Panchang in Ipameri, Goiás, Brazil Mon 1 Sep 2031

Purnima follows the tithi at sunrise. Purnima runs from 09:33 on Sun 31 Aug to 06:20 on Mon 1 Sep, so it holds sunrise only on Mon 1 Sep, at 06:20. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Ipameri

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, 06:20 here. Chaturdashi ended at 09:33 Sun, before it. Purnima ends at 06:20, when the lead reaches 180°. The lead passed 0° at the new moon of 18 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:20 and ended at 03:27 Tue, between the sunrises of 06:20 and 06:19 Tue. Monday reads Purnima and Tuesday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Sun 31 Aug ran from sunset 18:05 Sun to sunrise 06:20, 12 h 15 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 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 06:19 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 3 at 313°20′. It leaves at 15:23, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 134.5° + 314.5° = 449°, one full turn and 89°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 13:05, then Dhriti.

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 19:55 Sun, when the lead reached 174°; Bava runs until 06:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:19 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Aug 01:32 Mon to 16 Sep 15:46 Tue the Sun stayed in Simha, entering Kanya at 17 Sep 06:19 Wed, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 18 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 00:49 Sun. Since then the Sun has moved 156.5° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
