Panchang in Sofia, Sofia-Capital, Bulgaria Sun 5 Jan 2031

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 12:32 on Sun 5 Jan to 15:17 on Mon 6 Jan, so only Sunday’s pradosha (17:07–20:05) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

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, 07:57 here. Ekadashi ended at 09:50 Sat, before it. Dwadashi ends at 12:32, when the lead reaches 144°. The lead passed 0° at the new moon of 24 Dec, so the Moon is waxing: Shukla paksha.

The night of Sat 4 Jan ran from sunset 17:06 Sat to sunrise 07:57, 14 h 51 m. Cut into 15 muhurtas of 59 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:57 to 17:07, splits into 8 choghadiyas of 1 h 8 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:07 to 07:57 Mon, splits into 8 choghadiyas of 1 h 51 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 1 at 40°. It leaves at 06:21 Mon, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 260.4° + 42.3° = 302.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 15:20, then Shukla.

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 ended at 23:10 Sat, when the lead reached 138°; Balava runs until 12:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:57 to 07:57 Mon, so the hours after midnight still belong to Raviwara.

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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 23 Jan, finds it in Makara and begins Magha.

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 24 Dec, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

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 271.5° round the stars. Vikram Samvat numbers that year 2087; Shaka Samvat numbers it 1952.
