Panchang in Sevan, Gegharkunik, Armenia Tue 29 May 2068

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 11:18 on Tue 29 May to 09:29 on Wed 30 May, so only Tuesday night’s nishitha (00:39 Wed–01:15 Wed) 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, 05:32 here. Dwadashi ended at 13:24 Mon, before it. Trayodashi ends at 11:18, when the lead reaches 336°. The lead passed 180° at the full moon of 17 May, so the Moon is waning: Krishna paksha.

The night of Mon 28 May ran from sunset 20:21 Mon to sunrise 05:32, 9 h 11 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 20:22, 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, 20:22 to 05:32 Wed, splits into 8 choghadiyas of 1 h 8 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 22:49, for Krittika.

Add the Sun's and the Moon's places among the stars: 43.7° + 16.6° = 60.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 15:43, then Atiganda.

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 00:19, when the lead reached 330°; Vanija runs until 11:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:32 Wed, so the hours after midnight still belong to Mangalawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 31 May, finds it in Vrishabha and begins Jyeshtha.

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 31 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 2 Apr 2068, 12:52 Mon. Since then the Sun has moved 55.1° round the stars. Vikram Samvat numbers that year 2125; Shaka Samvat numbers it 1990.
