Panchang in Sevan, Gegharkunik, Armenia Sat 6 Nov 1999

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi began at 04:38 on Sat 6 Nov, before that morning’s arunodaya, and ended at 06:05 on Sun 7 Nov, partway into the next. The Nirnayasindhu takes the morning Chaturdashi fills: Sat 6 Nov. No text giving Narak Chaturdashi’s time was found; arunodaya is Tithika’s convention.

Narak Chaturdashi: every date in Sevan

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 04:38 on Sat 6 Nov to 06:05 on Sun 7 Nov, so only Saturday night’s nishitha (00:16 Sun–01:11 Sun) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Sevan

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, 07:34 here. Trayodashi ended at 04:38, before it. Chaturdashi ends at 06:05 Sun, when the lead reaches 348°. The lead passed 180° at the full moon of 25 Oct, so the Moon is waning: Krishna paksha.

The night of Fri 5 Nov ran from sunset 17:52 Fri to sunrise 07:34, 13 h 42 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:34 to 17:51, splits into 8 choghadiyas of 1 h 17 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:51 to 07:36 Sun, splits into 8 choghadiyas of 1 h 43 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 2 at 176°40′. It leaves at 02:46 Sun, for Swati.

Add the Sun's and the Moon's places among the stars: 199.4° + 176.8° = 376.2°, one full turn and 16.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 02:22 Sun, then Ayushmana.

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 17:19, when the lead reaches 342°; Shakuni until 06:05 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:34 to 07:36 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 8 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 8 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: 17 Mar 1999, 22:47 Wed. Since then the Sun has moved 226.5° round the stars. Vikram Samvat numbers that year 2056; Shaka Samvat numbers it 1921.
