Panchang in Pāthardi, Maharashtra Sat 23 Mar 1963

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:07 on Sat 23 Mar to 00:27 on Sun 24 Mar, so only Saturday’s pradosha (18:40–21:02) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 00:27 on Sun 24 Mar to 21:14 on Sun 24 Mar, so it touches only Saturday night’s nishitha (00:12 Sun–00:59 Sun). No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

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, 06:31 here. Dwadashi ended at 03:07, before it. Trayodashi ends at 00:27 Sun, when the lead reaches 336°. The lead passed 180° at the full moon of 10 Mar, so the Moon is waning: Krishna paksha.

The night of Fri 22 Mar ran from sunset 18:40 Fri to sunrise 06:31, 11 h 51 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:31 to 18:40, 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 night here, 18:40 to 06:30 Sun, 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 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 4 at 303°20′. It leaves at 10:34, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 338.3° + 304.2° = 642.5°, one full turn and 282.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 23:10, then Shubha.

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 13:52, when the lead reaches 330°; Vanija until 00:27 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:31 to 06:30 Sun, so the hours after midnight still belong to Shaniwara.

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, 25 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 25 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: 5 Apr 1962, 01:14 Thu. Since then the Sun has moved 347.1° round the stars. Vikram Samvat numbers that year 2019; Shaka Samvat numbers it 1884.
