Panchang in Sevan, Gegharkunik, Armenia Wed 28 Mar 1945

Purnima follows the tithi at sunrise. Purnima runs from 18:22 on Tue 27 Mar to 20:44 on Wed 28 Mar, so it holds sunrise only on Wed 28 Mar, at 05:51. 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, 05:51 here. Chaturdashi ended at 18:22 Tue, before it. Purnima ends at 20:44, when the lead reaches 180°. The lead passed 0° at the new moon of 14 Mar, so the Moon is waxing: Shukla paksha.

The night of Tue 27 Mar ran from sunset 18:18 Tue to sunrise 05:51, 11 h 33 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:51 to 18:19, 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, 18:19 to 05:49 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 11:28, for Hasta.

Add the Sun's and the Moon's places among the stars: 344° + 157.2° = 501.2°, one full turn and 141.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 16:02, then Dhruva.

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 07:32, when the lead reaches 174°; Bava until 20:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:51 to 05:49 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 06:50 Wed to 12 Apr 15:29 Thu the Sun stayed in Meena, entering Mesha at 13 Apr 12:29 Fri, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 14 Mar, with the Sun in Meena, began Chaitra (Adhik). This Shukla paksha reads Chaitra (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 1945, 06:50 Wed. Since then the Sun has moved 13.9° round the stars. Vikram Samvat numbers that year 2002; Shaka Samvat numbers it 1867.
