Panchang in Codcod, Western Visayas, Philippines Thu 1 Jun 2000

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 02:45 on Thu 1 Jun to 23:39 on Thu 1 Jun, so it touches only Thursday night’s nishitha (23:22–00:07 Fri). No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Codcod

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, 05:24 here. Trayodashi ended at 02:45, before it. Chaturdashi ends at 23:39, when the lead reaches 348°. The lead passed 180° at the full moon of 18 May, so the Moon is waning: Krishna paksha.

The night of Wed 31 May ran from sunset 18:05 Wed to sunrise 05:24, 11 h 19 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:24 to 18:05, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:05 to 05:24 Fri, splits into 8 choghadiyas of 1 h 24 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 4 at 23°20′. It leaves at 09:11, for Krittika.

Add the Sun's and the Moon's places among the stars: 46.8° + 24.3° = 71.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 18:52, then Sukarma.

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 13:15, when the lead reaches 342°; Shakuni until 23:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:24 to 05:24 Fri, so the hours after midnight still belong to Guruwara.

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, 2 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 2 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: 5 Apr 2000, 02:12 Wed. Since then the Sun has moved 55.4° round the stars. Vikram Samvat numbers that year 2057; Shaka Samvat numbers it 1922.
