Panchang in Pāthardi, Maharashtra Thu 21 Mar 2019

Holi follows the tithi at sunrise. Pratipada begins at 07:12 on Thu 21 Mar, after that sunrise, and ends at 03:52 on Fri 22 Mar, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 21 Mar.

Holi: every date in Pāthardi

Purnima follows the tithi at sunrise. Purnima runs from 10:45 on Wed 20 Mar to 07:12 on Thu 21 Mar, so it holds sunrise only on Thu 21 Mar, at 06:33. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Pāthardi

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, 06:33 here. Chaturdashi ended at 10:45 Wed, before it. Purnima ends at 07:12, when the lead reaches 180°. The lead passed 0° at the new moon of 6 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 07:12 and ended at 03:52 Fri, between the sunrises of 06:33 and 06:32 Fri. Thursday reads Purnima and Friday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Wed 20 Mar ran from sunset 18:40 Wed to sunrise 06:33, 11 h 53 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:33 to 18:40, 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, 18:40 to 06:32 Fri, 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 3 at 153°20′. It leaves at 13:33, for Hasta.

Add the Sun's and the Moon's places among the stars: 336° + 155.6° = 491.6°, one full turn and 131.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 09:06, then Vriddhi.

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 20:58 Wed, when the lead reached 174°; Bava runs until 07:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:33 to 06:32 Fri, so the hours after midnight still belong to Guruwara.

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 15 Mar, inside the month. The next new moon, 5 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 6 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: 17 Mar 2018, 18:41 Sat. Since then the Sun has moved 363.2° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
