About this tithi finder
This tool shows the panchang elements for any date in any of 11 supported Indian and Bangladeshi cities. The result is computed server-side so search engines and screen readers see the answer immediately — JavaScript is not required.
What you get
For the selected date and city, the tool reports:
- Tithi — the lunar day (e.g. Saptami, Shukla Paksha) and the time window it occupies.
- Nakshatra — the lunar mansion the Moon is in (one of 27).
- Yoga — the Sun–Moon longitude combination (one of 27).
- Karana — the half-tithi (one of 11), used for muhurat.
- Sun and Moon — local sunrise, sunset, moonrise, moonset.
How the tithi is calculated
A tithi is defined by the angular difference between the Moon\'s and Sun\'s ecliptic longitudes: each 12° of separation marks one tithi, so the lunar month contains 30 tithis. Because lunar speed varies, a tithi can last anywhere from about 19 hours to 26 hours — the tool shows both the active tithi at sunrise and its exact end time so you can see when it changes.
Paksha — why Shukla and Krishna matter
Each lunar month has two fortnights: Shukla Paksha (the waxing moon, from new moon to full moon) and Krishna Paksha (the waning moon, from full moon to next new moon). Festivals and vrats are usually fixed to a tithi within a specific paksha — for instance, Janmashtami is the 8th tithi of Krishna Paksha in the month of Bhadrapada.
Worked example
If you pick 23 May 2026 in Kolkata, the tool reports Saptami (Shukla Paksha) active from sunrise at 4:53 AM until 6:53 AM, when Ashtami takes over. The nakshatra for the day is Magha; the yoga rolls from Dhruva into Vyaghata mid-morning. This level of detail matches what a printed Drik Panchang would show.
