Panchang in Ipameri, Goiás, Brazil Wed 27 Feb 1907

Purnima follows the tithi at sunrise. Purnima runs from 02:53 on Wed 27 Feb to 03:16 on Thu 28 Feb, so it holds sunrise only on Wed 27 Feb, at 06:04. 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, 06:11 here. Chaturdashi ended at 02:59, before it. Purnima ends at 03:22 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 12 Feb, so the Moon is waxing: Shukla paksha.

The night of Tue 26 Feb ran from sunset 18:40 Tue to sunrise 06:11, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:11 to 18:40, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:40 to 06:11 Thu, splits into 8 choghadiyas of 1 h 26 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 2 at 123°20′. It leaves at 22:29, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 315.1° + 124.6° = 439.7°, one full turn and 79.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 06:40, then Sukarma.

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 15:15, when the lead reaches 174°; Bava until 03:22 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:11 to 06:11 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 12 Feb 14:42 Tue to 14 Mar 03:04 Thu the Sun stayed in Kumbha, entering Meena at 14 Mar 03:59 Thu, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna 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 12 Feb, with the Sun in Kumbha, began Phalguna (Adhik). This Shukla paksha reads Phalguna (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1906, 20:51 Sat. Since then the Sun has moved 334.2° round the stars. Vikram Samvat numbers that year 1963; Shaka Samvat numbers it 1828.
