Panchang in Davinópolis, Maranhão, Brazil Mon 22 Jun 2043

Purnima follows the tithi at sunrise. Purnima runs from 09:36 on Sun 21 Jun to 11:20 on Mon 22 Jun, so it holds sunrise only on Mon 22 Jun, at 06:17. 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, 06:17 here. Chaturdashi ended at 09:36 Sun, before it. Purnima ends at 11:20, when the lead reaches 180°. The lead passed 0° at the new moon of 7 Jun, so the Moon is waxing: Shukla paksha.

The night of Sun 21 Jun ran from sunset 18:05 Sun to sunrise 06:17, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:17 to 18:05, 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, 18:05 to 06:17 Tue, 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 00:28 Tue, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 66.4° + 244.1° = 310.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 23:36, then Brahma.

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 22:31 Sun, when the lead reached 174°; Bava runs until 11:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:17 to 06:17 Tue, so the hours after midnight still belong to Somawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 6 Jul, finds it in Mithuna and begins Ashadha.

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 7 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2043, 16:06 Thu. Since then the Sun has moved 71° round the stars. Vikram Samvat numbers that year 2100; Shaka Samvat numbers it 1965.
