Panchang in Sevan, Gegharkunik, Armenia Wed 19 Mar 2042

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:08 on Wed 19 Mar to 04:49 on Thu 20 Mar, so only Wednesday’s pradosha (19:10–21:33) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:05 here. Ekadashi ended at 10:59 Tue, before it. Dwadashi ends at 08:08, when the lead reaches 324°. The lead passed 180° at the full moon of 7 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 08:08 and ended at 04:49 Thu, between the sunrises of 07:05 and 07:03 Thu. Wednesday reads Dwadashi and Thursday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Tue 18 Mar ran from sunset 19:09 Tue to sunrise 07:05, 11 h 56 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:05 to 19:10, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:10 to 07:03 Thu, splits into 8 choghadiyas of 1 h 29 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 2 at 296°40′. It leaves at 21:44, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 334.2° + 297.6° = 631.8°, one full turn and 271.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 19:31, then Sadhya.

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 21:38 Tue, when the lead reached 318°; Taitila runs until 08:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:05 to 07:03 Thu, so the hours after midnight still belong to Budhawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 21 Mar, finds it in Meena and begins Chaitra.

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 21 Mar, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 2041, 05:29 Mon. Since then the Sun has moved 346.9° round the stars. Vikram Samvat numbers that year 2098; Shaka Samvat numbers it 1963.
