Panchang in Pāthardi, Maharashtra Sun 19 Mar 1989

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:03 on Sun 19 Mar to 10:21 on Mon 20 Mar, so only Sunday’s pradosha (18:39–21:02) 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: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 06:34 here. Ekadashi ended at 06:06 Sat, before it. Dwadashi ends at 08:03, when the lead reaches 144°. The lead passed 0° at the new moon of 7 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dwadashi began at 06:06 Sat, before sunrise at 06:35 Sat, and ends at 08:03, after the next sunrise at 06:34. Both days read Dwadashi: it is a vriddhi tithi here.

The night of Sat 18 Mar ran from sunset 18:39 Sat to sunrise 06:34, 11 h 55 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 18:39, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:39 to 06:33 Mon, splits into 8 choghadiyas of 1 h 29 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 10:32, for Magha.

Add the Sun's and the Moon's places among the stars: 334.7° + 118° = 452.7°, one full turn and 92.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 07:42, then Dhriti.

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 19:02 Sat, when the lead reached 138°; Balava runs until 08:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:33 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 6 Apr, 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 7 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1988, 07:32 Fri. Since then the Sun has moved 360.7° round the stars. Vikram Samvat numbers that year 2045; Shaka Samvat numbers it 1910.
