Panchang in Pāthardi, Maharashtra Sun 1 Aug 1909

Purnima follows the tithi at sunrise. Purnima runs from 05:15 on Sun 1 Aug to 02:43 on Mon 2 Aug, so it holds sunrise only on Sun 1 Aug, at 06:05. 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, 06:05 here. Chaturdashi ended at 05:15, before it. Purnima ends at 02:43 Mon, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

The night of Sat 31 Jul ran from sunset 19:05 Sat to sunrise 06:05, 11 h 0 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 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 Mon, 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 3 at 273°20′. It leaves at 16:11, for Shravana.

Add the Sun's and the Moon's places among the stars: 105.5° + 274° = 379.5°, one full turn and 19.5°. 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 17:21, 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 16:02, when the lead reaches 174°; Bava until 02:43 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:05 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 16:14 Sat to 16 Aug 05:24 Mon the Sun stayed in Karka, entering Simha at 16 Aug 08:35 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 17 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: 22 Mar 1909, 01:41 Mon. Since then the Sun has moved 127.5° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
