Panchang in Myjava, Trenčín Region, Slovakia Mon 29 Jul 1985

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:12 on Mon 29 Jul to 02:23 on Tue 30 Jul, so only Monday’s pradosha (20:32–22:17) 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: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 05:18 here. Dwadashi ended at 04:12, before it. Trayodashi ends at 02:23 Tue, when the lead reaches 156°. The lead passed 0° at the new moon of 18 Jul, so the Moon is waxing: Shukla paksha.

The night of Sun 28 Jul ran from sunset 20:33 Sun to sunrise 05:18, 8 h 45 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:18 to 20:32, 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, 20:32 to 05:20 Tue, 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 3 at 246°40′. It leaves at 16:21, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 102.3° + 246.9° = 349.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 22:40, then Vishkambha.

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 15:16, when the lead reaches 150°; Taitila until 02:23 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:18 to 05:20 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 01:56 Thu to 16 Aug 12:05 Fri the Sun stayed in Karka, entering Simha at 16 Aug 16:23 Fri, 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: 21 Mar 1985, 12:58 Thu. Since then the Sun has moved 125.1° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
