Panchang in Sevan, Gegharkunik, Armenia Sat 14 Aug 1920

Amavasya follows the tithi at sunrise. Amavasya runs from 09:51 on Fri 13 Aug to 06:41 on Sat 14 Aug, so it holds sunrise only on Sat 14 Aug, at 05:06. 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, 05:08 here. Chaturdashi ended at 09:53 Fri, before it. Amavasya ends at 06:43, when the lead reaches 360°. The lead passed 180° at the full moon of 31 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:43 and ended at 03:52 Sun, between the sunrises of 05:08 and 05:09 Sun. Saturday reads Amavasya and Sunday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Fri 13 Aug ran from sunset 19:00 Fri to sunrise 05:08, 10 h 8 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:08 to 18:59, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:59 to 05:09 Sun, splits into 8 choghadiyas of 1 h 16 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 4 at 116°40′. It leaves at 09:32, for Magha.

Add the Sun's and the Moon's places among the stars: 118.2° + 117.3° = 235.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 12:00, then Parigha.

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 20:16 Fri, when the lead reached 354°; Nagava runs until 06:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:08 to 05:09 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Jul 23:24 Thu to 14 Aug 06:43 the Sun stayed in Karka, entering Simha at 16 Aug 01:42 Mon, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1920, 13:55 Sat. Since then the Sun has moved 141.4° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
