Panchang in Olean, New York, United States Sun 12 Jun 2011

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 22:50 on Sun 12 Jun to 20:21 on Mon 13 Jun, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Sun 12 Jun. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Olean

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, 05:37 here. Ekadashi ended at 01:26, before it. Dwadashi ends at 22:50, when the lead reaches 144°. The lead passed 0° at the new moon of 1 Jun, so the Moon is waxing: Shukla paksha.

The night of Sat 11 Jun ran from sunset 20:49 Sat to sunrise 05:37, 8 h 48 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 20:49, splits into 8 choghadiyas of 1 h 54 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:49 to 05:37 Mon, splits into 8 choghadiyas of 1 h 6 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 2 at 190°. It leaves at 19:53, for Vishakha.

Add the Sun's and the Moon's places among the stars: 57.1° + 191.4° = 248.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 13:08, then Shiva.

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 runs until 12:07, when the lead reaches 138°; Balava until 22:50.

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

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 1 Jul, finds it in Mithuna and begins Ashadha.

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 1 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 2011, 10:32 Sun. Since then the Sun has moved 67.6° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
