Panchang in Pāthardi, Maharashtra Fri 11 Mar 1983

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi began at 18:04 on Fri 11 Mar, before that evening’s pradosha, and ended at 20:14 on Sat 12 Mar, partway into the next. The Nirnayasindhu takes the evening Trayodashi fills: Fri 11 Mar. 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, 06:41 here. Ekadashi ended at 15:33 Thu, before it. Dwadashi ends at 18:04, when the lead reaches 324°. The lead passed 180° at the full moon of 27 Feb, so the Moon is waning: Krishna paksha.

The night of Thu 10 Mar ran from sunset 18:37 Thu to sunrise 06:41, 12 h 4 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 18:37, 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 night here, 18:37 to 06:40 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shravana spans 280°00′–293°20′; the Moon entered its pada 2 at 283°20′. It leaves at 23:16, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 326.3° + 285.1° = 611.4°, one full turn and 251.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 10:19, then Shiva.

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 04:51, when the lead reached 318°; Taitila runs until 18:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:40 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Feb 06:01 Sun to 14 Mar 23:13 Mon the Sun stayed in Kumbha, entering Meena at 15 Mar 00:14 Tue, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna itself.

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 Mar, with the Sun in Kumbha, begins Phalguna (Adhik). Until then this Krishna paksha reads Phalguna (Adhik) here, and Phalguna (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1982, 15:47 Thu. Since then the Sun has moved 345.5° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
