Panchang in Myjava, Trenčín Region, Slovakia Tue 15 Aug 1978

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 21:59 on Tue 15 Aug to 18:25 on Wed 16 Aug, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Tue 15 Aug. 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: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 04:41 here. Ekadashi ended at 01:18, before it. Dwadashi ends at 21:59, when the lead reaches 144°. The lead passed 0° at the new moon of 4 Aug, so the Moon is waxing: Shukla paksha.

The night of Mon 14 Aug ran from sunset 19:07 Mon to sunrise 04:41, 9 h 34 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:41 to 19:05, 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, 19:05 to 04:42 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 4 at 250°. It leaves at 06:15, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 118.4° + 252.4° = 370.8°, one full turn and 10.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 08:34, then Priti.

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 11:40, when the lead reaches 138°; Balava until 21:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:41 to 04:42 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, 2 Sep, 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 4 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1978, 16:15 Fri. Since then the Sun has moved 124.5° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
