Panchang in Sevan, Gegharkunik, Armenia Tue 10 Jun 1980

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 07:44 on Tue 10 Jun to 05:07 on Wed 11 Jun, so only Tuesday’s pradosha (20:29–22:17) 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, 05:29 here. Ekadashi ended at 10:25 Mon, before it. Dwadashi ends at 07:44, when the lead reaches 324°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 07:44 and ended at 05:07 Wed, between the sunrises of 05:29 and 05:28 Wed. Tuesday reads Dwadashi and Wednesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Mon 9 Jun ran from sunset 20:29 Mon to sunrise 05:29, 9 h 0 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 20:29, 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, 20:29 to 05:28 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 2 at 16°40′. It leaves at 19:06, for Krittika.

Add the Sun's and the Moon's places among the stars: 55.7° + 18.5° = 74.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 14:29, 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 ended at 21:04 Mon, when the lead reached 318°; Taitila runs until 07:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:28 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 14 May 16:00 Wed to 13 Jun 00:38 Fri the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 16:25 Sat, 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 13 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: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 82.9° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
