Panchang in Sevan, Gegharkunik, Armenia Sat 14 Jul 2091

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 18:42 on Sat 14 Jul to 18:45 on Sun 15 Jul, so only Saturday night’s nishitha (00:47 Sun–01:24 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:41 here. Dwadashi ended at 18:04 Fri, before it. Trayodashi ends at 18:42, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Jul, so the Moon is waning: Krishna paksha.

The night of Fri 13 Jul ran from sunset 20:30 Fri to sunrise 05:41, 9 h 11 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 20:29, splits into 8 choghadiyas of 1 h 51 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:29 to 05:42 Sun, splits into 8 choghadiyas of 1 h 9 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 00:57 Sun, for Ardra.

Add the Sun's and the Moon's places among the stars: 86.8° + 56.4° = 143.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 11:42, then Dhruva.

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 06:27, when the lead reaches 330°; Vanija until 18:42.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:42 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jun 06:42 Sun to 16 Jul 18:17 Mon the Sun stayed in Mithuna, entering Karka at 17 Jul 13:52 Tue, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 Jul, with the Sun in Mithuna, begins Ashadha (Adhik). Until then this Krishna paksha reads Ashadha (Adhik) here, and Ashadha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2091, 07:47 Tue. Since then the Sun has moved 112.1° round the stars. Vikram Samvat numbers that year 2148; Shaka Samvat numbers it 2013.
