Panchang in Pāthardi, Maharashtra Fri 30 Jul 1920

Purnima follows the tithi at sunrise. Purnima runs from 02:58 on Fri 30 Jul to 04:48 on Sat 31 Jul, so it holds sunrise only on Fri 30 Jul, at 06:04. 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, 06:04 here. Chaturdashi ended at 02:58, before it. Purnima ends at 04:48 Sat, when the lead reaches 180°. The lead passed 0° at the new moon of 16 Jul, so the Moon is waxing: Shukla paksha.

The night of Thu 29 Jul ran from sunset 19:06 Thu to sunrise 06:04, 10 h 58 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:04 to 19:05, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:05 to 06:05 Sat, splits into 8 choghadiyas of 1 h 22 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 2 at 270°. It leaves at 19:33, for Shravana.

Add the Sun's and the Moon's places among the stars: 103.8° + 273.2° = 377°, one full turn and 17°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 23:52, then Ayushmana.

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 15:56, when the lead reaches 174°; Bava until 04:48 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:04 to 06:05 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 16 Jul 01:54 Fri to 14 Aug 09:13 Sat the Sun stayed in Karka, entering Simha at 16 Aug 04:12 Mon, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 16 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1920, 16:25 Sat. Since then the Sun has moved 127° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
