Panchang in Sevan, Gegharkunik, Armenia Sat 16 Nov 1963

Amavasya follows the tithi at sunrise. Amavasya runs from 08:16 on Fri 15 Nov to 10:50 on Sat 16 Nov, so it holds sunrise only on Sat 16 Nov, at 07:46. 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, 07:46 here. Chaturdashi ended at 08:16 Fri, before it. Amavasya ends at 10:50, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Nov, so the Moon is waning: Krishna paksha.

The night of Fri 15 Nov ran from sunset 17:43 Fri to sunrise 07:46, 14 h 3 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:46 to 17:42, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:42 to 07:47 Sun, splits into 8 choghadiyas of 1 h 45 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 3 at 206°40′. It leaves at 17:55, for Anuradha.

Add the Sun's and the Moon's places among the stars: 209.7° + 208.3° = 418°, one full turn and 58°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 23:54, then Atiganda.

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 21:32 Fri, when the lead reached 354°; Nagava runs until 10:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:46 to 07:47 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 17 Oct 16:42 Thu to 16 Nov 10:50 the Sun stayed in Tula, entering Vrishchika at 16 Nov 14:39, after the new moon. A month with no sankranti is Adhika Kartika, before Kartika 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 Nov, with the Sun in Tula, begins Kartika (Adhik). Until then this Krishna paksha reads Kartika (Adhik) here, and Kartika (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1963, 16:09 Mon. Since then the Sun has moved 228.9° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
