Panchang in Sevan, Gegharkunik, Armenia Wed 13 Jun 2007

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 14:08 on Wed 13 Jun to 11:04 on Thu 14 Jun, so only Wednesday night’s nishitha (01:42 Thu–02:17 Thu) 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 06:28 here. Dwadashi ended at 17:16 Tue, before it. Trayodashi ends at 14:08, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Jun, so the Moon is waning: Krishna paksha.

The night of Tue 12 Jun ran from sunset 21:30 Tue to sunrise 06:28, 8 h 58 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:28 to 21:31, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:31 to 06:28 Thu, splits into 8 choghadiyas of 1 h 7 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 1 at 26°40′. It leaves at 23:50, for Rohini.

Add the Sun's and the Moon's places among the stars: 57.7° + 29.3° = 87°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 16:03, then Dhriti.

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 ended at 03:42, when the lead reached 330°; Vanija runs until 14:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:28 to 06:28 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 May 00:27 Thu to 15 Jun 08:13 Fri the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 15:22 Fri, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 15 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 83.5° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
