Panchang in Sevan, Gegharkunik, Armenia Fri 1 Aug 1947

Purnima follows the tithi at sunrise. Purnima runs from 02:32 on Fri 1 Aug to 04:49 on Sat 2 Aug, so it holds sunrise only on Fri 1 Aug, at 04:55. 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, 04:55 here. Chaturdashi ended at 02:32, before it. Purnima ends at 04:49 Sat, when the lead reaches 180°. The lead passed 0° at the new moon of 18 Jul, so the Moon is waxing: Shukla paksha.

The night of Thu 31 Jul ran from sunset 19:17 Thu to sunrise 04:55, 9 h 38 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:55 to 19:16, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:16 to 04:56 Sat, splits into 8 choghadiyas of 1 h 12 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 17:07, for Shravana.

Add the Sun's and the Moon's places among the stars: 104.9° + 274° = 378.9°, one full turn and 18.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 19:34, then Ayushmana.

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 15:42, when the lead reaches 174°; Bava until 04:49 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:55 to 04:56 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 07:15 Fri to 16 Aug 14:12 Sat the Sun stayed in Karka, entering Simha at 16 Aug 23:42 Sat, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 18 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 1947, 19:34 Sat. Since then the Sun has moved 126.8° round the stars. Vikram Samvat numbers that year 2004; Shaka Samvat numbers it 1869.
