Panchang in Codcod, Western Visayas, Philippines Mon 2 Jun 1997

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:53 on Mon 2 Jun to 17:17 on Tue 3 Jun, so it touches only Monday’s pradosha (18:06–20:21). No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Codcod

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, 05:24 here. Ekadashi ended at 20:42 Sun, before it. Dwadashi ends at 18:53, when the lead reaches 324°. The lead passed 180° at the full moon of 22 May, so the Moon is waning: Krishna paksha.

The night of Sun 1 Jun ran from sunset 18:05 Sun 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 18:06, 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, 18:06 to 05:24 Tue, 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 2 at 3°20′. It leaves at 20:59, for Bharani.

Add the Sun's and the Moon's places among the stars: 47.6° + 4.3° = 51.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 07:44, then Shobhana.

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 runs until 07:46, when the lead reaches 318°; Taitila until 18:53.

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

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 1997, 19:01 Mon. Since then the Sun has moved 53.7° round the stars. Vikram Samvat numbers that year 2054; Shaka Samvat numbers it 1919.
