Panchang in Progreso, Yucatán, Mexico Sun 28 Jan 2024

The Sankashti fast is broken at moonrise. Chaturthi runs from 18:41 on Sun 28 Jan to 21:24 on Mon 29 Jan, touching moonrise on both nights. When it does, the Dharmasindhu takes the earlier day: Sun 28 Jan. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Progreso

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, 06:37 here. Dwitiya ended at 16:07 Sat, before it. Tritiya ends at 18:41, when the lead reaches 216°. The lead passed 180° at the full moon of 25 Jan, so the Moon is waning: Krishna paksha.

The night of Sat 27 Jan ran from sunset 17:45 Sat to sunrise 06:37, 12 h 52 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:37 to 17:46, 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, 17:46 to 06:37 Mon, 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 1 at 133°20′. It leaves at 07:27 Mon, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 283.9° + 134.4° = 418.3°, one full turn and 58.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 22:13, then Atiganda.

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 ended at 05:22, when the lead reached 210°; Vishti runs until 18:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:37 to 06:37 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 9 Feb, finds it in Makara and begins Magha.

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 9 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha 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 307.3° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
