Panchang in Sevan, Gegharkunik, Armenia Fri 15 Jan 2010

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 08:42 on Thu 14 Jan to 11:11 on Fri 15 Jan, so it holds sunrise only on Fri 15 Jan, at 08:21. 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, 08:21 here. Chaturdashi ended at 08:42 Thu, before it. Amavasya ends at 11:11, when the lead reaches 360°. The lead passed 180° at the full moon of 31 Dec, so the Moon is waning: Krishna paksha.

The night of Thu 14 Jan ran from sunset 17:56 Thu to sunrise 08:21, 14 h 25 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:21 to 17:57, splits into 8 choghadiyas of 1 h 12 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:57 to 08:21 Sat, splits into 8 choghadiyas of 1 h 48 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 1 at 266°40′. It leaves at 05:24 Sat, for Shravana.

Add the Sun's and the Moon's places among the stars: 270.9° + 269.6° = 540.5°, one full turn and 180.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 19:49, then Vajra.

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 21:55 Thu, when the lead reached 354°; Nagava runs until 11:11.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:21 to 08:21 Sat, so the hours after midnight still belong to Shukrawara.

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, 15 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 15 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: 26 Mar 2009, 20:05 Thu. Since then the Sun has moved 288.8° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
