Panchang in Midleton, Munster, Ireland Wed 25 May 2016

The Sankashti fast is broken at moonrise. Chaturthi runs from 02:15 on Wed 25 May to 02:50 on Thu 26 May, so it holds moonrise only on Wed 25 May, at 00:24 Thu. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Midleton

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 02:15, before it. Chaturthi ends at 02:50 Thu, when the lead reaches 228°. The lead passed 180° at the full moon of 21 May, so the Moon is waning: Krishna paksha.

The night of Tue 24 May ran from sunset 21:33 Tue to sunrise 05:25, 7 h 52 m. Cut into 15 muhurtas of 31 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 21:34, splits into 8 choghadiyas of 2 h 1 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:34 to 05:24 Thu, splits into 8 choghadiyas of 58 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 2 at 256°40′. It leaves at 22:07, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 40.3° + 257.8° = 298.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 20:24, then Shukla.

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 14:35, when the lead reaches 222°; Balava until 02:50 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:24 Thu, so the hours after midnight still belong to Budhawara.

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, 5 Jun, 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 5 Jun, 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: 7 Apr 2016, 12:23 Thu. Since then the Sun has moved 46.3° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
