Times for this date are approximate. See calculation information below.
All times are local to your city. Tithi end is not the fast-breaking time.
Vrat day begins at sunrise: 05:04. Puja may be performed according to the interval or observance method below.
A day of Vishnu devotion, restraint and remembrance.
After bathing, make your sankalpa, worship Vishnu with flowers and Tulsi, offer naivedya, and spend time in prayer or Vishnu Sahasranama. Conclude the fast with an offering and Parana for your tradition.
The fasting date is not the Tithi start date. Smarta uses household sunrise rules; Gaudiya Vaishnava also considers Arunodaya and Mahadvadashi. Avoid grains and pulses according to your vow. Do not break during Hari Vasara; follow the applicable Parana entry.

Approximate/provisional timings use predicted Earth rotation or a Delta-T model outside measured coverage. Uncertainty grows for distant centuries and can affect observance dates. Historical timezone offsets are reconstructed; future timezone rules may change.
Yamaganda and daytime Gulika divide the existing sunrise-to-sunset interval into eight equal parts. Their weekday slots follow the usual Panchang convention. These are general daily windows, not a personal Muhurta recommendation.
Daily Moonrise/Moonset and relevant Vrat Moonrise reuse the existing ritual disc-centre convention without refraction. See Moon & Sun for the reference instant and horizon assumptions.
Brahma Muhurta uses the fourteenth of fifteen equal parts of the preceding sunset-to-sunrise night. Pradosh retains Avyani’s first fifth of the night; Nishita is its central fifteenth. These are declared conventions, not a claim that all traditions define them identically.
Durmuhurta uses weekday fifteenths of daylight; Tuesday also includes the seventh fifteenth of the night. Bhadra is the full Vishti Karana interval, without residence, face or tail subdivisions. Choghadiya divides day and night into eight parts each; Hora into twelve each. This daily Hora convention does not alter Kundali’s existing Hora calculation. Amrit in Choghadiya is a traditional slot name, not Nakshatra-based Amrit Kaal.
