Panchang in Sevan, Gegharkunik, Armenia Sun 9 Mar 1902

Amavasya follows the tithi at sunrise. Amavasya begins at 07:15 on Sun 9 Mar, after that sunrise, and ends at 05:48 on Mon 10 Mar, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sun 9 Mar. 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:23 here. Trayodashi ended at 08:13 Sat, before it. Chaturdashi ends at 07:17, when the lead reaches 348°. The lead passed 180° at the full moon of 22 Feb, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 07:17 and ended at 05:50 Mon, between the sunrises of 06:23 and 06:21 Mon. Sunday reads Chaturdashi and Monday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Sat 8 Mar ran from sunset 17:58 Sat to sunrise 06:23, 12 h 25 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:23 to 17:59, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:59 to 06:21 Mon, splits into 8 choghadiyas of 1 h 32 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 2 at 310°. It leaves at 19:13, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 325.1° + 312.7° = 637.8°, one full turn and 277.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 09:58, then Sadhya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 19:50 Sat, when the lead reached 342°; Shakuni runs until 07:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:23 to 06:21 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 12 Feb, inside the month. The next new moon, 10 Mar, 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 10 Mar, 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: 20 Mar 1901, 15:52 Wed. Since then the Sun has moved 348.3° round the stars. Vikram Samvat numbers that year 1958; Shaka Samvat numbers it 1823.
