Panchang in Sevan, Gegharkunik, Armenia Thu 14 Jun 1923

Amavasya follows the tithi at sunrise. Amavasya runs from 14:30 on Wed 13 Jun to 15:39 on Thu 14 Jun, so it holds sunrise only on Thu 14 Jun, at 04:26. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 04:28 here. Chaturdashi ended at 14:32 Wed, before it. Amavasya ends at 15:41, when the lead reaches 360°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

The night of Wed 13 Jun ran from sunset 19:30 Wed to sunrise 04:28, 8 h 58 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:28 to 19:31, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:31 to 04:28 Fri, splits into 8 choghadiyas of 1 h 7 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 05:07 Fri, for Ardra.

Add the Sun's and the Moon's places among the stars: 59.2° + 53.8° = 113°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 16:58, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 03:10, when the lead reached 354°; Nagava runs until 15:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:28 to 04:28 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 May 01:38 Wed to 14 Jun 15:41 the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 00:42 Fri, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 14 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1923, 15:51 Sat. Since then the Sun has moved 86.1° round the stars. Vikram Samvat numbers that year 1980; Shaka Samvat numbers it 1845.
