Panchang in Codcod, Western Visayas, Philippines Fri 9 Sep 2033

The first shraddha of Pitru Paksha is done in aparahna, the fourth fifth of the day. Pratipada runs from 10:20 on Fri 9 Sep to 06:45 on Sat 10 Sep, so only Friday’s aparahna (12:57–15:24) falls within it. No text giving Pitru Paksha begins’s time was found; aparahna is Tithika’s convention.

Pitru Paksha begins: every date in Codcod

Purnima follows the tithi at sunrise. Purnima runs from 13:46 on Thu 8 Sep to 10:20 on Fri 9 Sep, so it holds sunrise only on Fri 9 Sep, at 05:37. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 05:37 here. Chaturdashi ended at 13:46 Thu, before it. Purnima ends at 10:20, when the lead reaches 180°. The lead passed 0° at the new moon of 25 Aug, so the Moon is waxing: Shukla paksha.

The night of Thu 8 Sep ran from sunset 17:52 Thu to sunrise 05:37, 11 h 45 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 17:51, 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, 17:51 to 05:37 Sat, 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 4 at 316°40′. It leaves at 06:29, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 142.2° + 319.5° = 461.7°, one full turn and 101.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 13:06, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 00:05, when the lead reached 174°; Bava runs until 10:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 Sat, so the hours after midnight still belong to Shukrawara.

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, 23 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 25 Aug, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 2033, 01:51 Thu. Since then the Sun has moved 156.2° round the stars. Vikram Samvat numbers that year 2090; Shaka Samvat numbers it 1955.
