Panchang in Sevan, Gegharkunik, Armenia Wed 30 Oct 1974

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 05:17 on Wed 30 Oct to 05:18 on Thu 31 Oct, so only Wednesday night’s nishitha (00:17 Thu–01:10 Thu) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Sevan

Purnima follows the tithi at sunrise. Purnima runs from 05:17 on Wed 30 Oct to 05:18 on Thu 31 Oct, so it holds sunrise only on Wed 30 Oct, at 07:26. 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, 07:26 here. Chaturdashi ended at 05:17, before it. Purnima ends at 05:18 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 15 Oct, so the Moon is waxing: Shukla paksha.

The night of Tue 29 Oct ran from sunset 18:01 Tue to sunrise 07:26, 13 h 25 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:26 to 17:59, splits into 8 choghadiyas of 1 h 19 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:59 to 07:28 Thu, splits into 8 choghadiyas of 1 h 41 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 04:35 Thu, for Bharani.

Add the Sun's and the Moon's places among the stars: 192.8° + 1.9° = 194.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 16:34, then Siddhi.

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 17:22, when the lead reaches 174°; Bava until 05:18 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:26 to 07:28 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 14 Nov, finds it in Tula and begins Kartika.

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 15 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1974, 01:23 Sun. Since then the Sun has moved 213.4° round the stars. Vikram Samvat numbers that year 2031; Shaka Samvat numbers it 1896.
