Panchang in Codcod, Western Visayas, Philippines Thu 22 Aug 2002

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 05:09 on Thu 22 Aug to 06:29 on Fri 23 Aug, so only Thursday’s aparahna (13:04–15:33) falls within it. Bhadra lasts until 17:46, and the Dharmasindhu keeps the rite out of bhadra: it is done from 17:46. Every reading takes that day.

Raksha Bandhan muhurat: the time after bhadra, at 17:46.

Raksha Bandhan: every date in Codcod

Purnima follows the tithi at sunrise. Purnima holds both sunrises, 05:37 on Thu 22 Aug and 05:37 on Fri 23 Aug. Over two sunrises the Nirnayasindhu takes the first: Thu 22 Aug. 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 05:09, before it. Purnima ends at 06:29 Fri, when the lead reaches 180°. The lead passed 0° at the new moon of 9 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 05:09, before sunrise at 05:37, and ends at 06:29 Fri, after the next sunrise at 05:37 Fri. Both days read Purnima: it is a vriddhi tithi here.

The night of Wed 21 Aug ran from sunset 18:02 Wed to sunrise 05:37, 11 h 35 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 18:02, 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, 18:02 to 05:37 Fri, 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 4 at 290°. It leaves at 06:17, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 124.8° + 293° = 417.8°, one full turn and 57.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 21:42, then Atiganda.

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 runs until 17:46, when the lead reaches 174°; Bava until 06:29 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 7 Sep, finds it in Simha and begins Bhadrapada.

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 9 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Apr 2002, 03:21 Sat. Since then the Sun has moved 126° round the stars. Vikram Samvat numbers that year 2059; Shaka Samvat numbers it 1924.
