Panchang in Myjava, Trenčín Region, Slovakia Thu 24 Feb 1983

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:08 on Thu 24 Feb to 16:48 on Fri 25 Feb, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Thu 24 Feb. 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, 06:42 here. Ekadashi ended at 23:13 Wed, before it. Dwadashi ends at 20:08, when the lead reaches 144°. The lead passed 0° at the new moon of 13 Feb, so the Moon is waxing: Shukla paksha.

The night of Wed 23 Feb ran from sunset 17:22 Wed to sunrise 06:42, 13 h 20 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 17:24, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:24 to 06:40 Fri, splits into 8 choghadiyas of 1 h 39 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 15:51, for Pushya.

Add the Sun's and the Moon's places among the stars: 311.4° + 87.7° = 399.1°, one full turn and 39.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 08:02, then Saubhagya.

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 runs until 09:43, when the lead reaches 138°; Balava until 20:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:40 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Feb 01:31 Sun to 14 Mar 18:43 Mon the Sun stayed in Kumbha, entering Meena at 14 Mar 19:44 Mon, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna 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 13 Feb, with the Sun in Kumbha, began Phalguna (Adhik). This Shukla paksha reads Phalguna (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1982, 11:17 Thu. Since then the Sun has moved 330.6° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
