Panchang in Sevan, Gegharkunik, Armenia Tue 13 Aug 1985

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:08 on Tue 13 Aug to 17:45 on Wed 14 Aug, so only Tuesday’s pradosha (21:00–23:02) 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, 07:08 here. Ekadashi ended at 17:47 Mon, before it. Dwadashi ends at 18:08, when the lead reaches 324°. The lead passed 180° at the full moon of 1 Aug, so the Moon is waning: Krishna paksha.

The night of Mon 12 Aug ran from sunset 21:02 Mon to sunrise 07:08, 10 h 6 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:08 to 21:00, 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, 21:00 to 07:09 Wed, 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 3 at 73°20′. It leaves at 16:10, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 116.6° + 75.2° = 191.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 21:21, then Siddhi.

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 06:03, when the lead reached 318°; Taitila runs until 18:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:08 to 07:09 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 04:56 Thu to 16 Aug 15:05 Fri the Sun stayed in Karka, entering Simha at 16 Aug 19:23 Fri, 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 16 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 1985, 15:58 Thu. Since then the Sun has moved 139.4° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
