Panchang in Sevan, Gegharkunik, Armenia Fri 15 Aug 1958

Amavasya follows the tithi at sunrise. Amavasya runs from 09:59 on Thu 14 Aug to 07:33 on Fri 15 Aug, so it holds sunrise only on Fri 15 Aug, at 06:09. 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, 06:09 here. Chaturdashi ended at 09:59 Thu, before it. Amavasya ends at 07:33, when the lead reaches 360°. The lead passed 180° at the full moon of 30 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 07:33 and ended at 04:47 Sat, between the sunrises of 06:09 and 06:10 Sat. Friday reads Amavasya and Saturday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Thu 14 Aug ran from sunset 19:59 Thu to sunrise 06:09, 10 h 10 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 19:58, 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, 19:58 to 06:10 Sat, 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 09:59, for Magha.

Add the Sun's and the Moon's places among the stars: 118.5° + 117.7° = 236.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 12:08, 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 20:49 Thu, when the lead reached 354°; Nagava runs until 07:33.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:10 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 Jul 22:33 Wed to 15 Aug 07:33 the Sun stayed in Karka, entering Simha at 16 Aug 20:17 Sat, 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 15 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 1958, 13:49 Thu. Since then the Sun has moved 142.5° round the stars. Vikram Samvat numbers that year 2015; Shaka Samvat numbers it 1880.
