Panchang in Baoding, Hebei, China Thu 19 May 2022

The Sankashti fast is broken at moonrise. Chaturthi runs from 02:07 on Thu 19 May to 22:54 on Thu 19 May, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Thu 19 May. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Baoding

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, 05:02 here. Tritiya ended at 02:07, before it. Chaturthi ends at 22:54, when the lead reaches 228°. The lead passed 180° at the full moon of 16 May, so the Moon is waning: Krishna paksha.

The night of Wed 18 May ran from sunset 19:26 Wed to sunrise 05:02, 9 h 36 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:02 to 19:26, 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, 19:26 to 05:01 Fri, 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 4 at 250°. It leaves at 08:07, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 33.7° + 251.4° = 285.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 17:27, then Shubha.

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 12:29, when the lead reaches 222°; Balava until 22:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:02 to 05:01 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 30 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 30 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: 1 Apr 2022, 14:24 Fri. Since then the Sun has moved 46.4° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
