Panchang in Myshkin, Yaroslavl Oblast, Russia Wed 27 Jan 2016

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:25 on Wed 27 Jan to 09:27 on Thu 28 Jan, so it holds moonrise only on Wed 27 Jan, at 20:56. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Myshkin

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, 08:40 here. Tritiya ended at 07:25, before it. Chaturthi ends at 09:27 Thu, when the lead reaches 228°. The lead passed 180° at the full moon of 24 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 07:25, before sunrise at 08:40, and ends at 09:27 Thu, after the next sunrise at 08:38 Thu. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Tue 26 Jan ran from sunset 16:35 Tue to sunrise 08:40, 16 h 5 m. Cut into 15 muhurtas of 1 h 4 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:40 to 16:37, splits into 8 choghadiyas of 59 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:37 to 08:38 Thu, splits into 8 choghadiyas of 2 h 0 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 2 at 136°40′. It leaves at 23:27, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 282.6° + 139.2° = 421.8°, one full turn and 61.8°. 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 17:30, then Atiganda.

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 20:22, when the lead reaches 222°; Balava until 09:27 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:40 to 08:38 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 8 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 8 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: 20 Mar 2015, 12:36 Fri. Since then the Sun has moved 307.2° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
