Panchang in Mapleton, Utah, United States Sun 10 Jun 2018

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 22:34 on Sun 10 Jun to 20:04 on Mon 11 Jun, so it touches only Sunday’s pradosha (20:55–22:43). No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Mapleton

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, 05:56 here. Ekadashi ended at 00:24, before it. Dwadashi ends at 22:34, when the lead reaches 324°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Sat 9 Jun ran from sunset 20:54 Sat to sunrise 05:56, 9 h 2 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:56 to 20:55, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:55 to 05:56 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 10:59, for Bharani.

Add the Sun's and the Moon's places among the stars: 55.5° + 10.4° = 65.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 07:14, then Atiganda.

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 11:34, when the lead reaches 318°; Taitila until 22:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:56 to 05:56 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 05:47 Tue to 13 Jun 13:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 00:06 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, 07:11 Sat. Since then the Sun has moved 82.7° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
