Panchang in Sevan, Gegharkunik, Armenia Mon 15 Dec 2008

The Sankashti fast is broken at moonrise. Chaturthi runs from 09:46 on Mon 15 Dec to 06:56 on Tue 16 Dec, so it holds moonrise only on Mon 15 Dec, at 20:49. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 08:16 here. Dwitiya ended at 13:05 Sun, before it. Tritiya ends at 09:46, when the lead reaches 216°. The lead passed 180° at the full moon of 12 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 09:46 and ended at 06:56 Tue, between the sunrises of 08:16 and 08:17 Tue. Monday reads Tritiya and Tuesday reads Panchami: Chaturthi is a kshaya tithi here.

The night of Sun 14 Dec ran from sunset 17:33 Sun to sunrise 08:16, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:16 to 17:34, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:34 to 08:17 Tue, splits into 8 choghadiyas of 1 h 50 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 03:50 Tue, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 239.6° + 94.7° = 334.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 03:12 Tue, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija ended at 23:22 Sun, when the lead reached 210°; Vishti runs until 09:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:16 to 08:17 Tue, so the hours after midnight still belong to Somawara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 27 Dec, finds it in Dhanu and begins Pausha.

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 27 Dec, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 2008, 08:55 Sun. Since then the Sun has moved 246.8° round the stars. Vikram Samvat numbers that year 2065; Shaka Samvat numbers it 1930.
