Panchang in Sevan, Gegharkunik, Armenia Wed 7 May 1902

Amavasya follows the tithi at sunrise. Amavasya begins at 05:08 on Wed 7 May, after that sunrise, and ends at 01:43 on Thu 8 May, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 7 May. 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, 04:53 here. Trayodashi ended at 08:16 Tue, before it. Chaturdashi ends at 05:10, when the lead reaches 348°. The lead passed 180° at the full moon of 22 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 05:10 and ended at 01:45 Thu, between the sunrises of 04:53 and 04:51 Thu. Wednesday reads Chaturdashi and Thursday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Tue 6 May ran from sunset 18:59 Tue to sunrise 04:53, 9 h 54 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:53 to 19:00, splits into 8 choghadiyas of 1 h 45 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:00 to 04:51 Thu, splits into 8 choghadiyas of 1 h 13 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 08:47, for Bharani.

Add the Sun's and the Moon's places among the stars: 23.1° + 10.9° = 34°. The sum, cut into 27 parts of 13°20′, gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 13:58, then Saubhagya.

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 18:46 Tue, when the lead reached 342°; Shakuni runs until 05:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:53 to 04:51 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 8 May, finds it in Mesha and begins Vaishakha.

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 8 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 1902, 16:49 Tue. Since then the Sun has moved 27.8° round the stars. Vikram Samvat numbers that year 1959; Shaka Samvat numbers it 1824.
