Panchang in Sevan, Gegharkunik, Armenia Sun 24 Oct 1965

Amavasya follows the tithi at sunrise. Amavasya runs from 19:53 on Sat 23 Oct to 18:11 on Sun 24 Oct, so it holds sunrise only on Sun 24 Oct, at 07:20. 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, 07:20 here. Chaturdashi ended at 19:53 Sat, before it. Amavasya ends at 18:11, when the lead reaches 360°. The lead passed 180° at the full moon of 10 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 23 Oct ran from sunset 18:09 Sat to sunrise 07:20, 13 h 11 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:20 to 18:07, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 07:21 Mon, splits into 8 choghadiyas of 1 h 39 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 16:35, for Swati.

Add the Sun's and the Moon's places among the stars: 187.1° + 181.3° = 368.4°, one full turn and 8.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 15:13, then Priti.

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 06:58, when the lead reached 354°; Nagava runs until 18:11.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:20 to 07:21 Mon, so the hours after midnight still belong to Raviwara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 24 Oct, finds it in Tula and begins Kartika.

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 24 Oct, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 2 Apr 1965, 04:20 Fri. Since then the Sun has moved 198.4° round the stars. Vikram Samvat numbers that year 2022; Shaka Samvat numbers it 1887.
