Panchang in Sevan, Gegharkunik, Armenia Thu 4 Jan 2018

The Sankashti fast is broken at moonrise. Chaturthi runs from 20:01 on Thu 4 Jan to 17:30 on Fri 5 Jan, so it holds moonrise only on Thu 4 Jan, at 20:43. 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, 08:23 here. Dwitiya ended at 23:07 Wed, before it. Tritiya ends at 20:01, when the lead reaches 216°. The lead passed 180° at the full moon of 2 Jan, so the Moon is waning: Krishna paksha.

The night of Wed 3 Jan ran from sunset 17:45 Wed to sunrise 08:23, 14 h 38 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:23 to 17:46, splits into 8 choghadiyas of 1 h 10 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 08:23 Fri, splits into 8 choghadiyas of 1 h 49 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 02:23 Fri, for Magha.

Add the Sun's and the Moon's places among the stars: 259.6° + 109° = 368.6°, one full turn and 8.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 15:31, then Priti.

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 09:31, when the lead reaches 210°; Vishti until 20:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:23 to 08:23 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 17 Jan, finds it in Makara and begins Magha.

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 17 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 06:57 Tue. Since then the Sun has moved 276.1° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
