Panchang in Sevan, Gegharkunik, Armenia Sun 11 Nov 2012

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:58 on Sun 11 Nov to 09:03 on Mon 12 Nov, so only Sunday’s pradosha (17:45–20:33) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Dhanteras puja muhurat: pradosha, 17:45–20:33. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 17:54 to 19:42.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:58 on Sun 11 Nov to 09:03 on Mon 12 Nov, so only Sunday’s pradosha (17:45–20:33) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:41 here. Ekadashi ended at 14:18 Sat, before it. Dwadashi ends at 11:58, when the lead reaches 324°. The lead passed 180° at the full moon of 29 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 10 Nov ran from sunset 17:46 Sat to sunrise 07:41, 13 h 55 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:41 to 17:45, 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, 17:45 to 07:42 Mon, splits into 8 choghadiyas of 1 h 44 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 3 at 166°40′. It leaves at 18:37, for Chitra.

Add the Sun's and the Moon's places among the stars: 205.1° + 166.7° = 371.8°, one full turn and 11.8°. 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 10:01, 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 ended at 01:13, when the lead reached 318°; Taitila runs until 11:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:41 to 07:42 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 14 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 14 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: 22 Mar 2012, 18:37 Thu. Since then the Sun has moved 226.8° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
