Hindu festivals anchor to tithi (lunar day) and often to nakshatra or weekday rules. The civil calendar alone is insufficient for traditional timing.
Example: Ekadashi vrats
Ekadashi appears twice most months on the eleventh tithi of waxing and waning Moon. Families open the Vedic calendar, locate the marked tithi for their city, and confirm sunrise boundaries.
Example: Purnima and Amavasya
Full-moon and new-moon days drive Guru Purnima, many Devi observances, and pitru tarpana traditions. The calendar highlights these lunar phases per location.
Example: Multi-day festivals
Navaratri spans nine tithis; Diwali links to Amavasya in Kartika month. Scan the month view to see how Gregorian dates shift year to year.
Open the tool: Vedic calendar. Deep dive: Panchanga for muhurta on festival mornings.
