Panchang in Sevan, Gegharkunik, Armenia Wed 11 Jun 1980

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 05:07 on Wed 11 Jun to 02:42 on Thu 12 Jun, so only Wednesday night’s nishitha (00:41 Thu–01:17 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:28 here. Trayodashi ended at 05:07, before it. Chaturdashi ends at 02:42 Thu, when the lead reaches 348°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:22, came before Trayodashi ended at 06:37: this day reads Trayodashi. Chaturdashi ends at 04:12 Thu, before the next sunrise, so no day here reads Chaturdashi: it is kshaya.

Sunrise here, 05:28, came after Trayodashi ended at 05:07: this day reads Chaturdashi.

The night of Tue 10 Jun ran from sunset 20:29 Tue to sunrise 05:28, 8 h 59 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:28 to 20:30, 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, 20:30 to 05:28 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 2 at 30°. It leaves at 17:22, for Rohini.

Add the Sun's and the Moon's places among the stars: 56.7° + 32.9° = 89.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 11:20, then Dhriti.

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 15:53, when the lead reaches 342°; Shakuni until 02:42 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:28 to 05:28 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 14 May 16:00 Wed to 13 Jun 00:38 Fri the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 16:25 Sat, 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 13 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: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 83.9° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
