Panchang in Sevan, Gegharkunik, Armenia Mon 12 Aug 2080

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:21 on Mon 12 Aug to 19:46 on Tue 13 Aug, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Mon 12 Aug. 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, 06:08 here. Ekadashi ended at 02:35, before it. Dwadashi ends at 23:21, when the lead reaches 324°. The lead passed 180° at the full moon of 31 Jul, so the Moon is waning: Krishna paksha.

The night of Sun 11 Aug ran from sunset 20:02 Sun to sunrise 06:08, 10 h 6 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 20:00, 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 night here, 20:00 to 06:09 Tue, splits into 8 choghadiyas of 1 h 16 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 1 at 66°40′. It leaves at 23:19, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 115.3° + 69.4° = 184.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 09:08, then Vajra.

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 13:01, when the lead reaches 318°; Taitila until 23:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:09 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 05:22 Wed to 15 Aug 12:14 Thu the Sun stayed in Karka, entering Simha at 17 Aug 02:43 Sat, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana itself.

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 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) 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 138.5° round the stars. Vikram Samvat numbers that year 2137; Shaka Samvat numbers it 2002.
