Panchang in Myshkin, Yaroslavl Oblast, Russia Thu 6 Jul 2023

The Sankashti fast is broken at moonrise. Chaturthi runs from 04:00 on Thu 6 Jul to 00:43 on Fri 7 Jul, so it holds moonrise only on Thu 6 Jul, at 23:30. 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: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 03:34 here. Dwitiya ended at 07:32 Wed, before it. Tritiya ends at 04:00, when the lead reaches 216°. The lead passed 180° at the full moon of 3 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 04:00 and ended at 00:43 Fri, between the sunrises of 03:34 and 03:35 Fri. Thursday reads Tritiya and Friday reads Panchami: Chaturthi is a kshaya tithi here.

The night of Wed 5 Jul ran from sunset 21:26 Wed to sunrise 03:34, 6 h 8 m. Cut into 15 muhurtas of 24 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 03:34 to 21:26, splits into 8 choghadiyas of 2 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:26 to 03:35 Fri, splits into 8 choghadiyas of 46 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 1 at 293°20′. It leaves at 21:55, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 79.5° + 295.3° = 374.8°, one full turn and 14.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 21:29, then Ayushmana.

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 17:45 Wed, when the lead reached 210°; Vishti runs until 04:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 03:34 to 03:35 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: Mithuna gives Ashadha. The Sun enters Karka on 17 Jul, inside the month. The next new moon, 17 Jul, finds it in Karka and begins Shravana.

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 17 Jul, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2023, 20:23 Tue. Since then the Sun has moved 102.9° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
