Panchang in Sevan, Gegharkunik, Armenia Sat 13 Sep 2031

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi began at 18:45 on Sat 13 Sep, before that evening’s pradosha, and ended at 20:32 on Sun 14 Sep, partway into the next. The Nirnayasindhu takes the evening Trayodashi fills: Sat 13 Sep. 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, 06:38 here. Ekadashi ended at 16:36 Fri, before it. Dwadashi ends at 18:45, when the lead reaches 324°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

The night of Fri 12 Sep ran from sunset 19:14 Fri to sunrise 06:38, 11 h 24 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:38 to 19:13, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:13 to 06:39 Sun, splits into 8 choghadiyas of 1 h 25 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 4 at 103°20′. It leaves at 11:28, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 145.8° + 104.2° = 250°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 12:39, then Shiva.

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 05:43, when the lead reached 318°; Taitila runs until 18:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:38 to 06:39 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 18 Aug 08:32 Mon to 16 Sep 22:46 Tue the Sun stayed in Simha, entering Kanya at 17 Sep 13:19 Wed, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 16 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 07:49 Sun. Since then the Sun has moved 167.8° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
