Panchang in Sofia, Sofia-Capital, Bulgaria Mon 12 Mar 2029

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:12 on Mon 12 Mar to 02:00 on Tue 13 Mar, so only Monday’s pradosha (18:29–20:56) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sofia

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, 06:43 here. Dwadashi ended at 00:12, before it. Trayodashi ends at 02:00 Tue, when the lead reaches 336°. The lead passed 180° at the full moon of 28 Feb, so the Moon is waning: Krishna paksha.

The night of Sun 11 Mar ran from sunset 18:28 Sun to sunrise 06:43, 12 h 15 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 18:29, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:29 to 06:42 Tue, splits into 8 choghadiyas of 1 h 31 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 1 at 293°20′. It leaves at 06:27 Tue, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 327.6° + 294.7° = 622.3°, one full turn and 262.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 14:41, 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 13:04, when the lead reaches 330°; Vanija until 02:00 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:42 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 15 Mar, finds it in Meena and begins Chaitra.

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 15 Mar, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 2028, 07:31 Sun. Since then the Sun has moved 345.8° round the stars. Vikram Samvat numbers that year 2085; Shaka Samvat numbers it 1950.
