Panchang in Sevan, Gegharkunik, Armenia Tue 14 Dec 2032

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:23 on Tue 14 Dec to 02:12 on Wed 15 Dec, so only Tuesday’s pradosha (17:33–20:30) 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: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 08:15 here. Dwadashi ended at 03:23, before it. Trayodashi ends at 02:12 Wed, when the lead reaches 156°. The lead passed 0° at the new moon of 3 Dec, so the Moon is waxing: Shukla paksha.

The night of Mon 13 Dec ran from sunset 17:33 Mon to sunrise 08:15, 14 h 42 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:15 to 17:33, 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, 17:33 to 08:16 Wed, 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 11:13, for Krittika.

Add the Sun's and the Moon's places among the stars: 238.4° + 25° = 263.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 13:38, then Siddha.

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 runs until 14:46, when the lead reaches 150°; Taitila until 02:12 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:15 to 08:16 Wed, so the hours after midnight still belong to Mangalawara.

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 15 Dec, inside the month. The next new moon, 1 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 3 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2032, 06:39 Sat. Since then the Sun has moved 241.9° round the stars. Vikram Samvat numbers that year 2089; Shaka Samvat numbers it 1954.
