Panchang in Deva, Hunedoara County, Romania Wed 4 Jan 2023

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:32 on Tue 3 Jan to 20:31 on Wed 4 Jan, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Wed 4 Jan. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Deva

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 08:09 here. Dwadashi ended at 18:32 Tue, before it. Trayodashi ends at 20:31, when the lead reaches 156°. The lead passed 0° at the new moon of 23 Dec, so the Moon is waxing: Shukla paksha.

The night of Tue 3 Jan ran from sunset 16:55 Tue to sunrise 08:09, 15 h 14 m. Cut into 15 muhurtas of 1 h 0 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:09 to 16:56, splits into 8 choghadiyas of 1 h 5 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:56 to 08:09 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 3 at 46°40′. It leaves at 15:18, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 259.4° + 49.7° = 309.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 04:03 Thu, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava ended at 07:29, when the lead reached 150°; Taitila runs until 20:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:09 to 08:09 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 21 Jan, finds it in Makara and begins Magha.

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 23 Dec, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 2022, 09:24 Fri. Since then the Sun has moved 272.1° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
