Panchang in Myjava, Trenčín Region, Slovakia Fri 30 Jul 1909

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:02 on Fri 30 Jul to 02:44 on Sat 31 Jul, so only Friday’s pradosha (19:31–21:17) 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, 04:19 here. Dwadashi ended at 04:02, before it. Trayodashi ends at 02:44 Sat, when the lead reaches 156°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

The night of Thu 29 Jul ran from sunset 19:33 Thu to sunrise 04:19, 8 h 46 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:19 to 19:31, 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, 19:31 to 04:20 Sat, 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 14:01, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 103.7° + 247.9° = 351.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 18:14, 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 15:28, when the lead reaches 150°; Taitila until 02:44 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:19 to 04:20 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 17 Jul 11:44 Sat to 16 Aug 00:54 Mon the Sun stayed in Karka, entering Simha at 16 Aug 04:05 Mon, 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 17 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 1909, 21:11 Sun. Since then the Sun has moved 125.7° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
