Panchang in Sevan, Gegharkunik, Armenia Tue 31 Mar 1964

The Sankashti fast is broken at moonrise. Chaturthi runs from 10:45 on Tue 31 Mar to 12:59 on Wed 1 Apr, so it holds moonrise only on Tue 31 Mar, at 22:41. 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, 06:45 here. Dwitiya ended at 08:56 Mon, before it. Tritiya ends at 10:45, when the lead reaches 216°. The lead passed 180° at the full moon of 28 Mar, so the Moon is waning: Krishna paksha.

The night of Mon 30 Mar ran from sunset 19:22 Mon to sunrise 06:45, 11 h 23 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:45 to 19:23, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:23 to 06:44 Wed, splits into 8 choghadiyas of 1 h 25 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 1 at 200°. It leaves at 06:59 Wed, for Anuradha.

Add the Sun's and the Moon's places among the stars: 347.1° + 201.2° = 548.3°, one full turn and 188.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 04:23 Wed, then Siddhi.

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 21:47 Mon, when the lead reached 210°; Vishti runs until 10:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:45 to 06:44 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 06:13 Sat to 12 Apr 16:37 Sun the Sun stayed in Meena, entering Mesha at 13 Apr 10:22 Mon, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra itself.

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 12 Apr, with the Sun in Meena, begins Chaitra (Adhik). Until then this Krishna paksha reads Chaitra (Adhik) here, and Chaitra (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 1964, 06:13 Sat. Since then the Sun has moved 16.9° round the stars. Vikram Samvat numbers that year 2021; Shaka Samvat numbers it 1886.
