Panchang in Codcod, Western Visayas, Philippines Sat 10 Mar 1956

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 20:19 on Sat 10 Mar to 21:14 on Sun 11 Mar, so only Saturday night’s nishitha (23:33–00:21 Sun) falls within it.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:51 on Fri 9 Mar to 20:19 on Sat 10 Mar, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Sat 10 Mar. 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:57 here. Dwadashi ended at 18:51 Fri, before it. Trayodashi ends at 20:19, when the lead reaches 336°. The lead passed 180° at the full moon of 26 Feb, so the Moon is waning: Krishna paksha.

The night of Fri 9 Mar ran from sunset 17:57 Fri to sunrise 05:57, 12 h 0 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:57 to 17:57, 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, 17:57 to 05:56 Sun, 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 1 at 293°20′. It leaves at 04:01 Sun, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 326.1° + 295.3° = 621.4°, one full turn and 261.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 15:33, then Siddha.

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 07:39, when the lead reaches 330°; Vanija until 20:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:57 to 05:56 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 12 Mar, 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 12 Mar, 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: 24 Mar 1955, 11:42 Thu. Since then the Sun has moved 346.6° round the stars. Vikram Samvat numbers that year 2012; Shaka Samvat numbers it 1877.
