Panchang in Sevan, Gegharkunik, Armenia Wed 31 Oct 1973

The evening arghya is offered at sunset. Shashthi runs from 16:04 on Wed 31 Oct to 18:47 on Thu 1 Nov, holding as much of sunset on both evenings. The Nirnayasindhu then takes the earlier: Wed 31 Oct. No text giving Chhath · Sandhya Arghya’s time was found; sunset is Tithika’s convention.

Chhath: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 07:28 here. Chaturthi ended at 13:27 Tue, before it. Panchami ends at 16:04, when the lead reaches 60°. The lead passed 0° at the new moon of 26 Oct, so the Moon is waxing: Shukla paksha.

The night of Tue 30 Oct ran from sunset 17:59 Tue to sunrise 07:28, 13 h 29 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:28 to 17:58, splits into 8 choghadiyas of 1 h 18 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:58 to 07:29 Thu, splits into 8 choghadiyas of 1 h 41 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 4 at 250°. It leaves at 13:49, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 194.1° + 250.2° = 444.3°, one full turn and 84.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 00:27 Thu, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava ended at 02:44, when the lead reached 54°; Balava runs until 16:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:28 to 07:29 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 24 Nov, finds it in Vrishchika and begins Margashirsha.

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 26 Oct, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1973, 15:45 Tue. Since then the Sun has moved 204° round the stars. Vikram Samvat numbers that year 2030; Shaka Samvat numbers it 1895.
