Panchang in Pāthardi, Maharashtra Sun 11 Feb 1934

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 15:55 on Sun 11 Feb to 12:40 on Mon 12 Feb, so only Sunday’s pradosha (18:27–20:57) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:00 here. Ekadashi ended at 19:01 Sat, before it. Dwadashi ends at 15:55, when the lead reaches 324°. The lead passed 180° at the full moon of 30 Jan, so the Moon is waning: Krishna paksha.

The night of Sat 10 Feb ran from sunset 18:26 Sat to sunrise 07:00, 12 h 34 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:00 to 18:27, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:27 to 06:59 Mon, splits into 8 choghadiyas of 1 h 34 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 2 at 256°40′. It leaves at 21:43, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 298.7° + 257.6° = 556.3°, one full turn and 196.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 12:39, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 05:30, when the lead reached 318°; Taitila runs until 15:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:00 to 06:59 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 14 Feb, finds it in Kumbha and begins Phalguna.

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 14 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 1933, 08:50 Sun. Since then the Sun has moved 316.6° round the stars. Vikram Samvat numbers that year 1990; Shaka Samvat numbers it 1855.
