Panchang in Deva, Hunedoara County, Romania Mon 11 Jun 2018

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 07:34 on Mon 11 Jun to 05:04 on Tue 12 Jun, so only Monday’s pradosha (21:18–22:58) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Deva

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, 05:37 here. Ekadashi ended at 09:24 Sun, before it. Dwadashi ends at 07:34, when the lead reaches 324°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 07:34 and ended at 05:04 Tue, between the sunrises of 05:37 and 05:37 Tue. Monday reads Dwadashi and Tuesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Sun 10 Jun ran from sunset 21:17 Sun to sunrise 05:37, 8 h 20 m. Cut into 15 muhurtas of 33 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 21:18, splits into 8 choghadiyas of 1 h 57 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:18 to 05:37 Tue, splits into 8 choghadiyas of 1 h 2 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 2 at 16°40′. It leaves at 18:35, for Krittika.

Add the Sun's and the Moon's places among the stars: 56° + 19° = 75°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 13:31, 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 ended at 20:34 Sun, when the lead reached 318°; Taitila runs until 07:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 14:47 Tue to 13 Jun 22:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 09:06 Fri, 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 13 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 2018, 15:11 Sat. Since then the Sun has moved 83.2° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
