Panchang in Sevan, Gegharkunik, Armenia Sun 20 Mar 2011

Holi follows the tithi at sunrise. Pratipada runs from 22:10 on Sat 19 Mar to 18:12 on Sun 20 Mar, so it holds sunrise only on Sun 20 Mar, at 07:04.

Holi: every date in Sevan

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, 07:04 here. Purnima ended at 22:10 Sat, before it. Pratipada ends at 18:12, when the lead reaches 192°. The lead passed 180° at the full moon of 19 Mar, so the Moon is waning: Krishna paksha.

The night of Sat 19 Mar ran from sunset 19:10 Sat to sunrise 07:04, 11 h 54 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:04 to 19:11, 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, 19:11 to 07:02 Mon, splits into 8 choghadiyas of 1 h 28 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 03:12 Mon, for Chitra.

Add the Sun's and the Moon's places among the stars: 335.1° + 160.5° = 495.6°, one full turn and 135.6°. 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 23:18, then Dhruva.

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 runs until 08:10, when the lead reaches 186°; Kaulava until 18:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:04 to 07:02 Mon, so the hours after midnight still belong to Raviwara.

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, 3 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 3 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: 16 Mar 2010, 01:01 Tue. Since then the Sun has moved 363.9° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
