Panchang in Mapleton, Utah, United States Tue 1 Aug 2023

Purnima follows the tithi at sunrise. Purnima runs from 16:22 on Mon 31 Jul to 12:31 on Tue 1 Aug, so it holds sunrise only on Tue 1 Aug, at 06:24. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Mapleton

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, 06:24 here. Chaturdashi ended at 16:22 Mon, before it. Purnima ends at 12:31, 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 Mon 31 Jul ran from sunset 20:41 Mon to sunrise 06:24, 9 h 43 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:24 to 20:40, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:40 to 06:25 Wed, splits into 8 choghadiyas of 1 h 13 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 1 at 280°. It leaves at 01:28 Wed, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 104.8° + 281.2° = 386°, one full turn and 26°. 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 07:22, 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 ended at 02:28, when the lead reached 174°; Bava runs until 12:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:24 to 06:25 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 12:31 Mon to 16 Aug 03:38 Wed the Sun stayed in Karka, entering Simha at 17 Aug 02:02 Thu, 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: 21 Mar 2023, 11:23 Tue. Since then the Sun has moved 128.2° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
