Panchang in Khmelnytskyi, Ukraine Thu 7 Jan 2016

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:24 on Thu 7 Jan to 04:43 on Fri 8 Jan, so only Thursday’s pradosha (16:29–19:36) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Khmelnytskyi

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, 08:06 here. Dwadashi ended at 04:24, before it. Trayodashi ends at 04:43 Fri, when the lead reaches 336°. The lead passed 180° at the full moon of 25 Dec, so the Moon is waning: Krishna paksha.

The night of Wed 6 Jan ran from sunset 16:28 Wed to sunrise 08:06, 15 h 38 m. Cut into 15 muhurtas of 1 h 2 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:06 to 16:29, splits into 8 choghadiyas of 1 h 2 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:29 to 08:06 Fri, splits into 8 choghadiyas of 1 h 57 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 1 at 226°40′. It leaves at 06:17 Fri, for Mula.

Add the Sun's and the Moon's places among the stars: 262.3° + 228.1° = 490.4°, one full turn and 130.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 13:16, then Vriddhi.

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 16:39, when the lead reaches 330°; Vanija until 04:43 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:06 to 08:06 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 10 Jan, finds it in Dhanu and begins Pausha.

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 10 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 11:36 Fri. Since then the Sun has moved 286.9° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
