How the date is set
Date: Thiruvonam (Shravana) nakshatra at sunrise while the Sun is in Simha (Chingam).
Lunar months here are amanta (new moon to new moon); in the purnimanta reckoning used in much of North India, the Krishna paksha belongs to the next month. Communities follow their own rules for some festivals, so a local almanac may keep a few on a neighbouring day.
Dates are computed with this site's panchang (Lahiri ayanamsa) for New Delhi. Times of sunrise and the tithi differ by place, so a date can shift by a day for cities far from Delhi; the calendar pages recalculate for your city. All festivals →
