Panchang in Sevan, Gegharkunik, Armenia Sat 13 Jun 2037

Amavasya follows the tithi at sunrise. Amavasya runs from 22:08 on Fri 12 Jun to 21:10 on Sat 13 Jun, so it holds sunrise only on Sat 13 Jun, at 05:28. 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, 05:28 here. Chaturdashi ended at 22:08 Fri, before it. Amavasya ends at 21:10, when the lead reaches 360°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Fri 12 Jun ran from sunset 20:31 Fri to sunrise 05:28, 8 h 57 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:28 to 20:31, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:31 to 05:28 Sun, splits into 8 choghadiyas of 1 h 7 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 3 at 46°40′. It leaves at 11:44, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 58° + 49.8° = 107.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 01:36 Sun, 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 09:43, when the lead reaches 354°; Nagava until 21:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:28 to 05:28 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 09:54 Fri to 13 Jun 21:10 the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 07:02 Mon, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 13 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2037, 03:36 Tue. Since then the Sun has moved 85.7° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
