Panchang in Myjava, Trenčín Region, Slovakia Fri 29 Jul 1966

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:24 on Fri 29 Jul to 07:16 on Sat 30 Jul, so only Friday’s pradosha (19:33–21:18) 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: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 04:18 here. Ekadashi ended at 05:56 Thu, before it. Dwadashi ends at 06:24, when the lead reaches 144°. The lead passed 0° at the new moon of 18 Jul, so the Moon is waxing: Shukla paksha.

The night of Thu 28 Jul ran from sunset 19:34 Thu to sunrise 04:18, 8 h 44 m. Cut into 15 muhurtas of 34 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:18 to 19:33, 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, 19:33 to 04:19 Sat, splits into 8 choghadiyas of 1 h 5 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 2 at 243°20′. It leaves at 19:53, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 102.2° + 245.2° = 347.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 02:47 Sat, then Vishkambha.

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 ended at 18:07 Thu, when the lead reached 138°; Balava runs until 06:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:18 to 04:19 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 05:30 Mon to 16 Aug 12:47 Tue the Sun stayed in Karka, entering Simha at 16 Aug 18:28 Tue, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 18 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 1966, 05:46 Tue. Since then the Sun has moved 124.5° round the stars. Vikram Samvat numbers that year 2023; Shaka Samvat numbers it 1888.
