Panchang in Mapleton, Utah, United States Wed 1 Jul 2015

Purnima follows the tithi at sunrise. Purnima runs from 22:00 on Tue 30 Jun to 20:19 on Wed 1 Jul, so it holds sunrise only on Wed 1 Jul, at 06:00. 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, 06:00 here. Chaturdashi ended at 22:00 Tue, before it. Purnima ends at 20:19, when the lead reaches 180°. The lead passed 0° at the new moon of 16 Jun, so the Moon is waxing: Shukla paksha.

The night of Tue 30 Jun ran from sunset 20:59 Tue to sunrise 06:00, 9 h 1 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:00 to 20:59, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:59 to 06:01 Thu, splits into 8 choghadiyas of 1 h 7 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 3 at 246°40′. It leaves at 16:00, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 75.3° + 247.6° = 322.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 22:57, then Indra.

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 09:13, when the lead reaches 174°; Bava until 20:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:00 to 06:01 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 Jun 08:05 Tue to 15 Jul 19:24 Wed the Sun stayed in Mithuna, entering Karka at 16 Jul 16:32 Thu, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 Jun, with the Sun in Mithuna, began Ashadha (Adhik). This Shukla paksha reads Ashadha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 03:36 Fri. Since then the Sun has moved 99.9° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
