Panchang in Myshkin, Yaroslavl Oblast, Russia Mon 26 Aug 2030

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:47 on Mon 26 Aug to 02:31 on Tue 27 Aug, so only Monday’s pradosha (19:40–21:35) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Myshkin

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, 05:13 here. Dwadashi ended at 01:47, before it. Trayodashi ends at 02:31 Tue, when the lead reaches 336°. The lead passed 180° at the full moon of 13 Aug, so the Moon is waning: Krishna paksha.

The night of Sun 25 Aug ran from sunset 19:43 Sun to sunrise 05:13, 9 h 30 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:13 to 19:40, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:40 to 05:15 Tue, splits into 8 choghadiyas of 1 h 11 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 04:45 Tue, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 128.6° + 94.3° = 222.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 11:55, then Variyana.

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 14:14, when the lead reaches 330°; Vanija until 02:31 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:13 to 05:15 Tue, so the hours after midnight still belong to Somawara.

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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 29 Aug, finds it in Simha and begins Bhadrapada.

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 29 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 2030, 01:02 Wed. Since then the Sun has moved 139.7° round the stars. Vikram Samvat numbers that year 2087; Shaka Samvat numbers it 1952.
