Panchang in Midleton, Munster, Ireland Sun 1 Jul 2018

The Sankashti fast is broken at moonrise. Chaturthi runs from 13:24 on Sun 1 Jul to 15:50 on Mon 2 Jul, so it holds moonrise only on Sun 1 Jul, at 23:53. 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: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 05:17 here. Dwitiya ended at 10:50 Sat, before it. Tritiya ends at 13:24, when the lead reaches 216°. The lead passed 180° at the full moon of 28 Jun, so the Moon is waning: Krishna paksha.

The night of Sat 30 Jun ran from sunset 21:55 Sat to sunrise 05:17, 7 h 22 m. Cut into 15 muhurtas of 29 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:17 to 21:55, splits into 8 choghadiyas of 2 h 4 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:55 to 05:18 Mon, splits into 8 choghadiyas of 55 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 3 at 286°40′. It leaves at 17:06, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 75.2° + 287.5° = 362.7°, one full turn and 2.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 01:15 Mon, then Priti.

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 00:08, when the lead reached 210°; Vishti runs until 13:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:17 to 05:18 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 13 Jul, 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 13 Jul, 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: 17 Mar 2018, 13:11 Sat. Since then the Sun has moved 102.4° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
