Panchang in Sevan, Gegharkunik, Armenia Wed 30 Jan 1957

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 21:54 on Tue 29 Jan to 00:24 on Thu 31 Jan, so it holds sunrise only on Wed 30 Jan, at 07:11. No text giving Mauni 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, 07:11 here. Chaturdashi ended at 21:54 Tue, before it. Amavasya ends at 00:24 Thu, when the lead reaches 360°. The lead passed 180° at the full moon of 16 Jan, so the Moon is waning: Krishna paksha.

The night of Tue 29 Jan ran from sunset 17:13 Tue to sunrise 07:11, 13 h 58 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:11 to 17:15, splits into 8 choghadiyas of 1 h 15 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:15 to 07:11 Thu, splits into 8 choghadiyas of 1 h 44 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 09:16, for Shravana.

Add the Sun's and the Moon's places among the stars: 286.8° + 279° = 565.8°, one full turn and 205.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 21:21, then Vyatipata.

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 11:09, when the lead reaches 354°; Nagava until 00:24 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:11 to 07:11 Thu, so the hours after midnight still belong to Budhawara.

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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 31 Jan, finds it in Makara and begins Magha.

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 31 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1956, 05:38 Wed. Since then the Sun has moved 288.9° round the stars. Vikram Samvat numbers that year 2013; Shaka Samvat numbers it 1878.
