Panchang in Ipameri, Goiás, Brazil Sat 26 Feb 1983

Purnima follows the tithi at sunrise. Purnima begins at 09:21 on Sat 26 Feb, after that sunrise, and ends at 05:58 on Sun 27 Feb, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sat 26 Feb. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:10 here. Trayodashi ended at 12:48 Fri, before it. Chaturdashi ends at 09:21, when the lead reaches 168°. The lead passed 0° at the new moon of 12 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 09:21 and ended at 05:58 Sun, between the sunrises of 06:10 and 06:11 Sun. Saturday reads Chaturdashi and Sunday reads Pratipada: Purnima is a kshaya tithi here.

The night of Fri 25 Feb ran from sunset 18:41 Fri to sunrise 06:10, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 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 Sun, 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 06:36, for Magha.

Add the Sun's and the Moon's places among the stars: 313.6° + 119.7° = 433.3°, one full turn and 73.3°. 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 16:12, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 23:05 Fri, when the lead reached 162°; Vanija runs until 09:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:11 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 12 Feb 21:31 Sat to 14 Mar 14:43 Mon the Sun stayed in Kumbha, entering Meena at 14 Mar 15:44 Mon, 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: 25 Mar 1982, 07:17 Thu. Since then the Sun has moved 332.8° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
