Panchang in Sevan, Gegharkunik, Armenia Tue 14 May 1991

Amavasya follows the tithi at sunrise. Amavasya runs from 11:43 on Mon 13 May to 08:35 on Tue 14 May, so it holds sunrise only on Tue 14 May, at 05:45. 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, 05:45 here. Chaturdashi ended at 11:43 Mon, before it. Amavasya ends at 08:35, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:35 and ended at 05:14 Wed, between the sunrises of 05:45 and 05:44 Wed. Tuesday reads Amavasya and Wednesday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Mon 13 May ran from sunset 20:07 Mon to sunrise 05:45, 9 h 38 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:45 to 20:08, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:08 to 05:44 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Krittika spans 26°40′–40°00′; the Moon entered its pada 1 at 26°40′. It leaves at 02:02 Wed, for Rohini.

Add the Sun's and the Moon's places among the stars: 29° + 27.4° = 56.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 21:12, then Atiganda.

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 22:12 Mon, when the lead reached 354°; Nagava runs until 08:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:45 to 05:44 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 23:37 Sun to 14 May 08:35 the Sun stayed in Mesha, entering Vrishabha at 15 May 05:25 Wed, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha itself.

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 14 May, with the Sun in Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1991, 12:10 Sat. Since then the Sun has moved 57.5° round the stars. Vikram Samvat numbers that year 2048; Shaka Samvat numbers it 1913.
