India Calendar

India runs on a single time zone nationwide — Indian Standard Time (UTC+5:30) — despite spanning nearly 3,000 km east to west. The Gregorian calendar governs official and business life, while the lunisolar Hindu calendar (Panchang) and the Islamic Hijri calendar set the dates for most religious festivals, which is why holidays like Diwali, Holi and Eid shift each year.

India observes three fixed national holidays — Republic Day, Independence Day and Gandhi Jayanti — plus a long list of gazetted holidays that vary by state. Most festival dates follow lunar or lunisolar calendars, so they move from year to year.
