Panchang in Sevan, Gegharkunik, Armenia Sun 6 Apr 2081

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:18 on Sun 6 Apr to 08:40 on Mon 7 Apr, so only Sunday’s pradosha (19:30–21:42) 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, 06:34 here. Dwadashi ended at 06:18, before it. Trayodashi ends at 08:40 Mon, when the lead reaches 336°. The lead passed 180° at the full moon of 25 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:18, before sunrise at 06:34, and ends at 08:40 Mon, after the next sunrise at 06:33 Mon. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Sat 5 Apr ran from sunset 19:29 Sat to sunrise 06:34, 11 h 5 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 19:30, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:30 to 06:33 Mon, splits into 8 choghadiyas of 1 h 22 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 3 at 313°20′. It leaves at 14:26, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 352° + 316.1° = 668.1°, one full turn and 308.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 04:45 Mon, then Brahma.

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 19:31, when the lead reaches 330°; Vanija until 08:40 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:33 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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 9 Apr, finds it in Meena and begins Chaitra.

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 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2080, 16:07 Thu. Since then the Sun has moved 375.2° round the stars. Vikram Samvat numbers that year 2137; Shaka Samvat numbers it 2002.
