Panchang in Ipameri, Goiás, Brazil Mon 23 Oct 2056

Purnima follows the tithi at sunrise. Purnima runs from 06:45 on Sun 22 Oct to 08:46 on Mon 23 Oct, so it holds sunrise only on Mon 23 Oct, at 05:38. 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, 05:38 here. Chaturdashi ended at 06:45 Sun, before it. Purnima ends at 08:46, when the lead reaches 180°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

The night of Sun 22 Oct ran from sunset 18:15 Sun to sunrise 05:38, 11 h 23 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:38 to 18:15, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:15 to 05:37 Tue, splits into 8 choghadiyas of 1 h 25 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 2 at 3°20′. It leaves at 23:09, for Bharani.

Add the Sun's and the Moon's places among the stars: 186° + 4.6° = 190.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 23:00, then Siddhi.

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 19:44 Sun, when the lead reached 174°; Bava runs until 08:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:37 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 9 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2056, 03:52 Thu. Since then the Sun has moved 214.2° round the stars. Vikram Samvat numbers that year 2113; Shaka Samvat numbers it 1978.
