Panchang in Sevan, Gegharkunik, Armenia Sun 12 Apr 2009

The Sankashti fast is broken at moonrise. Chaturthi runs from 20:49 on Sun 12 Apr to 22:18 on Mon 13 Apr, so it holds moonrise only on Sun 12 Apr, at 23:57. 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, 07:26 here. Dwitiya ended at 19:56 Sat, before it. Tritiya ends at 20:49, when the lead reaches 216°. The lead passed 180° at the full moon of 9 Apr, so the Moon is waning: Krishna paksha.

The night of Sat 11 Apr ran from sunset 20:34 Sat to sunrise 07:26, 10 h 52 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:26 to 20:35, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:35 to 07:24 Mon, splits into 8 choghadiyas of 1 h 21 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 3 at 206°40′. It leaves at 17:50, for Anuradha.

Add the Sun's and the Moon's places among the stars: 358.3° + 207.9° = 566.2°, one full turn and 206.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 20:03, then Vyatipata.

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 runs until 08:18, when the lead reaches 210°; Vishti until 20:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:26 to 07:24 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 25 Apr, finds it in Mesha and begins Vaishakha.

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 25 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

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 16.2° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
