Why do festival dates change every year?

They follow the lunar calendar, so they fall on different Gregorian dates each year — but always on the same Tithi and Nakshatra.

What is the difference between an Ekadashi and a Pradosh fast?

Ekadashi falls on the 11th lunar day of each fortnight and is dedicated to Vishnu. Pradosh is the 13th Tithi evening, dedicated to Shiva. Both are partial fasts.

About festivals

Hindu festivals, vrats and observances

Hindu festivals follow the lunar calendar and mark astronomical events, deity birthdays, mythological turning points or seasonal transitions. Most are tied to a specific Tithi and Nakshatra, which is why their Gregorian date shifts each year. This page lists the upcoming major festivals — when they begin, what they commemorate and how they are traditionally observed.

Categories of observance

Vrats are vow-fasts taken on specific Tithis (e.g. Ekadashi, Pradosh, Chaturthi). They combine dietary discipline with mantra japa and worship.

Major festivals like Diwali, Holi, Navaratri and Janmashtami are multi-day celebrations with regional variations.

Sankranti festivals mark the Sun's entry into a new sidereal sign — Makar Sankranti (Capricorn) is the most widely observed.

Regional variations

Festival names, foods and rituals differ across regions: Pongal in Tamil Nadu corresponds to Makar Sankranti elsewhere; Onam is specific to Kerala; Bihu to Assam; Durga Puja is celebrated most elaborately in Bengal. We list the pan-Indian astronomical date and note major regional names.
