Panchang in Mapleton, Utah, United States Sat 30 Sep 2028

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:04 on Sat 30 Sep to 05:35 on Sun 1 Oct, so only Saturday’s pradosha (19:09–21:36) falls within it. 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: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 07:22 here. Dwadashi ended at 03:04, before it. Trayodashi ends at 05:35 Sun, when the lead reaches 156°. The lead passed 0° at the new moon of 18 Sep, so the Moon is waxing: Shukla paksha.

The night of Fri 29 Sep ran from sunset 19:10 Fri to sunrise 07:22, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:22 to 19:09, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:09 to 07:23 Sun, splits into 8 choghadiyas of 1 h 31 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 1 at 306°40′. It leaves at 04:27 Sun, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 163.6° + 309.6° = 473.2°, one full turn and 113.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 20:01, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava runs until 16:19, when the lead reaches 150°; Taitila until 05:35 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:22 to 07:23 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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 17 Oct, finds it in Tula and begins Kartika.

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 18 Sep, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 2028, 22:31 Sat. Since then the Sun has moved 181.8° round the stars. Vikram Samvat numbers that year 2085; Shaka Samvat numbers it 1950.
