Panchang in Myjava, Trenčín Region, Slovakia Sat 3 Jun 1978

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 16:49 on Sat 3 Jun to 18:16 on Sun 4 Jun, so only Saturday night’s nishitha (23:31–00:03 Sun) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Myjava

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, 03:49 here. Dwadashi ended at 15:43 Fri, before it. Trayodashi ends at 16:49, when the lead reaches 336°. The lead passed 180° at the full moon of 22 May, so the Moon is waning: Krishna paksha.

The night of Fri 2 Jun ran from sunset 19:44 Fri to sunrise 03:49, 8 h 5 m. Cut into 15 muhurtas of 32 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 03:49 to 19:45, splits into 8 choghadiyas of 1 h 59 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:45 to 03:49 Sun, splits into 8 choghadiyas of 1 h 0 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 2 at 16°40′. It leaves at 19:46, for Krittika.

Add the Sun's and the Moon's places among the stars: 48.6° + 18.4° = 67°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 03:08 Sun, then Sukarma.

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 04:13, when the lead reaches 330°; Vanija until 16:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 03:49 to 03:49 Sun, so the hours after midnight still belong to Shaniwara.

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, 5 Jun, 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 5 Jun, 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: 7 Apr 1978, 16:15 Fri. Since then the Sun has moved 54.7° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
