Panchang in Codcod, Western Visayas, Philippines Wed 3 May 1989

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:18 on Wed 3 May to 02:52 on Thu 4 May, so only Wednesday’s pradosha (17:59–20:17) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 02:52 on Thu 4 May to 23:18 on Thu 4 May, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Wed 3 May. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 05:28 here. Ekadashi ended at 09:27 Tue, before it. Dwadashi ends at 06:18, when the lead reaches 324°. The lead passed 180° at the full moon of 21 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:18 and ended at 02:52 Thu, between the sunrises of 05:28 and 05:28 Thu. Wednesday reads Dwadashi and Thursday reads Chaturdashi: Trayodashi is a kshaya tithi here.

Sunrise here, 05:39, came after Dwadashi ended at 03:48: this day reads Trayodashi.

Codcod · UTC+8

Sunrise here, 05:28, came before Dwadashi ended at 06:18: this day reads Dwadashi. Trayodashi ends at 02:52 Thu, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Tue 2 May ran from sunset 17:59 Tue to sunrise 05:28, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:28 to 17:59, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:59 to 05:28 Thu, splits into 8 choghadiyas of 1 h 26 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 3 at 340°. It leaves at 12:35, for Revati.

Add the Sun's and the Moon's places among the stars: 18.7° + 342.2° = 360.9°, one full turn and 0.9°. 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 00:05 Thu, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 19:55 Tue, when the lead reached 318°; Taitila runs until 06:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:28 to 05:28 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 5 May, finds it in Mesha and begins Vaishakha.

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 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 1989, 11:32 Thu. Since then the Sun has moved 26.1° round the stars. Vikram Samvat numbers that year 2046; Shaka Samvat numbers it 1911.
