Panchang in Sevan, Gegharkunik, Armenia Wed 12 Jul 1950

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:20 on Wed 12 Jul to 06:03 on Thu 13 Jul, so only Wednesday’s pradosha (19:31–21:20) 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, 04:39 here. Dwadashi ended at 04:20, before it. Trayodashi ends at 06:03 Thu, when the lead reaches 336°. The lead passed 180° at the full moon of 29 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 04:20, before sunrise at 04:39, and ends at 06:03 Thu, after the next sunrise at 04:39 Thu. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Tue 11 Jul ran from sunset 19:31 Tue to sunrise 04:39, 9 h 8 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:39 to 19:31, splits into 8 choghadiyas of 1 h 51 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 11:01, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 86° + 50.1° = 136.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 00:00 Thu, then Dhruva.

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 17:15, when the lead reaches 330°; Vanija until 06:03 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:39 to 04:39 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Jun 18:52 Thu to 15 Jul 08:05 Sat the Sun stayed in Mithuna, entering Karka at 16 Jul 09:41 Sun, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 Jul, with the Sun in Mithuna, begins Ashadha (Adhik). Until then this Krishna paksha reads Ashadha (Adhik) here, and Ashadha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 18:20 Sat. Since then the Sun has moved 111.7° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
