Panchang in Codcod, Western Visayas, Philippines Thu 17 Sep 2009

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 08:21 on Thu 17 Sep to 05:27 on Fri 18 Sep, so only Thursday night’s nishitha (23:17–00:05 Fri) falls within it. 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:36 here. Dwadashi ended at 11:18 Wed, before it. Trayodashi ends at 08:21, when the lead reaches 336°. The lead passed 180° at the full moon of 5 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 08:21 and ended at 05:27 Fri, between the sunrises of 05:36 and 05:36 Fri. Thursday reads Trayodashi and Friday reads Amavasya: Chaturdashi is a kshaya tithi here.

Sunrise here, 05:36, came before Trayodashi ended at 08:21: this day reads Trayodashi. Chaturdashi ends at 05:27 Fri, before the next sunrise, so no day here reads Chaturdashi: it is kshaya.

The night of Wed 16 Sep ran from sunset 17:47 Wed to sunrise 05:36, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:46, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:46 to 05:36 Fri, splits into 8 choghadiyas of 1 h 28 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 2 at 123°20′. It leaves at 19:56, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 150.2° + 124.6° = 274.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 13:41, then Sadhya.

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 21:49 Wed, when the lead reached 330°; Vanija runs until 08:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 19 Sep, finds it in Kanya and begins Ashwina.

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 19 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 2009, 00:05 Fri. Since then the Sun has moved 168.1° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
