Panchang in Sevan, Gegharkunik, Armenia Tue 23 Apr 1963

Amavasya follows the tithi at sunrise. Amavasya runs from 04:25 on Tue 23 Apr to 00:28 on Wed 24 Apr, so it holds sunrise only on Tue 23 Apr, at 06:11. 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, 06:11 here. Chaturdashi ended at 04:25, before it. Amavasya ends at 00:28 Wed, when the lead reaches 360°. The lead passed 180° at the full moon of 9 Apr, so the Moon is waning: Krishna paksha.

Sunrise here, 05:48, came before Chaturdashi ended at 05:55: this day reads Chaturdashi. Amavasya ends at 01:58 Wed, before the next sunrise, so no day here reads Amavasya: it is kshaya.

Sunrise here, 06:11, came after Chaturdashi ended at 04:25: this day reads Amavasya.

The night of Mon 22 Apr ran from sunset 19:45 Mon to sunrise 06:11, 10 h 26 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:11 to 19:46, splits into 8 choghadiyas of 1 h 41 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:46 to 06:09 Wed, splits into 8 choghadiyas of 1 h 17 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 09:25, for Ashwini.

Add the Sun's and the Moon's places among the stars: 8.9° + 357.9° = 366.8°, one full turn and 6.8°. 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 15:47, 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 runs until 14:27, when the lead reaches 354°; Nagava until 00:28 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:11 to 06:09 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 24 Apr, finds it in Mesha and begins Vaishakha.

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 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra 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 28.1° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
