Panchang in Businga, Nord-Ubangi, Democratic Republic of the Congo Thu 24 Mar 2016

Holi follows the tithi at sunrise. Pratipada runs from 13:00 on Wed 23 Mar to 15:30 on Thu 24 Mar, so it holds sunrise only on Thu 24 Mar, at 05:38.

Holi: every date in Businga

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 05:38 here. Purnima ended at 13:00 Wed, before it. Pratipada ends at 15:30, when the lead reaches 192°. The lead passed 180° at the full moon of 23 Mar, so the Moon is waning: Krishna paksha.

The night of Wed 23 Mar ran from sunset 17:46 Wed to sunrise 05:38, 11 h 52 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:38 to 17:46, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:46 to 05:38 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 3 at 166°40′. It leaves at 17:36, for Chitra.

Add the Sun's and the Moon's places among the stars: 339.9° + 167.4° = 507.3°, one full turn and 147.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 05:21 Fri, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava ended at 02:14, when the lead reached 186°; Kaulava runs until 15:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:38 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 14 Mar, inside the month. The next new moon, 7 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 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 10:36 Fri. Since then the Sun has moved 364.5° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
