Panchang in Sevan, Gegharkunik, Armenia Thu 29 Jul 2004

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 09:36 on Thu 29 Jul to 06:07 on Fri 30 Jul, so only Thursday’s pradosha (21:17–23:13) 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: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 06:54 here. Ekadashi ended at 12:50 Wed, before it. Dwadashi ends at 09:36, when the lead reaches 144°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 09:36 and ended at 06:07 Fri, between the sunrises of 06:54 and 06:55 Fri. Thursday reads Dwadashi and Friday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Wed 28 Jul ran from sunset 21:18 Wed to sunrise 06:54, 9 h 36 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:54 to 21:17, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:17 to 06:55 Fri, splits into 8 choghadiyas of 1 h 12 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 2 at 243°20′. It leaves at 20:35, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 102.4° + 244.8° = 347.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 02:13 Fri, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava ended at 23:15 Wed, when the lead reached 138°; Balava runs until 09:36.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:54 to 06:55 Fri, so the hours after midnight still belong to Guruwara.

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 17 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

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 125.7° round the stars. Vikram Samvat numbers that year 2061; Shaka Samvat numbers it 1926.
