow falls on the Moon.

Visibility decides everything

In Vedic practice, an eclipse "counts" only where it is visible. If a grahan is not visible from your location, its Sutak and observances do not apply there. This is why our eclipse pages show visibility for India specifically.

Sutak — the inauspicious period before

Sutak is the cautionary window before (and during) a visible eclipse:

• •Solar eclipse: Sutak begins about 12 hours before.
• •Lunar eclipse: Sutak begins about 9 hours before.

During Sutak, temples close, new and auspicious activities pause, and many avoid cooking and eating.

Customs observed

Traditionally people bathe before and after, chant or meditate during the eclipse, avoid sleeping and eating, and donate (daan) afterwards. Pregnant women are advised extra rest. After the eclipse ends, homes and idols are cleansed and fresh food is prepared.

The science alongside the tradition

Eclipses are entirely predictable astronomically. Our eclipse tool lists every solar and lunar eclipse for a year with its type (total, partial, annular, penumbral), precise timings and whether it is visible from India — so you can observe the tradition with accurate timing.
