In short
On October 17, 2026 (India, IST), tithi is Shukla Paksha Saptami (until 8:28 AM, Oct 18).
What is Tithi?
The tithi is the Hindu lunar day — most vratas, fasts and festivals are fixed by it.
The tithi is the lunar day — the time it takes the Moon to gain 12° on the Sun. There are 30 tithis in a lunar month, 15 in the waxing fortnight (Shukla Paksha) and 15 in the waning fortnight (Krishna Paksha), running Pratipada, Dwitiya, Tritiya … up to Purnima (full moon) or Amavasya (new moon).
Most Hindu observances follow the tithi rather than the weekday: Ekadashi fasts, Sankashti and Vinayaka Chaturthi, Pradosham (Trayodashi), Purnima and Amavasya vratas are all tithi-based. The tithi prevailing at sunrise usually governs the day's observance, though some vratas use the tithi at a specific time (such as moonrise or midday).
A tithi does not align neatly with the 24-hour civil day — it can start and end at any clock time, so the tithi may change partway through the day. This page shows the tithi at today's sunrise and the time it ends.

FAQ
What is the tithi today (October 17, 2026)?
Tithi on October 17, 2026 is Shukla Paksha Saptami (until 8:28 AM, Oct 18) (India, IST).
What is a tithi?
A tithi is a lunar day — the period during which the Moon gains 12° of longitude on the Sun. There are 30 in a lunar month, across the Shukla (waxing) and Krishna (waning) pakshas.
How many tithis are there?
There are 30 tithis in a lunar month — Pratipada, Dwitiya, Tritiya, Chaturthi, Panchami, Shashthi, Saptami, Ashtami, Navami, Dashami, Ekadashi, Dwadashi, Trayodashi, Chaturdashi and Purnima/Amavasya — repeating once in each paksha.
Which tithi governs a fast or festival?
Usually the tithi prevailing at sunrise governs the day's observance, though some vratas follow the tithi at moonrise, midday or another fixed time.
Why does the tithi change during the day?
A tithi is astronomical and does not match the 24-hour clock, so it can begin or end at any time — the tithi may change partway through a civil day.
What is a Kshaya or Vriddhi tithi?
A Kshaya (lost) tithi is one that starts and ends without ever touching a sunrise, so it is skipped; a Vriddhi (extended) tithi spans two sunrises and so appears on two days. This is why a festival date can shift by a day.
What are Rikta tithis?
Rikta ("empty") tithis are the Chaturthi (4th), Navami (9th) and Chaturdashi (14th). They are considered inauspicious for beginning new, auspicious work, though they suit bold or destructive tasks.
How this is calculated
Timings are computed with the Drik (observational) method using the Lahiri (Chitra-paksha) ayanamsha, for India (IST) with Hyderabad as the reference location. Sunrise- and sunset-based windows — Rahu Kalam, Choghadiya and the muhurtas — are derived from the day's actual sunrise and sunset, so they shift a few minutes by city.
