Panchang in Myshkin, Yaroslavl Oblast, Russia Wed 25 Oct 2017

The evening arghya is offered at sunset. Shashthi runs from 07:08 on Wed 25 Oct to 09:45 on Thu 26 Oct, so it holds sunset only on Wed 25 Oct, at 16:55. No text giving Chhath · Sandhya Arghya’s time was found; sunset is Tithika’s convention.

Chhath: every date in Myshkin

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 07:23 here. Panchami ended at 07:08, before it. Shashthi ends at 09:45 Thu, when the lead reaches 72°. The lead passed 0° at the new moon of 19 Oct, so the Moon is waxing: Shukla paksha.

The night of Tue 24 Oct ran from sunset 16:58 Tue to sunrise 07:23, 14 h 25 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:23 to 16:55, 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 night here, 16:55 to 07:25 Thu, 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 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 3 at 246°40′. It leaves at 18:18, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 187.8° + 248° = 435.8°, one full turn and 75.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 15:14, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava runs until 20:27, when the lead reaches 66°; Taitila until 09:45 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:23 to 07:25 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, 18 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 19 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: 28 Mar 2017, 05:57 Tue. Since then the Sun has moved 204.3° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
