Festival Rituals: The Living Ritual Calendar

Thirty-five festival observances across the year — the specific worship performed on each major festival day, spanning the pan-Indian calendar and the regional observances that sit alongside it.

Our Hindu Festivals Through the Year guide sets out the calendar. This one covers the worship performed on the day: thirty-five festival rituals recorded in Avyani's Master Puja & Ritual Catalogue.

Where this guide says tradition or regional practice, the custom is real and widely followed but has no single locator. Festival practice is where regional variation is widest, and dates differ between calendars even for the same festival.

How the Calendar Works

Almost every festival here follows the lunar calendar, which is why the Gregorian dates move each year. Two conventions matter, and they are the reason a festival can fall on different days in different states.

Tradition. The purnimanta reckoning ends the month at the full moon; the amanta ends it at the new moon. North India largely follows the first and the south and west the second, so the same festival can carry different month names. Only a few observances — Makar Sankranti among them, described in our Surya Rituals guide — are fixed to the solar calendar and fall on nearly the same date each year.

Spring

Holika Dahan is the bonfire on the night before Holi, commemorating Prahlad's deliverance; Holi Puja follows the next day. Basant Panchami honours Saraswati at the turn of the season, and Chaitra Navratri is the spring counterpart of the autumn nine nights, closing at Ram Navami.

Regional practice. The regional new years cluster here and are genuinely distinct festivals rather than local names for one: Gudi Padwa in Maharashtra, Ugadi in the Deccan, Vishu in Kerala with its kani arrangement viewed on waking, Poila Boishakh in Bengal with the opening of new account books, Baisakhi in Punjab and Bihu in Assam.

Monsoon and Early Autumn

Guru Purnima honours teachers, Nag Panchami the serpent deities, and Raksha Bandhan the sibling bond — the rakhi itself is covered in our Cloth and Sacred Threads guide. Onam and Thiruvonam mark Kerala's harvest and the homecoming of Mahabali.

Pitru Paksha, the sixteen-day ancestral fortnight, closes at Mahalaya Amavasya — which is also the day the Goddess is invoked in Bengal, so the ancestral fortnight ends exactly where Navratri begins. Our Shraddha and Pitru Karma guide covers the rites.

Navratri to Diwali

Sharadiya Navratri is the autumn nine nights, with Durga Puja Sandhi Puja at its heart — the forty-eight minutes spanning the junction of Ashtami and Navami, one of the most precisely timed observances in the tradition. Dussehra closes it.

Then the Diwali sequence: Naraka Chaturdashi, Deepavali Puja described in our Lakshmi Rituals guide, Govardhan Puja, and Bhai Dooj. Tulsi Vivah follows, marrying the tulsi plant to Vishnu and ending Chaturmas — after which weddings resume.

Kartik Purnima and Karthika Deepam close the season with lamps, the latter with the great fire lit on Arunachala at Tiruvannamalai.

Southern and Eastern Observances

Skanda Shashti is the six-day Murugan observance of Tamil Nadu, and Thaipusam its great vow-fulfilment festival, kept in Tamil Nadu and across the Tamil diaspora. Ayyappa Mandala Puja is the forty-one-day vrat preceding the Sabarimala pilgrimage, closing at Makara Vilakku — see our Temple Festivals and Special Sevas guide.

At Puri, Snana Yatra bathes the deities before the Rath Yatra and Bahuda Yatra brings them home. Ganga Dussehra honours the river's descent, and Rongker is a Karbi community observance of Assam.
