Panchang in Codcod, Western Visayas, Philippines Sun 2 Nov 1975

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi runs from 03:38 on Sun 2 Nov to 00:17 on Mon 3 Nov, so only Sunday’s arunodaya (04:02–05:38) falls within it. No text giving Narak Chaturdashi’s time was found; arunodaya is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 03:38 on Sun 2 Nov to 00:17 on Mon 3 Nov, so only Sunday night’s nishitha (23:06–23:55) falls within it. 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:38 here. Trayodashi ended at 03:38, before it. Chaturdashi ends at 00:17 Mon, when the lead reaches 348°. The lead passed 180° at the full moon of 20 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 1 Nov ran from sunset 17:23 Sat 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 17:23, 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, 17:23 to 05:38 Mon, 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 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 4 at 170°. It leaves at 07:00, for Chitra.

Add the Sun's and the Moon's places among the stars: 195.3° + 172.5° = 367.8°, one full turn and 7.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 13:57, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti runs until 13:57, when the lead reaches 342°; Shakuni until 00:17 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:38 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 3 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 3 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: 12 Apr 1975, 00:38 Sat. Since then the Sun has moved 197.6° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
