Panchang in Myjava, Trenčín Region, Slovakia Thu 13 Sep 1917

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:02 on Thu 13 Sep to 07:35 on Fri 14 Sep, so only Thursday’s pradosha (19:08–21:23) 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 06:22 here. Dwadashi ended at 05:02, before it. Trayodashi ends at 07:35 Fri, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 05:02, before sunrise at 06:22, and ends at 07:35 Fri, after the next sunrise at 06:23 Fri. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Wed 12 Sep ran from sunset 19:10 Wed to sunrise 06:22, 11 h 12 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 19:08, splits into 8 choghadiyas of 1 h 35 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 2 at 110°. It leaves at 23:14, for Magha.

Add the Sun's and the Moon's places among the stars: 147.1° + 111.7° = 258.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 21:10, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 18:18, when the lead reaches 330°; Vanija until 07:35 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:23 Fri, so the hours after midnight still belong to Guruwara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 16 Sep, finds it in Kanya and begins Ashwina.

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 16 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1917, 05:04 Fri. Since then the Sun has moved 167.8° round the stars. Vikram Samvat numbers that year 1974; Shaka Samvat numbers it 1839.
