Panchang in Sevan, Gegharkunik, Armenia Sat 26 Jan 2086

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi began at 17:37 on Sat 26 Jan, before that evening’s pradosha, and ended at 18:40 on Sun 27 Jan, partway into the next. The Nirnayasindhu takes the evening Trayodashi fills: Sat 26 Jan. 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, 08:14 here. Ekadashi ended at 16:59 Fri, before it. Dwadashi ends at 17:37, when the lead reaches 144°. The lead passed 0° at the new moon of 15 Jan, so the Moon is waxing: Shukla paksha.

The night of Fri 25 Jan ran from sunset 18:09 Fri to sunrise 08:14, 14 h 5 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:14 to 18:10, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:10 to 08:13 Sun, splits into 8 choghadiyas of 1 h 45 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 18:55, for Ardra.

Add the Sun's and the Moon's places among the stars: 281.6° + 61° = 342.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 15:19, then Vaidhriti.

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 05:15, when the lead reached 138°; Balava runs until 17:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:14 to 08:13 Sun, so the hours after midnight still belong to Shaniwara.

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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 14 Feb, finds it in Kumbha and begins Phalguna.

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 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 2085, 20:38 Sun. Since then the Sun has moved 300.9° round the stars. Vikram Samvat numbers that year 2142; Shaka Samvat numbers it 2007.
