Panchang in Pāthardi, Maharashtra Fri 1 Nov 1963

Purnima follows the tithi at sunrise. Purnima runs from 23:14 on Thu 31 Oct to 19:25 on Fri 1 Nov, so it holds sunrise only on Fri 1 Nov, at 06:29. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Pāthardi

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, 06:29 here. Chaturdashi ended at 23:14 Thu, before it. Purnima ends at 19:25, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Oct, so the Moon is waxing: Shukla paksha.

The night of Thu 31 Oct ran from sunset 17:56 Thu to sunrise 06:29, 12 h 33 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 17:56, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:56 to 06:29 Sat, splits into 8 choghadiyas of 1 h 34 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 3 at 6°40′. It leaves at 16:41, for Bharani.

Add the Sun's and the Moon's places among the stars: 194.5° + 6.8° = 201.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 00:06 Sat, then Vyatipata.

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 09:20, when the lead reaches 174°; Bava until 19:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:29 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 17 Oct 18:12 Thu to 16 Nov 12:20 Sat the Sun stayed in Tula, entering Vrishchika at 16 Nov 16:09 Sat, after the new moon. A month with no sankranti is Adhika Kartika, before Kartika 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 17 Oct, with the Sun in Tula, began Kartika (Adhik). This Shukla paksha reads Kartika (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1963, 17:39 Mon. Since then the Sun has moved 213.7° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
