Panchang in Davinópolis, Maranhão, Brazil Wed 13 Dec 2000

The Sankashti fast is broken at moonrise. Chaturthi runs from 20:20 on Wed 13 Dec to 17:18 on Thu 14 Dec, so it holds moonrise only on Wed 13 Dec, at 20:51. 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: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 05:50 here. Dwitiya ended at 23:34 Tue, before it. Tritiya ends at 20:20, when the lead reaches 216°. The lead passed 180° at the full moon of 11 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 07:05, came before Dwitiya ended at 08:04: this day reads Dwitiya. Tritiya ends at 04:50 Thu, before the next sunrise, so no day here reads Tritiya: it is kshaya.

Sunrise here, 05:50, came after Dwitiya ended at 23:34 Tue: this day reads Tritiya.

The night of Tue 12 Dec ran from sunset 18:16 Tue to sunrise 05:50, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:50 to 18:17, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 05:51 Thu, splits into 8 choghadiyas of 1 h 26 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 2 at 83°20′. It leaves at 18:36, for Pushya.

Add the Sun's and the Moon's places among the stars: 237.8° + 85.4° = 323.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 21:08, then Indra.

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 09:56, when the lead reaches 210°; Vishti until 20:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:50 to 05:51 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 25 Dec, finds it in Dhanu and begins Pausha.

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 25 Dec, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 2000, 15:12 Tue. Since then the Sun has moved 246.4° round the stars. Vikram Samvat numbers that year 2057; Shaka Samvat numbers it 1922.
