Panchang in Sevan, Gegharkunik, Armenia Fri 16 Nov 2040

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:05 on Fri 16 Nov to 23:19 on Fri 16 Nov, so only Friday’s pradosha (17:41–20:30) 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, 07:47 here. Dwadashi ended at 00:05, before it. Trayodashi ends at 23:19, when the lead reaches 156°. The lead passed 0° at the new moon of 4 Nov, so the Moon is waxing: Shukla paksha.

The night of Thu 15 Nov ran from sunset 17:42 Thu to sunrise 07:47, 14 h 5 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:47 to 17:41, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:41 to 07:49 Sat, splits into 8 choghadiyas of 1 h 46 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 11:24, for Ashwini.

Add the Sun's and the Moon's places among the stars: 210° + 358° = 568°, one full turn and 208°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 16:45, then Vyatipata.

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 11:39, when the lead reaches 150°; Taitila until 23:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:47 to 07:49 Sat, so the hours after midnight still belong to Shukrawara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 4 Dec, finds it in Vrishchika and begins Margashirsha.

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 4 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2040, 18:00 Wed. Since then the Sun has moved 212.1° round the stars. Vikram Samvat numbers that year 2097; Shaka Samvat numbers it 1962.
