Panchang in Sevan, Gegharkunik, Armenia Sun 28 Feb 2010

Holika is burnt in pradosha, the 3 muhurtas after sunset, outside bhadra. Purnima runs from 00:20 on Sun 28 Feb to 20:37 on Sun 28 Feb, so it touches only Sunday’s pradosha (18:49–21:22).

Holika Dahan: every date in Sevan

Purnima follows the tithi at sunrise. Purnima runs from 00:20 on Sun 28 Feb to 20:37 on Sun 28 Feb, so it holds sunrise only on Sun 28 Feb, at 07:35. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Sevan

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, 07:35 here. Chaturdashi ended at 00:20, before it. Purnima ends at 20:37, when the lead reaches 180°. The lead passed 0° at the new moon of 14 Feb, so the Moon is waxing: Shukla paksha.

The night of Sat 27 Feb ran from sunset 18:48 Sat to sunrise 07:35, 12 h 47 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:35 to 18:49, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:49 to 07:34 Mon, splits into 8 choghadiyas of 1 h 35 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 16:27, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 315.4° + 127.7° = 443.1°, one full turn and 83.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 22:40, then Dhriti.

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 runs until 10:29, when the lead reaches 174°; Bava until 20:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:35 to 07:34 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 14 Mar, inside the month. The next new moon, 16 Mar, 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 14 Feb, 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: 26 Mar 2009, 20:05 Thu. Since then the Sun has moved 333.3° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
