Karwa Chauth: every date in Davinópolis

The Sankashti fast is broken at moonrise. Chaturthi runs from 22:16 on Sat 19 Oct to 19:47 on Sun 20 Oct, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Sun 20 Oct. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Davinópolis

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 05:46 here. Tritiya ended at 22:16 Sat, before it. Chaturthi ends at 19:47, when the lead reaches 228°. The lead passed 180° at the full moon of 17 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:25, came before Tritiya ended at 06:46: this day reads Tritiya. Chaturthi ends at 04:17 Mon, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 05:46, came after Tritiya ended at 22:16 Sat: this day reads Chaturthi.

The night of Sat 19 Oct ran from sunset 18:01 Sat to sunrise 05:46, 11 h 45 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:46 to 18:01, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 05:46 Mon, splits into 8 choghadiyas of 1 h 28 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 2 at 43°20′. It leaves at 22:20, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 183.3° + 43.5° = 226.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 02:41 Mon, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava runs until 08:57, when the lead reaches 222°; Balava until 19:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:46 to 05:46 Mon, so the hours after midnight still belong to Raviwara.

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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 1 Nov, finds it in Tula and begins Kartika.

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 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 2024, 15:20 Mon. Since then the Sun has moved 188.1° round the stars. Vikram Samvat numbers that year 2081; Shaka Samvat numbers it 1946.
