Panchang in Sevan, Gegharkunik, Armenia Wed 19 Jun 1940

Purnima follows the tithi at sunrise. Purnima runs from 03:25 on Wed 19 Jun to 02:01 on Thu 20 Jun, so it holds sunrise only on Wed 19 Jun, at 04:29. 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, 04:29 here. Chaturdashi ended at 03:25, before it. Purnima ends at 02:01 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 6 Jun, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:23, came before Chaturdashi ended at 05:55: this day reads Chaturdashi. Purnima ends at 04:31 Thu, before the next sunrise, so no day here reads Purnima: it is kshaya.

Sunrise here, 04:29, came after Chaturdashi ended at 03:25: this day reads Purnima.

The night of Tue 18 Jun ran from sunset 19:32 Tue to sunrise 04:29, 8 h 57 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:29 to 19:33, splits into 8 choghadiyas of 1 h 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:33 to 04:29 Thu, splits into 8 choghadiyas of 1 h 7 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 2 at 230°. It leaves at 16:26, for Mula.

Add the Sun's and the Moon's places among the stars: 64.6° + 233.2° = 297.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 19:05, then Shukla.

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 14:40, when the lead reaches 174°; Bava until 02:01 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:29 to 04:29 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 5 Jul, finds it in Mithuna and begins Ashadha.

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 6 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1940, 23:18 Sun. Since then the Sun has moved 69.8° round the stars. Vikram Samvat numbers that year 1997; Shaka Samvat numbers it 1862.
