Panchang in Sevan, Gegharkunik, Armenia Sun 21 Dec 2014

Amavasya follows the tithi at sunrise. Amavasya runs from 07:46 on Sun 21 Dec to 05:35 on Mon 22 Dec, so it holds sunrise only on Sun 21 Dec, at 08:19. 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, 08:19 here. Chaturdashi ended at 07:46, before it. Amavasya ends at 05:35 Mon, when the lead reaches 360°. The lead passed 180° at the full moon of 6 Dec, so the Moon is waning: Krishna paksha.

Sunrise here, 07:09, came before Chaturdashi ended at 09:16: this day reads Chaturdashi. Amavasya ends at 07:05 Mon, before the next sunrise, so no day here reads Amavasya: it is kshaya.

The night of Sat 20 Dec ran from sunset 17:35 Sat to sunrise 08:19, 14 h 44 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:19 to 17:36, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:36 to 08:20 Mon, splits into 8 choghadiyas of 1 h 50 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 3 at 233°20′. It leaves at 19:27, for Mula.

Add the Sun's and the Moon's places among the stars: 245.1° + 233.4° = 478.5°, one full turn and 118.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 10:35, then Ganda.

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 18:44, when the lead reaches 354°; Nagava until 05:35 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:19 to 08:20 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 22 Dec, finds it in Dhanu and begins Pausha.

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 22 Dec, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 2014, 22:44 Sun. Since then the Sun has moved 259.2° round the stars. Vikram Samvat numbers that year 2071; Shaka Samvat numbers it 1936.
