Panchang in Simrishamn, Skåne, Sweden Fri 24 Nov 2023

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 14:37 on Fri 24 Nov to 12:52 on Sat 25 Nov, so only Friday’s pradosha (15:43–18:57) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Simrishamn

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 07:53 here. Ekadashi ended at 16:32 Thu, before it. Dwadashi ends at 14:37, when the lead reaches 144°. The lead passed 0° at the new moon of 13 Nov, so the Moon is waxing: Shukla paksha.

The night of Thu 23 Nov ran from sunset 15:44 Thu to sunrise 07:53, 16 h 9 m. Cut into 15 muhurtas of 1 h 4 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:53 to 15:43, 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 night here, 15:43 to 07:55 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 11:30, for Ashwini.

Add the Sun's and the Moon's places among the stars: 217.5° + 357.9° = 575.4°, one full turn and 215.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 01:53 Sat, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava ended at 03:33, when the lead reached 138°; Balava runs until 14:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:53 to 07:55 Sat, so the hours after midnight still belong to Shukrawara.

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, 13 Dec, 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 13 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2023, 18:23 Tue. Since then the Sun has moved 240.9° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
