Panchang in Pāthardi, Maharashtra Thu 1 Oct 2020

Purnima follows the tithi at sunrise. Purnima runs from 00:26 on Thu 1 Oct to 02:35 on Fri 2 Oct, so it holds sunrise only on Thu 1 Oct, at 06:19. 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, 06:19 here. Chaturdashi ended at 00:26, before it. Purnima ends at 02:35 Fri, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Sep, so the Moon is waxing: Shukla paksha.

The night of Wed 30 Sep ran from sunset 18:18 Wed to sunrise 06:19, 12 h 1 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 18:17, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 06:20 Fri, splits into 8 choghadiyas of 1 h 30 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 05:56 Fri, for Revati.

Add the Sun's and the Moon's places among the stars: 164.2° + 334.9° = 499.1°, one full turn and 139.1°. 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 20:25, 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 13:29, when the lead reaches 174°; Bava until 02:35 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:20 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 16:30 Thu to 17 Oct 01:01 Sat the Sun stayed in Kanya, entering Tula at 17 Oct 07:05 Sat, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina 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 Sep, with the Sun in Kanya, began Ashwina (Adhik). This Shukla paksha reads Ashwina (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2020, 14:58 Tue. Since then the Sun has moved 184.1° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
