Panchang in Quva, Fergana, Uzbekistan Sun 14 May 2017

The Sankashti fast is broken at moonrise. Chaturthi runs from 09:47 on Sun 14 May to 12:08 on Mon 15 May, so it holds moonrise only on Sun 14 May, at 22:15. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Quva

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, 04:56 here. Dwitiya ended at 07:21 Sat, before it. Tritiya ends at 09:47, when the lead reaches 216°. The lead passed 180° at the full moon of 11 May, so the Moon is waning: Krishna paksha.

The night of Sat 13 May ran from sunset 19:19 Sat to sunrise 04:56, 9 h 37 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:56 to 19:20, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:20 to 04:55 Mon, splits into 8 choghadiyas of 1 h 11 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 01:38 Mon, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 29.3° + 243.1° = 272.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 19:10, then Sadhya.

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 20:34 Sat, when the lead reached 210°; Vishti runs until 09:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:56 to 04:55 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 26 May, finds it in Vrishabha and begins Jyeshtha.

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 26 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 07:57 Tue. Since then the Sun has moved 45.8° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
