When is that tithi next?

Track a tithi

Three fields make a tithi: the lunar month, the fortnight — Shukla waxing, Krishna waning — and which of the fifteen days of that fortnight.

Month system. The two halves of India cut the lunar month at different points — amanta from new moon to new moon in the south, purnimanta from full moon to full moon in the north — so the same afternoon carries two month names for half of every month. Both are computed; pick the one your family uses and the page prints the other beside every date anyway. Why both →

Or start from a date you remember

For a tithi birthday, a shraddha or a vrat you keep on the anniversary of something — give the Gregorian date and this reads the tithi that was running at sunrise that morning, then fills the form above with it.

Read at the city in the bar at the top of this page. A tithi at sunrise in Chennai is occasionally not the tithi at sunrise in Delhi, so if the date belongs to somewhere else, set the city first.

Your list

A reminder that outlives this page

These dates can go straight into the calendar you already carry, with an alarm on each one. That is a deliberate choice over a notification from this site: a calendar entry survives this browser being cleared, works with no account and no permission prompt, and still fires next November if you never open Prahar again.

The file is written here and handed to your device; it never touches the network. On an iPhone it should open the Calendar import sheet — that is Apple’s behaviour rather than a web standard, and it has not been checked on a device by whoever built this page, so if nothing happens the dates above are still on screen to copy.

Why a tithi does not fall on the same date each year

A tithi is not a day. It is a 12° step of the Moon away from the Sun — thirty of them make a lunation, from one new moon to the next. Because the Moon closes that angle at a rate that changes through its orbit, a tithi runs anywhere from about 19 to about 26 hours, and a lunation is 29.53 days against a Gregorian year of 365.24. So the same tithi drifts about eleven days earlier each year and then jumps forward again when an extra month is inserted.

This is exactly why the dates below are solved one at a time rather than repeated by a calendar rule. A yearly repeat set on last year’s date would be wrong by up to three weeks, and would be wrong confidently.

Two mornings, and no mornings

A tithi belongs to the day at whose sunrise it is running. That convention is what makes “today’s tithi” a phrase at all, and it is the same one the daily panchang quotes the five limbs by. Two things follow that a table of dates usually hides:

A tithi can touch two sunrises. If it begins just before one morning and is still running at the next, there are two candidate days. Which one carries a vrat depends on the vrat and on the region — Ekadashi and Sankashti Chaturthi resolve it differently, and so do families. This page shows both days and does not choose, because choosing would be inventing a ruling.

And a tithi can touch none. A short tithi that begins after one sunrise and ends before the next is kshaya — skipped. There is no day it falls on that month. It is marked as skipped rather than rounded to the nearest morning, and nothing is written into your calendar for it.

Both are ordinary. Over a year at one city, roughly one tithi in thirty-five spans two sunrises and about one in twenty spans none.

The extra month

Roughly every third year a lunar month contains no solar ingress at all, and that month is adhika — intercalary. It carries the same name as the real month that follows it, so in such a year “Jyeshtha Shukla Ekadashi” happens twice, about thirty days apart. 2026 is one of those years. The Intercalary months field decides which of the two you are tracking; counting both is the default, because a reader asking when a name comes round usually wants to be told it comes round twice.
