Panchang in Midleton, Munster, Ireland Wed 15 Nov 2017

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 07:40 on Wed 15 Nov to 08:39 on Thu 16 Nov, so only Wednesday’s pradosha (16:41–19:44) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Midleton

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 07:52 here. Dwadashi ended at 07:40, before it. Trayodashi ends at 08:39 Thu, when the lead reaches 336°. The lead passed 180° at the full moon of 4 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 07:40, before sunrise at 07:52, and ends at 08:39 Thu, after the next sunrise at 07:54 Thu. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Tue 14 Nov ran from sunset 16:43 Tue to sunrise 07:52, 15 h 9 m. Cut into 15 muhurtas of 1 h 0 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:52 to 16:41, splits into 8 choghadiyas of 1 h 6 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:41 to 07:54 Thu, splits into 8 choghadiyas of 1 h 54 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 4 at 170°. It leaves at 08:15, for Chitra.

Add the Sun's and the Moon's places among the stars: 209° + 173.1° = 382.1°, one full turn and 22.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 15:49, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 20:07, when the lead reaches 330°; Vanija until 08:39 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:52 to 07:54 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 18 Nov, finds it in Vrishchika and begins Margashirsha.

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 18 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 03:57 Tue. Since then the Sun has moved 225.5° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
