Panchang in Sevan, Gegharkunik, Armenia Sat 2 Jan 2021

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:40 on Sat 2 Jan to 06:52 on Sun 3 Jan, so it holds moonrise only on Sat 2 Jan, at 21:05. 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: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 08:23 here. Tritiya ended at 07:40, before it. Chaturthi ends at 06:52 Sun, when the lead reaches 228°. The lead passed 180° at the full moon of 30 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Fri 1 Jan ran from sunset 17:43 Fri to sunrise 08:23, 14 h 40 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:23 to 17:44, 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, 17:44 to 08:23 Sun, 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 3 at 113°20′. It leaves at 18:46, for Magha.

Add the Sun's and the Moon's places among the stars: 257.8° + 114.2° = 372°, one full turn and 12°. 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 10:32, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava runs until 19:19, when the lead reaches 222°; Balava until 06:52 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:23 to 08:23 Sun, so the hours after midnight still belong to Shaniwara.

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, 13 Jan, 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 13 Jan, 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: 24 Mar 2020, 13:28 Tue. Since then the Sun has moved 277.7° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
