Panchang in Ipameri, Goiás, Brazil Sun 31 Jan 2021

The Sankashti fast is broken at moonrise. Chaturthi runs from 11:55 on Sun 31 Jan to 09:55 on Mon 1 Feb, so it holds moonrise only on Sun 31 Jan, at 21:21. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Ipameri

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, 05:59 here. Dwitiya ended at 13:43 Sat, before it. Tritiya ends at 11:55, when the lead reaches 216°. The lead passed 180° at the full moon of 28 Jan, so the Moon is waning: Krishna paksha.

The night of Sat 30 Jan ran from sunset 18:52 Sat to sunrise 05:59, 11 h 7 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:59 to 18:52, 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 night here, 18:52 to 06:00 Mon, 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 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 3 at 140°. It leaves at 16:47, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 287.6° + 140.3° = 427.9°, one full turn and 67.9°. 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 01:14 Mon, then Sukarma.

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 00:50, when the lead reached 210°; Vishti runs until 11:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:59 to 06:00 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 13 Jan, inside the month. The next new moon, 11 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 11 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: 24 Mar 2020, 06:28 Tue. Since then the Sun has moved 307.5° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
