Panchang in Sevan, Gegharkunik, Armenia Sun 13 Jun 2083

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 09:01 on Sun 13 Jun to 11:24 on Mon 14 Jun, so only Sunday night’s nishitha (00:42 Mon–01:18 Mon) 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, 05:29 here. Dwadashi ended at 06:35 Sat, before it. Trayodashi ends at 09:01, when the lead reaches 336°. The lead passed 180° at the full moon of 31 May, so the Moon is waning: Krishna paksha.

The night of Sat 12 Jun ran from sunset 20:31 Sat to sunrise 05:29, 8 h 58 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 20:31, 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, 20:31 to 05:29 Mon, 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 2 at 30°. It leaves at 22:20, for Rohini.

Add the Sun's and the Moon's places among the stars: 57.3° + 31.7° = 89°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 13:41, 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 19:48 Sat, when the lead reached 330°; Vanija runs until 09:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:29 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 May 22:15 Sun to 15 Jun 13:39 Tue the Sun stayed in Vrishabha, entering Mithuna at 16 Jun 01:47 Wed, 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: 18 Mar 2083, 13:58 Thu. Since then the Sun has moved 84.3° round the stars. Vikram Samvat numbers that year 2140; Shaka Samvat numbers it 2005.
