Panchang in Atliaca, Guerrero, Mexico Sat 30 Dec 2023

The Sankashti fast is broken at moonrise. Chaturthi runs from 22:14 on Fri 29 Dec to 00:26 on Sun 31 Dec, so it holds moonrise only on Sat 30 Dec, at 21:37. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Atliaca

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, 07:07 here. Tritiya ended at 22:14 Fri, before it. Chaturthi ends at 00:26 Sun, when the lead reaches 228°. The lead passed 180° at the full moon of 26 Dec, so the Moon is waning: Krishna paksha.

The night of Fri 29 Dec ran from sunset 18:12 Fri to sunrise 07:07, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:07 to 18:12, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:12 to 07:07 Sun, splits into 8 choghadiyas of 1 h 36 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 3 at 113°20′. It leaves at 18:12, for Magha.

Add the Sun's and the Moon's places among the stars: 254.4° + 114.5° = 368.9°, one full turn and 8.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 15:25, then Priti.

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 11:17, when the lead reaches 222°; Balava until 00:26 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:07 to 07:07 Sun, so the hours after midnight still belong to Shaniwara.

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 16 Dec, inside the month. The next new moon, 11 Jan, 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 11 Jan, 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: 21 Mar 2023, 11:23 Tue. Since then the Sun has moved 277.8° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
