Hindu calendar converter and festival dates

Why Hindu festivals move around — lunisolar + regional

Many Hindu festivals are tied to tithi, the lunar day, while the Gregorian calendar follows the solar year. That is why Holi, Diwali, Janmashtami, Raksha Bandhan, and Ganesh Chaturthi move each year. Panchang rules also depend on sunrise, moon phase, and location, so a festival can occasionally appear one day apart across cities or diaspora calendars.

Vikram Samvat vs Bengali vs Tamil — which year is “right”?

They are all right inside their own regional tradition. North Indian Vikram Samvat turns over around Chaitra in March or April. Gujarati Vikram Samvat turns over after Diwali, so it usually shows one lower year for much of the Gregorian year. Bengali, Tamil, Telugu, Malayalam, and Nanakshahi calendars use their own starts and names; this first release displays their year labels and marks full conversion as coming soon.

Diwali, Holi, and the festivals that anchor the calendar

Diwali lands on Kartika Amavasya, Holi follows Phalguna Purnima, and Navratri begins on Ashwin Shukla 1. These anchors make the calendar feel familiar even when the dates shift. The festival list here is table-backed for 2020-2030, which covers the common search window for upcoming Diwali, Holi, Navratri, Onam, and wedding-season planning dates.
