Panchang in Sevan, Gegharkunik, Armenia Wed 16 Sep 1959

Purnima follows the tithi at sunrise. Purnima runs from 04:51 on Wed 16 Sep to 04:51 on Thu 17 Sep, so it holds sunrise only on Wed 16 Sep, at 06:40. 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, 06:40 here. Chaturdashi ended at 04:51, before it. Purnima ends at 04:51 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 3 Sep, so the Moon is waxing: Shukla paksha.

The night of Tue 15 Sep ran from sunset 19:10 Tue to sunrise 06:40, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 19:08, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:08 to 06:41 Thu, splits into 8 choghadiyas of 1 h 26 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 4 at 316°40′. It leaves at 10:07, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 149.2° + 318.1° = 467.3°, one full turn and 107.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 04:30 Thu, then Ganda.

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 runs until 16:47, when the lead reaches 174°; Bava until 04:51 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:41 Thu, so the hours after midnight still belong to Budhawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 2 Oct, finds it in Kanya and begins Ashwina.

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 3 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 1959, 07:29 Wed. Since then the Sun has moved 154.9° round the stars. Vikram Samvat numbers that year 2016; Shaka Samvat numbers it 1881.
