Panchang in Sevan, Gegharkunik, Armenia Wed 4 Feb 1981

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 03:23 on Wed 4 Feb to 02:13 on Thu 5 Feb, so it holds sunrise only on Wed 4 Feb, at 08:06. 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, 08:06 here. Chaturdashi ended at 03:23, before it. Amavasya ends at 02:13 Thu, when the lead reaches 360°. The lead passed 180° at the full moon of 20 Jan, so the Moon is waning: Krishna paksha.

The night of Tue 3 Feb ran from sunset 18:20 Tue to sunrise 08:06, 13 h 46 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:06 to 18:21, splits into 8 choghadiyas of 1 h 16 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:21 to 08:05 Thu, splits into 8 choghadiyas of 1 h 43 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 1 at 280°. It leaves at 03:47 Thu, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 291.7° + 282.1° = 573.8°, one full turn and 213.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 05:08 Thu, then Variyana.

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 14:52, when the lead reaches 354°; Nagava until 02:13 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:06 to 08:05 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 14 Jan, inside the month. The next new moon, 5 Feb, 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 5 Feb, 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: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 318.9° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
