Panchang in Myjava, Trenčín Region, Slovakia Tue 10 Jun 1980

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:44 on Tue 10 Jun to 03:07 on Wed 11 Jun, so only Tuesday’s pradosha (20:51–22:26) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 04:46 here. Ekadashi ended at 08:25 Mon, before it. Dwadashi ends at 05:44, when the lead reaches 324°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 05:44 and ended at 03:07 Wed, between the sunrises of 04:46 and 04:46 Wed. Tuesday reads Dwadashi and Wednesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Mon 9 Jun ran from sunset 20:51 Mon to sunrise 04:46, 7 h 55 m. Cut into 15 muhurtas of 31 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:46 to 20:51, splits into 8 choghadiyas of 2 h 0 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:51 to 04:46 Wed, splits into 8 choghadiyas of 59 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 2 at 16°40′. It leaves at 17:06, for Krittika.

Add the Sun's and the Moon's places among the stars: 55.8° + 19.2° = 75°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 12:29, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 19:04 Mon, when the lead reached 318°; Taitila runs until 05:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:46 to 04:46 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 May 14:00 Wed to 12 Jun 22:38 Thu the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 14:25 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 12 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 19:55 Sun. Since then the Sun has moved 83° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
