Panchang in Codcod, Western Visayas, Philippines Tue 13 Jun 2017

The Sankashti fast is broken at moonrise. Chaturthi runs from 03:48 on Tue 13 Jun to 05:33 on Wed 14 Jun, so it holds moonrise only on Tue 13 Jun, at 21:07. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Codcod

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, 05:25 here. Tritiya ended at 03:48, before it. Chaturthi ends at 05:33 Wed, when the lead reaches 228°. The lead passed 180° at the full moon of 9 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 03:48, before sunrise at 05:25, and ends at 05:33 Wed, after the next sunrise at 05:25 Wed. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Mon 12 Jun ran from sunset 18:08 Mon to sunrise 05:25, 11 h 17 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 18:09, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:25 Wed, splits into 8 choghadiyas of 1 h 24 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 15:51, for Shravana.

Add the Sun's and the Moon's places among the stars: 58° + 274.7° = 332.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 06:33, then Indra.

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 16:43, when the lead reaches 222°; Balava until 05:33 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:25 Wed, so the hours after midnight still belong to Mangalawara.

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, 24 Jun, 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 24 Jun, 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: 28 Mar 2017, 10:57 Tue. Since then the Sun has moved 74.5° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
