Panchang in Sevan, Gegharkunik, Armenia Tue 16 May 1950

Vat Savitri Vrat follows the tithi at sunrise. Amavasya runs from 01:24 on Tue 16 May to 03:54 on Wed 17 May, so it holds sunrise only on Tue 16 May, at 04:43. No text giving Vat Savitri Vrat’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, 04:43 here. Chaturdashi ended at 01:24, before it. Amavasya ends at 03:54 Wed, when the lead reaches 360°. The lead passed 180° at the full moon of 2 May, so the Moon is waning: Krishna paksha.

The night of Mon 15 May ran from sunset 19:08 Mon to sunrise 04:43, 9 h 35 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:43 to 19:09, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:09 to 04:42 Wed, splits into 8 choghadiyas of 1 h 11 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 3 at 20°. It leaves at 16:17, for Krittika.

Add the Sun's and the Moon's places among the stars: 31.5° + 21° = 52.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 06:24, then Shobhana.

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 14:40, when the lead reaches 354°; Nagava until 03:54 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:43 to 04:42 Wed, so the hours after midnight still belong to Mangalawara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 17 May, finds it in Vrishabha and begins Jyeshtha.

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 17 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 18:20 Sat. Since then the Sun has moved 57.2° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
