Panchang in Sevan, Gegharkunik, Armenia Sun 18 Feb 2091

Amavasya follows the tithi at sunrise. Amavasya runs from 12:06 on Sat 17 Feb to 13:40 on Sun 18 Feb, so it holds sunrise only on Sun 18 Feb, at 07:49. 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, 07:49 here. Chaturdashi ended at 12:06 Sat, before it. Amavasya ends at 13:40, when the lead reaches 360°. The lead passed 180° at the full moon of 4 Feb, so the Moon is waning: Krishna paksha.

The night of Sat 17 Feb ran from sunset 18:37 Sat to sunrise 07:49, 13 h 12 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:49 to 18:38, splits into 8 choghadiyas of 1 h 21 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:38 to 07:48 Mon, splits into 8 choghadiyas of 1 h 38 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 3 at 300°. It leaves at 17:15, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 304.6° + 301.9° = 606.5°, one full turn and 246.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 20:17, then Shiva.

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 00:50, when the lead reached 354°; Nagava runs until 13:40.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:49 to 07:48 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 18 Feb, finds it in Kumbha and begins Phalguna.

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 18 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 2090, 07:49 Fri. Since then the Sun has moved 318.8° round the stars. Vikram Samvat numbers that year 2147; Shaka Samvat numbers it 2012.
