Panchang in Sevan, Gegharkunik, Armenia Sat 11 Jun 1904

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:22 on Sat 11 Jun to 02:56 on Sun 12 Jun, so only Saturday’s pradosha (19:27–21:15) 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, 04:28 here. Dwadashi ended at 03:24, before it. Trayodashi ends at 02:58 Sun, when the lead reaches 336°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Fri 10 Jun ran from sunset 19:29 Fri to sunrise 04:28, 8 h 59 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:28 to 19:29, 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, 19:29 to 04:28 Sun, 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 3 at 20°. It leaves at 13:36, for Krittika.

Add the Sun's and the Moon's places among the stars: 57.2° + 21.7° = 78.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 06:27, then Sukarma.

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 15:17, when the lead reaches 330°; Vanija until 02:58 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:28 to 04:28 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 13:57 Sun to 14 Jun 00:10 Tue the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 03:50 Tue, 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 14 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: 17 Mar 1904, 08:39 Thu. Since then the Sun has moved 83.5° round the stars. Vikram Samvat numbers that year 1961; Shaka Samvat numbers it 1826.
