Panchang in Ipameri, Goiás, Brazil Fri 23 Mar 1951

Holi follows the tithi at sunrise. Pratipada begins at 08:49 on Fri 23 Mar, after that sunrise, and ends at 07:03 on Sat 24 Mar, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Fri 23 Mar.

Holi: every date in Ipameri

Purnima follows the tithi at sunrise. Purnima runs from 10:06 on Thu 22 Mar to 08:49 on Fri 23 Mar, so it holds sunrise only on Fri 23 Mar, at 07:17. 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, 07:17 here. Chaturdashi ended at 10:06 Thu, before it. Purnima ends at 08:49, when the lead reaches 180°. The lead passed 0° at the new moon of 7 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:49 and ended at 07:03 Sat, between the sunrises of 07:17 and 07:17 Sat. Friday reads Purnima and Saturday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Thu 22 Mar ran from sunset 19:22 Thu to sunrise 07:17, 11 h 55 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:17 to 19:21, 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 night here, 19:21 to 07:17 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 10:52, for Hasta.

Add the Sun's and the Moon's places among the stars: 338.8° + 157.9° = 496.7°, one full turn and 136.7°. 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 23:21, 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 21:32 Thu, when the lead reached 174°; Bava runs until 08:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:17 to 07:17 Sat, so the hours after midnight still belong to Shukrawara.

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, 6 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 7 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: 18 Mar 1950, 13:20 Sat. Since then the Sun has moved 364.5° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
