Panchang in Sevan, Gegharkunik, Armenia Sun 6 Jan 2092

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 13:56 on Sun 6 Jan to 11:00 on Mon 7 Jan, so only Sunday’s pradosha (17:48–20:43) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

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, 08:23 here. Ekadashi ended at 16:51 Sat, before it. Dwadashi ends at 13:56, when the lead reaches 324°. The lead passed 180° at the full moon of 26 Dec, so the Moon is waning: Krishna paksha.

The night of Sat 5 Jan ran from sunset 17:47 Sat to sunrise 08:23, 14 h 36 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:23 to 17:48, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:48 to 08:23 Mon, splits into 8 choghadiyas of 1 h 49 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 16:48, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 260.7° + 221.5° = 482.2°, one full turn and 122.2°. 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 01:23 Mon, then Vriddhi.

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 03:25, when the lead reached 318°; Taitila runs until 13:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:23 to 08:23 Mon, so the hours after midnight still belong to Raviwara.

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 17 Dec, inside the month. The next new moon, 9 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 9 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 2091, 07:47 Tue. Since then the Sun has moved 286° round the stars. Vikram Samvat numbers that year 2148; Shaka Samvat numbers it 2013.
