Panchang in Sevan, Gegharkunik, Armenia Mon 16 Sep 1974

Amavasya follows the tithi at sunrise. Amavasya runs from 10:11 on Sun 15 Sep to 06:45 on Mon 16 Sep, so it holds sunrise only on Mon 16 Sep, at 06:41. 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, 06:41 here. Chaturdashi ended at 10:11 Sun, before it. Amavasya ends at 06:45, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:45 and ended at 03:35 Tue, between the sunrises of 06:41 and 06:41 Tue. Monday reads Amavasya and Tuesday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Sun 15 Sep ran from sunset 19:09 Sun to sunrise 06:41, 11 h 32 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 19:08, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:08 to 06:41 Tue, splits into 8 choghadiyas of 1 h 26 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 1 at 146°40′. It leaves at 23:59, for Hasta.

Add the Sun's and the Moon's places among the stars: 149.4° + 149.3° = 298.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 18:48, then Shukla.

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 20:27 Sun, when the lead reached 354°; Nagava runs until 06:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:41 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 23:01 Sat to 16 Sep 06:45 the Sun stayed in Simha, entering Kanya at 16 Sep 22:33, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 16 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1974, 01:23 Sun. Since then the Sun has moved 170° round the stars. Vikram Samvat numbers that year 2031; Shaka Samvat numbers it 1896.
