Panchang in Davinópolis, Maranhão, Brazil Wed 1 Jul 2015

Purnima follows the tithi at sunrise. Purnima runs from 01:00 on Wed 1 Jul to 23:19 on Wed 1 Jul, so it holds sunrise only on Wed 1 Jul, at 06:19. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Davinópolis

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 01:00, before it. Purnima ends at 23:19, 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 18:07 Tue to sunrise 06:19, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 18:07, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 06:19 Thu, splits into 8 choghadiyas of 1 h 31 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 2 at 243°20′. It leaves at 19:00, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 75.2° + 246° = 321.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 01:57 Thu, 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 12:13, when the lead reaches 174°; Bava until 23:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:19 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 11:05 Tue to 15 Jul 22:24 Wed the Sun stayed in Mithuna, entering Karka at 16 Jul 19:32 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, 06:36 Fri. Since then the Sun has moved 99.8° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
