Panchang in Sevan, Gegharkunik, Armenia Thu 12 Nov 2020

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:00 on Thu 12 Nov to 16:29 on Fri 13 Nov, so it touches only Thursday’s pradosha (17:44–20:32). No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Dhanteras puja muhurat: pradosha, 17:44–20:32. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 17:50 to 19:39.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:00 on Thu 12 Nov to 16:29 on Fri 13 Nov, so it touches only Thursday’s pradosha (17:44–20:32). 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, 07:43 here. Ekadashi ended at 23:11 Wed, before it. Dwadashi ends at 20:00, when the lead reaches 324°. The lead passed 180° at the full moon of 31 Oct, so the Moon is waning: Krishna paksha.

The night of Wed 11 Nov ran from sunset 17:45 Wed to sunrise 07:43, 13 h 58 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:43 to 17:44, splits into 8 choghadiyas of 1 h 15 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:44 to 07:44 Fri, splits into 8 choghadiyas of 1 h 45 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 00:24 Fri, for Chitra.

Add the Sun's and the Moon's places among the stars: 206.1° + 163° = 369.1°, one full turn and 9.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 14:14, then Priti.

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 runs until 09:39, when the lead reaches 318°; Taitila until 20:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:43 to 07:44 Fri, so the hours after midnight still belong to Guruwara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 15 Nov, finds it in Tula and begins Kartika.

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 15 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2020, 13:28 Tue. Since then the Sun has moved 226° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
