Panchang in Ipameri, Goiás, Brazil Thu 12 Jan 2012

The Sankashti fast is broken at moonrise. Chaturthi runs from 03:10 on Thu 12 Jan to 01:40 on Fri 13 Jan, so it holds moonrise only on Thu 12 Jan, at 22:22. 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: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 06:47 here. Tritiya ended at 03:10, before it. Chaturthi ends at 01:40 Fri, when the lead reaches 228°. The lead passed 180° at the full moon of 9 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Wed 11 Jan ran from sunset 19:53 Wed to sunrise 06:47, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:47 to 19:53, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:53 to 06:48 Fri, splits into 8 choghadiyas of 1 h 21 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 2 at 123°20′. It leaves at 20:31, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 267.5° + 125.4° = 392.9°, one full turn and 32.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 18:13, then Saubhagya.

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 14:27, when the lead reaches 222°; Balava until 01:40 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:47 to 06:48 Fri, so the hours after midnight still belong to Guruwara.

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, 23 Jan, 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 23 Jan, 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: 3 Apr 2011, 11:32 Sun. Since then the Sun has moved 278° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
