Panchang in Sevan, Gegharkunik, Armenia Sun 17 Jun 2096

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:03 on Sun 17 Jun to 19:46 on Mon 18 Jun, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Sun 17 Jun. 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 02:09, before it. Dwadashi ends at 23:03, when the lead reaches 324°. The lead passed 180° at the full moon of 6 Jun, so the Moon is waning: Krishna paksha.

The night of Sat 16 Jun ran from sunset 20:33 Sat to sunrise 05:29, 8 h 56 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 20:33, splits into 8 choghadiyas of 1 h 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:33 to 05:29 Mon, 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 23:25, for Krittika.

Add the Sun's and the Moon's places among the stars: 61.7° + 15.6° = 77.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 09:31, 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 12:37, when the lead reaches 318°; Taitila until 23:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:29 Mon, so the hours after midnight still belong to Raviwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 20 Jun, finds it in Mithuna and begins Ashadha.

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 20 Jun, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2096, 12:56 Sat. Since then the Sun has moved 82.1° round the stars. Vikram Samvat numbers that year 2153; Shaka Samvat numbers it 2018.
