Panchang in Ipameri, Goiás, Brazil Wed 27 Mar 2013

Holi follows the tithi at sunrise. Pratipada begins at 06:27 on Wed 27 Mar, after that sunrise, and ends at 04:35 on Thu 28 Mar, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 27 Mar.

Holi: every date in Ipameri

Purnima follows the tithi at sunrise. Purnima runs from 07:54 on Tue 26 Mar to 06:27 on Wed 27 Mar, so it holds sunrise only on Wed 27 Mar, at 06:18. 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, 06:18 here. Chaturdashi ended at 07:54 Tue, before it. Purnima ends at 06:27, when the lead reaches 180°. The lead passed 0° at the new moon of 11 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:27 and ended at 04:35 Thu, between the sunrises of 06:18 and 06:18 Thu. Wednesday reads Purnima and Thursday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Tue 26 Mar ran from sunset 18:18 Tue to sunrise 06:18, 12 h 0 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:17, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 06:18 Thu, splits into 8 choghadiyas of 1 h 30 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 00:28 Thu, for Chitra.

Add the Sun's and the Moon's places among the stars: 342.8° + 162.7° = 505.5°, one full turn and 145.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 08:04, then Dhruva.

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 19:14 Tue, when the lead reached 174°; Bava runs until 06:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:18 Thu, so the hours after midnight still belong to Budhawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 10 Apr, finds it in Meena and begins Chaitra.

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 11 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 11:37 Thu. Since then the Sun has moved 364.5° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
