Panchang in Sevan, Gegharkunik, Armenia Thu 13 Apr 1933

The Sun enters Mesha at 10:39, between sunrise (05:25) and sunset (18:36): Thu 13 Apr. No text giving Mesha Sankranti’s time was found; sankranti is Tithika’s convention.

Mesha Sankranti: every date in Sevan

The Sankashti fast is broken at moonrise. Chaturthi runs from 06:53 on Thu 13 Apr to 03:40 on Fri 14 Apr, so it holds moonrise only on Thu 13 Apr, at 22:40. 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, 05:25 here. Dwitiya ended at 10:13 Wed, before it. Tritiya ends at 06:53, when the lead reaches 216°. The lead passed 180° at the full moon of 10 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 06:53 and ended at 03:40 Fri, between the sunrises of 05:25 and 05:24 Fri. Thursday reads Tritiya and Friday reads Panchami: Chaturthi is a kshaya tithi here.

The night of Wed 12 Apr ran from sunset 18:35 Wed to sunrise 05:25, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 18:36, 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, 18:36 to 05:24 Fri, 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 1 at 213°20′. It leaves at 00:23 Fri, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 359.8° + 214.9° = 574.7°, one full turn and 214.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 23:31, then Variyana.

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 20:32 Wed, when the lead reached 210°; Vishti runs until 06:53.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:24 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 24 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 24 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 1933, 06:20 Sun. Since then the Sun has moved 17.7° round the stars. Vikram Samvat numbers that year 1990; Shaka Samvat numbers it 1855.
