Panchang in Sevan, Gegharkunik, Armenia Fri 20 Oct 2006

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi began at 05:21 on Fri 20 Oct, before that morning’s arunodaya, and ended at 07:55 on Sat 21 Oct, partway into the next. The Nirnayasindhu takes the morning Chaturdashi fills: Fri 20 Oct. 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 05:21 on Fri 20 Oct to 07:55 on Sat 21 Oct, so only Friday night’s nishitha (01:18 Sat–02:11 Sat) 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, 08:15 here. Trayodashi ended at 05:21, before it. Chaturdashi ends at 07:55 Sat, when the lead reaches 348°. The lead passed 180° at the full moon of 7 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 19 Oct ran from sunset 19:14 Thu to sunrise 08:15, 13 h 1 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:15 to 19:13, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:13 to 08:17 Sat, splits into 8 choghadiyas of 1 h 38 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 08:21, for Hasta.

Add the Sun's and the Moon's places among the stars: 182.6° + 159.9° = 342.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 15:54, then Vaidhriti.

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 18:39, when the lead reaches 342°; Shakuni until 07:55 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:15 to 08:17 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, 22 Oct, 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 22 Oct, 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: 29 Mar 2006, 15:15 Wed. Since then the Sun has moved 198° round the stars. Vikram Samvat numbers that year 2063; Shaka Samvat numbers it 1928.
