Panchang in Myjava, Trenčín Region, Slovakia Tue 14 Aug 2012

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:05 on Tue 14 Aug to 18:39 on Wed 15 Aug, so only Tuesday’s pradosha (20:06–22:01) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Myjava

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, 05:41 here. Ekadashi ended at 16:51 Mon, before it. Dwadashi ends at 18:05, when the lead reaches 324°. The lead passed 180° at the full moon of 2 Aug, so the Moon is waning: Krishna paksha.

The night of Mon 13 Aug ran from sunset 20:07 Mon to sunrise 05:41, 9 h 34 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 20:06, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:06 to 05:42 Wed, splits into 8 choghadiyas of 1 h 12 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 3 at 73°20′. It leaves at 13:49, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 117.7° + 75.8° = 193.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 17:18, then Siddhi.

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 05:33, when the lead reached 318°; Taitila runs until 18:05.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:42 Wed, so the hours after midnight still belong to Mangalawara.

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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 17 Aug, finds it in Simha and begins Bhadrapada.

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 17 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 15:37 Thu. Since then the Sun has moved 139.4° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
