Panchang in Myjava, Trenčín Region, Slovakia Sat 18 Nov 1972

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:05 on Sat 18 Nov to 07:43 on Sun 19 Nov, so only Saturday’s pradosha (16:06–19:05) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Myjava

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, 07:03 here. Ekadashi ended at 13:57 Fri, before it. Dwadashi ends at 11:05, when the lead reaches 144°. The lead passed 0° at the new moon of 6 Nov, so the Moon is waxing: Shukla paksha.

The night of Fri 17 Nov ran from sunset 16:07 Fri to sunrise 07:03, 14 h 56 m. Cut into 15 muhurtas of 59 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:03 to 16:06, splits into 8 choghadiyas of 1 h 7 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:06 to 07:04 Sun, splits into 8 choghadiyas of 1 h 52 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 3 at 353°20′. It leaves at 16:26, for Ashwini.

Add the Sun's and the Moon's places among the stars: 212.5° + 354.2° = 566.7°, one full turn and 206.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 17:04, then Vyatipata.

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 00:36, when the lead reached 138°; Balava runs until 11:05.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:03 to 07:04 Sun, so the hours after midnight still belong to Shaniwara.

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 15 Nov, inside the month. The next new moon, 5 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 6 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: 15 Mar 1972, 12:34 Wed. Since then the Sun has moved 241° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
