Panchang in Progress, Amur Oblast, Russia Thu 23 Jun 2016

The Sankashti fast is broken at moonrise. Chaturthi runs from 20:35 on Thu 23 Jun to 20:01 on Fri 24 Jun, so it holds moonrise only on Thu 23 Jun, at 22:11. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Progress

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, 04:13 here. Dwitiya ended at 20:47 Wed, before it. Tritiya ends at 20:35, when the lead reaches 216°. The lead passed 180° at the full moon of 20 Jun, so the Moon is waning: Krishna paksha.

The night of Wed 22 Jun ran from sunset 20:32 Wed to sunrise 04:13, 7 h 41 m. Cut into 15 muhurtas of 30 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:13 to 20:32, splits into 8 choghadiyas of 2 h 2 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:32 to 04:14 Fri, splits into 8 choghadiyas of 57 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 12:38, for Shravana.

Add the Sun's and the Moon's places among the stars: 67.7° + 275.4° = 343.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 10:19, then Vaidhriti.

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 runs until 08:44, when the lead reaches 210°; Vishti until 20:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:13 to 04:14 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 4 Jul, finds it in Mithuna and begins Ashadha.

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 4 Jul, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 20:23 Thu. Since then the Sun has moved 73.7° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
