Panchang in Myjava, Trenčín Region, Slovakia Thu 1 Dec 1983

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 15:37 on Thu 1 Dec to 14:28 on Fri 2 Dec, so only Thursday’s pradosha (15:55–19:01) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:20 here. Ekadashi ended at 17:05 Wed, before it. Dwadashi ends at 15:37, when the lead reaches 324°. The lead passed 180° at the full moon of 20 Nov, so the Moon is waning: Krishna paksha.

The night of Wed 30 Nov ran from sunset 15:56 Wed to sunrise 07:20, 15 h 24 m. Cut into 15 muhurtas of 1 h 1 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:20 to 15:55, splits into 8 choghadiyas of 1 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, 15:55 to 07:21 Fri, splits into 8 choghadiyas of 1 h 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 11:11, for Swati.

Add the Sun's and the Moon's places among the stars: 224.9° + 184.5° = 409.4°, one full turn and 49.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 13:52, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 04:18, when the lead reached 318°; Taitila runs until 15:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:20 to 07:21 Fri, so the hours after midnight still belong to Guruwara.

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, 4 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 4 Dec, 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: 13 Apr 1983, 09:58 Wed. Since then the Sun has moved 225.7° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
