Panchang in Codcod, Western Visayas, Philippines Fri 3 Nov 1972

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:10 on Fri 3 Nov to 04:57 on Sat 4 Nov, so only Friday’s pradosha (17:22–19:50) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:10 on Fri 3 Nov to 04:57 on Sat 4 Nov, so only Friday’s pradosha (17:22–19:50) falls within it. 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, 05:38 here. Dwadashi ended at 03:10, before it. Trayodashi ends at 04:57 Sat, when the lead reaches 336°. The lead passed 180° at the full moon of 22 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 2 Nov ran from sunset 17:23 Thu to sunrise 05:38, 12 h 15 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:38 to 17:22, 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 night here, 17:22 to 05:38 Sat, splits into 8 choghadiyas of 1 h 32 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 03:31 Sat, for Chitra.

Add the Sun's and the Moon's places among the stars: 197.1° + 162.2° = 359.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 06:51, then Vishkambha.

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 16:01, when the lead reaches 330°; Vanija until 04:57 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:38 Sat, so the hours after midnight still belong to Shukrawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 6 Nov, finds it in Tula and begins Kartika.

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 6 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 19:34 Wed. Since then the Sun has moved 225.6° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
