Tithi calendar — the days families keep.

A tithi is a lunar day, and the observances that matter most in Hindu practice fall on particular ones. Ekadashi, Pradosham, Sankashti, Amavasya, Pournami and Ashtami all recur every lunar month, and the dates shift each time. Here they are for the months ahead, with what each is for.

✓ Always free✓ No birth details neededTwo months aheadRitual for each

A tithi is not a day, which is why dates move. It is the time the Moon takes to gain twelve degrees on the Sun — between about nineteen and twenty-six hours — so it rarely aligns with sunrise, and an observance is kept on the day the tithi is running at the relevant hour. How the dates are fixed →

The recurring observances

Which tithi, and what is kept on it

Each recurs every lunar month — most twice, since the waxing and waning halves both carry the same tithi numbers.

ObservanceTithiDeityHow oftenWhat is done
Ekadashi11thVishnuTwice a monthFasting from grains, kept from sunrise to the following morning. The most widely observed of all
Pradosham13thShivaTwice a monthEvening worship in the hour and a half before and after sunset. Abhishekam at Shiva temples
Sankashti Chaturthi4th — waningGanapathiMonthlyFast broken at moonrise, not sunset. For the removal of obstacles

Amavasya30th — new moonAncestorsMonthlyTarpanam and shraddha for the departed. Also the day for Pratyangira and Kali rites

Ashtami8thDurga, BhairavaTwice a monthKrishna Ashtami is the traditional day for Kala Bhairava rites
Shashti6thMuruganTwice a monthKept especially in Tamil Nadu. Skanda Shashti in Aippasi is the major observance

Sankashti is the one people most often get wrong. Unlike every other fast here, it is broken at moonrise rather than at sunset — and moonrise on a waning fourth is late, often after nine in the evening. It also varies by city more than any other timing on this page, so a date alone is not enough.

Skipped or repeated tithis in the two months shown

Krishna Dwitiya spans two local sunrises (vriddhi tithi).

Shashthi did not touch local sunrise before this date (kshaya tithi); sunset and moonrise observances were still tested at their own moments.

Pratipada did not touch local sunrise before this date (kshaya tithi); sunset and moonrise observances were still tested at their own moments.

Shukla Ashtami spans two local sunrises (vriddhi tithi).

Dashami did not touch local sunrise before this date (kshaya tithi); sunset and moonrise observances were still tested at their own moments.

Which day gets the tithi

The general rule is the tithi running at sunrise names the day. But observances have their own rules: Ekadashi is kept on the day the tithi covers sunrise, while Pradosham depends on the tithi running at sunset, and Sankashti on the tithi at moonrise.

This is why two observances can appear to fall on different days in different calendars — they are following different rules correctly.

Shukla and Krishna paksha

The lunar month divides into the waxing fortnight, shukla paksha, ending at the full moon, and the waning fortnight, krishna paksha, ending at the new moon. Tithis one to fifteen run in each.

So most tithis occur twice a month, and the two are read differently — Krishna Ashtami is the Bhairava day, while Shukla Ashtami is not.

Timezone changes the date

A tithi begins and ends at a precise moment worldwide, but which calendar date that falls on depends on where you are. An Ekadashi beginning at 2 AM in India may begin the previous afternoon in North America.

Families abroad usually keep the local date rather than the Indian one. Set your city above and the dates adjust.

The thirty tithis

Fifteen in each paksha. Several carry names and observances of their own; the rest are used mainly in muhurta.

13TrayodashiJayaShiva. Pradosham, twice each month
14ChaturdashiRiktaShiva. Masik Shivaratri in the waning half
15Pournami / AmavasyaPurnaFull moon in shukla, new moon in krishna

The Rikta tithis — 4th, 9th and 14th — are avoided for beginnings. The name means empty, and classical practice does not start journeys, businesses or auspicious undertakings on them. That they are also the days of Ganapathi, Durga and Shiva observances is not a contradiction: worship is not a beginning, and none of these restrictions apply to ritual.

When calendars disagree

Two panchangs can give different dates for the same observance, and both be right. Ekadashi is fixed by the tithi at sunrise, Pradosham by the tithi at sunset, Sankashti by the tithi at moonrise. Where a tithi begins or ends near one of those moments, the rule decides the day — and traditions weight the rules slightly differently.

Smarta and Vaishnava Ekadashi dates differ deliberately. Where the eleventh tithi is touched by the tenth at sunrise, Vaishnava practice defers the fast to the following day while Smarta practice does not. This is a settled difference of observance, not an error in either calendar.

Follow your family’s practice rather than a website. Where a date here differs from what your family or temple keeps, theirs is the one to follow — a calendar cannot know which tradition you belong to. If something matters and you are unsure, ask the priest who will perform it.

Two calendars, running at once

Indian timekeeping runs on the Moon and the Sun together. The solar month begins when the Sun enters a new rashi, at Sankranti, and governs the Tamil and Malayalam calendars and the agricultural year. The lunar month is measured in tithis and governs almost every observance — Ekadashi, Pradosham, Amavasya, and the great festivals.

Because a lunar month is about twenty-nine and a half days and a solar year is not divisible by it, the two drift apart and are periodically reconciled by an intercalary month, adhika masa. This is why Diwali and Navratri move by a fortnight or more between years while Pongal barely moves at all: one is lunar, the other solar.

What follows from this practically is that observance dates cannot be memorised. They must be calculated each year, for each location — which is what a panchang has always been for, and what this page does.

Questions

About tithis

Most often the Smarta and Vaishnava difference. Where the eleventh tithi is touched by the tenth at sunrise, Vaishnava practice defers the fast by a day while Smarta practice does not — so the two traditions keep different dates deliberately. Follow your family’s or your temple’s practice; a calendar cannot know which tradition you belong to.

At moonrise, not at sunset — and this is the detail most often missed. Moonrise on a waning fourth is late, commonly after nine in the evening, and it varies by city more than any other timing here. Set your location above so the moonrise time is right for where you are.

Because most follow the lunar calendar. A lunar month is about twenty-nine and a half days, so twelve of them fall short of a solar year by roughly eleven days — which is why Diwali and Navratri shift each year, and why an extra month is inserted periodically to reconcile them. Solar observances such as Pongal barely move at all.

Yes, and both are normal. A tithi that begins and ends between two sunrises is skipped — kshaya tithi — and one that covers two sunrises is repeated, vriddhi tithi. Neither is inauspicious in itself; they are consequences of the tithi being between nineteen and twenty-six hours long while a day is twenty-four.

Most families keep the local date, since the observance rules depend on local sunrise, sunset and moonrise. A tithi begins at one moment worldwide but falls on different calendar dates by timezone. Set your city above and the dates adjust. Where a family keeps the Indian date by preference, that is also a settled practice and not wrong.

The 4th, 9th and 14th. Rikta means empty, and classical practice avoids them for beginnings — starting a journey, a business, or anything auspicious. They are not avoided for worship, which is why Sankashti, Navami and Shivaratri all fall on them. Worship is not a beginning, and none of these restrictions apply to ritual.

Depends what for. Pournami is the most generally auspicious for worship; Dashami and Tritiya are favoured for beginnings; Ekadashi is the most widely kept as a fast. For choosing a date for something specific, the tithi is one factor among several — the Muhurat Finder weighs them together.

Observing a tithi is one thing. Performing the rite is another.

Several of these tithis carry rituals traditionally performed at a temple rather than at home — Pradosham abhishekam, Amavasya tarpanam, Krishna Ashtami Bhairava rites. Our priests perform them at our own Yagna Ashram, individually and in your name, on the correct tithi.
