Panchang in Sevan, Gegharkunik, Armenia Tue 5 Dec 1972

Amavasya follows the tithi at sunrise. Amavasya runs from 21:46 on Mon 4 Dec to 00:24 on Wed 6 Dec, so it holds sunrise only on Tue 5 Dec, at 08:07. 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, 08:07 here. Chaturdashi ended at 21:46 Mon, before it. Amavasya ends at 00:24 Wed, when the lead reaches 360°. The lead passed 180° at the full moon of 21 Nov, so the Moon is waning: Krishna paksha.

The night of Mon 4 Dec ran from sunset 17:33 Mon to sunrise 08:07, 14 h 34 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:07 to 17:33, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:33 to 08:08 Wed, splits into 8 choghadiyas of 1 h 49 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 3 at 220°. It leaves at 16:57, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 229.6° + 222.3° = 451.9°, one full turn and 91.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 10:41, then Dhriti.

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 runs until 11:05, when the lead reaches 354°; Nagava until 00:24 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:07 to 08:08 Wed, so the hours after midnight still belong to Mangalawara.

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: Tula gives Kartika. The Sun enters Vrishchika on 15 Nov, inside the month. The next new moon, 6 Dec, finds it in Vrishchika and begins Margashirsha.

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 6 Dec, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 15:34 Wed. Since then the Sun has moved 258.1° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
