Panchang in Myjava, Trenčín Region, Slovakia Wed 5 Nov 1980

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 16:51 on Wed 5 Nov to 19:21 on Thu 6 Nov, so only Wednesday night’s nishitha (23:05–00:02 Thu) 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, 06:42 here. Dwadashi ended at 14:15 Tue, before it. Trayodashi ends at 16:51, when the lead reaches 336°. The lead passed 180° at the full moon of 23 Oct, so the Moon is waning: Krishna paksha.

The night of Tue 4 Nov ran from sunset 16:24 Tue to sunrise 06:42, 14 h 18 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 16:23, splits into 8 choghadiyas of 1 h 12 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:23 to 06:44 Thu, splits into 8 choghadiyas of 1 h 47 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 4 at 170°. It leaves at 11:50, for Chitra.

Add the Sun's and the Moon's places among the stars: 199.4° + 170.8° = 370.2°, one full turn and 10.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 12:35, then Priti.

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 03:33, when the lead reached 330°; Vanija runs until 16:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:44 Thu, so the hours after midnight still belong to Budhawara.

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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 7 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 19:55 Sun. Since then the Sun has moved 226.6° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
