Panchang in Sevan, Gegharkunik, Armenia Tue 19 May 1992

The Sankashti fast is broken at moonrise. Chaturthi runs from 21:56 on Tue 19 May to 23:42 on Wed 20 May, touching moonrise on both nights. When it does, the Dharmasindhu takes the earlier day: Tue 19 May. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 05:39 here. Dwitiya ended at 20:43 Mon, before it. Tritiya ends at 21:56, when the lead reaches 216°. The lead passed 180° at the full moon of 16 May, so the Moon is waning: Krishna paksha.

The night of Mon 18 May ran from sunset 20:12 Mon to sunrise 05:39, 9 h 27 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:39 to 20:13, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:13 to 05:39 Wed, splits into 8 choghadiyas of 1 h 10 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 02:03 Wed, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 34.6° + 242.9° = 277.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 10:15, then Sadhya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija runs until 09:15, when the lead reaches 210°; Vishti until 21:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:39 to 05:39 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, 1 Jun, 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 1 Jun, 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: 3 Apr 1992, 09:01 Fri. Since then the Sun has moved 44.7° round the stars. Vikram Samvat numbers that year 2049; Shaka Samvat numbers it 1914.
