Panchang in Sevan, Gegharkunik, Armenia Fri 14 Aug 2099

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 19:08 on Fri 14 Aug to 16:12 on Sat 15 Aug, so only Friday night’s nishitha (00:44 Sat–01:25 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 06:09 here. Dwadashi ended at 21:32 Thu, before it. Trayodashi ends at 19:08, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Aug, so the Moon is waning: Krishna paksha.

The night of Thu 13 Aug ran from sunset 20:00 Thu to sunrise 06:09, 10 h 9 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 19:58, 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 night here, 19:58 to 06:10 Sat, splits into 8 choghadiyas of 1 h 16 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 2 at 83°20′. It leaves at 19:47, for Pushya.

Add the Sun's and the Moon's places among the stars: 116.4° + 85.2° = 201.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 00:29 Sat, then Vyatipata.

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 08:24, when the lead reaches 330°; Vanija until 19:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:10 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 05:02 Sat to 16 Aug 12:56 Sun the Sun stayed in Karka, entering Simha at 17 Aug 23:30 Mon, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 16 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2099, 02:48 Sun. Since then the Sun has moved 140° round the stars. Vikram Samvat numbers that year 2156; Shaka Samvat numbers it 2021.
