Panchang in Sevan, Gegharkunik, Armenia Tue 12 Jun 2007

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 17:16 on Tue 12 Jun to 14:08 on Wed 13 Jun, so only Tuesday’s pradosha (21:30–23:18) 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, 06:29 here. Ekadashi ended at 20:18 Mon, before it. Dwadashi ends at 17:16, when the lead reaches 324°. The lead passed 180° at the full moon of 1 Jun, so the Moon is waning: Krishna paksha.

The night of Mon 11 Jun ran from sunset 21:30 Mon to sunrise 06:29, 8 h 59 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 21:30, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:30 to 06:28 Wed, splits into 8 choghadiyas of 1 h 7 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 02:09 Wed, for Krittika.

Add the Sun's and the Moon's places among the stars: 56.8° + 14.6° = 71.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 19:41, then Sukarma.

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 06:48, when the lead reaches 318°; Taitila until 17:16.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:28 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 17 May 00:27 Thu to 15 Jun 08:13 Fri the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 15:22 Fri, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 82.6° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
