Panchang in Sevan, Gegharkunik, Armenia Mon 28 Dec 2043

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:25 on Mon 28 Dec to 09:01 on Tue 29 Dec, so only Monday’s pradosha (17:40–20:36) 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 08:22 here. Dwadashi ended at 06:25, before it. Trayodashi ends at 09:01 Tue, when the lead reaches 336°. The lead passed 180° at the full moon of 16 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:25, before sunrise at 08:22, and ends at 09:01 Tue, after the next sunrise at 08:22 Tue. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Sun 27 Dec ran from sunset 17:39 Sun to sunrise 08:22, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:22 to 17:40, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:40 to 08:22 Tue, splits into 8 choghadiyas of 1 h 50 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 2 at 216°40′. It leaves at 04:33 Tue, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 251.8° + 216.7° = 468.5°, one full turn and 108.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 05:46 Tue, then Ganda.

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 19:43, when the lead reaches 330°; Vanija until 09:01 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:22 to 08:22 Tue, so the hours after midnight still belong to Somawara.

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, 31 Dec, 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 31 Dec, 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: 9 Apr 2043, 23:06 Thu. Since then the Sun has moved 256.4° round the stars. Vikram Samvat numbers that year 2100; Shaka Samvat numbers it 1965.
