Major Hindu Vrat Festivals: A Complete Fasting Guide

India observes more vrats than any other living tradition keeps active calendars for. Some are daily, some monthly, some annual; some last a few hours, others nine nights. For anyone trying to make sense of the calendar — or pick which fasts to actually observe — this guide is a working reference to the major Hindu vrat festivals, what each commemorates, and how the fasting rules differ between them.

The dates of all of these vrats are determined by the lunar Panchang dates rather than the Gregorian calendar. They shift year to year, which is why a single static guide can name the festivals but never the dates — those need to be checked against the Panchang for the year you’re observing.

Ekadashi Vrat: The 11th Lunar Day Fast

Ekadashi is the most commonly observed of all Hindu vrats. It falls twice a month — once in Shukla Paksha and once in Krishna Paksha — for a total of 24 Ekadashis a year. Each has a name (Putrada Ekadashi, Mokshada Ekadashi, Devshayani Ekadashi, and so on) and a specific spiritual significance, but the underlying observance is the same: a fast dedicated to Lord Vishnu, broken the following morning during a window called parana.

Standard Ekadashi rules: no grains (chawal, gehun), no lentils, no onion or garlic. Phalahar (fruit, milk, sabudana, kuttu, singhara) is permitted. Many devotees observe a stricter variant — no salt, or full nirjala (no water).

The most demanding Ekadashi of the year is Nirjala Ekadashi in Jyeshtha (typically June). Observed without food or water for a full 24 hours, it is said in the Padma Purana to carry the merit of all 24 Ekadashis combined — which is why it remains the one most non-regular fasters attempt at least once a year.

Navratri Fasting: Nine Nights, Nine Forms of Devi

Navratri runs for nine nights twice a year — Sharad Navratri in autumn (the more widely observed) and Chaitra Navratri in spring. Each of the nine days is dedicated to one of the nine forms of Durga: Shailaputri, Brahmacharini, Chandraghanta, and so on, culminating in Siddhidatri.

The Navratri fast is gentler than Ekadashi but longer. Devotees eat once a day, restrict food to vrat-permitted ingredients (no regular salt — only sendha namak; no grains except buckwheat, water chestnut flour, and sabudana), and avoid non-vegetarian food and alcohol for all nine days. The full list of allowed and prohibited ingredients can get confusing — our guide to vrat-friendly recipes covers what works.

Mahashivratri: The Great Night of Shiva

Mahashivratri falls on the Chaturdashi (14th tithi) of Krishna Paksha in Phalguna, usually in February or March. It marks the night Shiva is said to have performed the Tandava and, in another tradition, the night Shiva and Parvati were wed.

The fast is full-day, broken only the following morning. Many devotees observe a night vigil — staying awake through the four three-hour prahar of the night and offering bilva leaves, milk, and water to a Shivalinga at each prahar transition. Of all the vrats listed here, Mahashivratri is the one most actively kept by men and women in equal measure.

Pradosh Vrat: The Twilight Fast

Pradosh falls twice a month, on the Trayodashi (13th tithi) of both pakshas. The fast is observed through the day but the puja itself is performed during pradosh kaal — roughly 1.5 hours straddling sunset. The fast is broken at the end of pradosh kaal, not the next morning.

Pradosh is dedicated to Lord Shiva. When the trayodashi falls on a Monday it is called Som Pradosh; on a Tuesday, Bhaum Pradosh; on a Saturday, Shani Pradosh — and each variant carries its own benefits in the traditional literature.

Purnima and Amavasya Observances

Purnima (full moon) and amavasya (new moon) are not fasts in the strict Ekadashi sense, but they are days when many devotees keep light vrats, perform shradh (rituals for ancestors), and avoid certain foods. Specific purnimas — Guru Purnima in Ashadha, Kartik Purnima in Kartika, Buddha Purnima in Vaishakha — are major observances in their own right.

Amavasya, the dark moon, is traditionally associated with ancestor rituals. Mauni Amavasya in Magha and Mahalaya Amavasya at the start of Pitru Paksha are the most widely observed.

Sankashti Chaturthi: The Monthly Fast for Ganesha

Sankashti Chaturthi falls on the Chaturthi (4th tithi) of Krishna Paksha each month — twelve fasts a year, each dedicated to Lord Ganesha and intended to remove obstacles (sankashti literally means “deliverance from difficulty”). The fast is broken in the evening after moonrise, following a puja to Ganesha and the recital of the Sankashti vrat katha. When Sankashti falls on a Tuesday, it becomes Angarki Chaturthi — considered the most powerful Sankashti of the year.

How to Prepare for Each Vrat: A Practical Checklist

Regardless of which of the major Hindu vrat festivals you’re observing, four preparations make every one of them easier:

The night before: eat a light dinner, no heavy grains or fried food, and decide what your phalahar will be the next day.

The morning of: bathe before the puja, set a clear sankalpa (intention), and have the puja items ready so you aren’t scrambling later.

Through the day: drink water at intervals (unless observing nirjala), avoid argument and gossip — vrats are mental as much as physical — and rest more than you think you need.

Parana: break the fast at the time the tradition specifies, not when you feel hungry. Start small — fruit, milk, or one bowl of khichdi.

One thing worth noting across all of these vrats: the rules around food are less important than the rules around intention. A vrat observed mechanically — phalahar consumed without sankalpa, puja skipped for a Netflix episode — produces little of the inner shift the tradition is pointing at. Conversely, even a partial fast held with full attention will leave you noticeably calmer at the end of the day.

The hardest part of observing these vrats consistently is remembering when they fall. The Panchang shifts every year, dates change by region, and tithi boundaries don’t respect the Gregorian week. Get reminders for all these vrats in one place — the calendar work is done for you, so the only thing left is the observance.
