Panchang in Sevan, Gegharkunik, Armenia Fri 13 Aug 2004

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:28 on Fri 13 Aug to 03:30 on Sat 14 Aug, so only Friday’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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 07:08 here. Dwadashi ended at 01:28, before it. Trayodashi ends at 03:30 Sat, when the lead reaches 336°. The lead passed 180° at the full moon of 31 Jul, so the Moon is waning: Krishna paksha.

The night of Thu 12 Aug ran from sunset 21:01 Thu to sunrise 07:08, 10 h 7 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 Sat, 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 2 at 83°20′. It leaves at 03:03 Sat, for Pushya.

Add the Sun's and the Moon's places among the stars: 116.8° + 83.4° = 200.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 07:33 Sat, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 14:32, when the lead reaches 330°; Vanija until 03:30 Sat.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 16:23 Sat to 16 Aug 06:23 Mon the Sun stayed in Karka, entering Simha at 16 Aug 16:18 Mon, 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 2004, 02:41 Sun. Since then the Sun has moved 140.1° round the stars. Vikram Samvat numbers that year 2061; Shaka Samvat numbers it 1926.
