Panchang in Sevan, Gegharkunik, Armenia Fri 13 Jun 2064

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 01:58 on Fri 13 Jun to 02:25 on Sat 14 Jun, so only Friday night’s nishitha (00:42 Sat–01:18 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:29 here. Trayodashi ended at 01:58, before it. Chaturdashi ends at 02:25 Sat, when the lead reaches 348°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

The night of Thu 12 Jun ran from sunset 20:31 Thu 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 Sat, 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 3 at 33°20′. It leaves at 13:25, for Rohini.

Add the Sun's and the Moon's places among the stars: 58.1° + 35.8° = 93.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 03:48 Sat, then Shula.

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 14:16, when the lead reaches 342°; Shakuni until 02:25 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:29 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 16 May 13:55 Fri to 15 Jun 02:21 Sun the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 05:06 Sun, 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 2064, 05:45 Tue. Since then the Sun has moved 84.6° round the stars. Vikram Samvat numbers that year 2121; Shaka Samvat numbers it 1986.
