Panchang in Khmelnytskyi, Ukraine Tue 28 Aug 2012

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:17 on Tue 28 Aug to 18:49 on Wed 29 Aug, so it touches only Tuesday’s pradosha (20:02–22:07). No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Khmelnytskyi

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, 06:22 here. Ekadashi ended at 21:58 Mon, before it. Dwadashi ends at 20:17, when the lead reaches 144°. The lead passed 0° at the new moon of 17 Aug, so the Moon is waxing: Shukla paksha.

The night of Mon 27 Aug ran from sunset 20:04 Mon to sunrise 06:22, 10 h 18 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 20:02, splits into 8 choghadiyas of 1 h 42 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:02 to 06:23 Wed, splits into 8 choghadiyas of 1 h 17 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 03:40 Wed, for Shravana.

Add the Sun's and the Moon's places among the stars: 131.2° + 267.7° = 398.9°, one full turn and 38.9°. 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 08:06, 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 09:06, when the lead reaches 138°; Balava until 20:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:23 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 17 Aug 18:54 Fri to 16 Sep 05:10 Sun the Sun stayed in Simha, entering Kanya at 16 Sep 15:24 Sun, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 16:37 Thu. Since then the Sun has moved 152.9° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
