Panchang in Sevan, Gegharkunik, Armenia Thu 1 Sep 2050

Purnima follows the tithi at sunrise. Purnima runs from 17:25 on Wed 31 Aug to 13:30 on Thu 1 Sep, so it holds sunrise only on Thu 1 Sep, at 06:27. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:27 here. Chaturdashi ended at 17:25 Wed, before it. Purnima ends at 13:30, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Aug, so the Moon is waxing: Shukla paksha.

The night of Wed 31 Aug ran from sunset 19:33 Wed to sunrise 06:27, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:27 to 19:32, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:32 to 06:28 Fri, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 2 at 310°. It leaves at 21:58, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 134.3° + 310.1° = 444.4°, one full turn and 84.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 19:36, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 03:29, when the lead reached 174°; Bava runs until 13:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:27 to 06:28 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 15:47 Wed to 16 Sep 07:49 Fri the Sun stayed in Simha, entering Kanya at 17 Sep 10:03 Sat, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada itself.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 17 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2050, 04:41 Wed. Since then the Sun has moved 156.3° round the stars. Vikram Samvat numbers that year 2107; Shaka Samvat numbers it 1972.
