Panchang in Codcod, Western Visayas, Philippines Thu 27 Mar 1975

Holika is burnt in pradosha, the 3 muhurtas after sunset, outside bhadra. Purnima runs from 22:15 on Wed 26 Mar to 18:36 on Thu 27 Mar, so it touches only Thursday’s pradosha (17:57–20:19).

Holika Dahan: every date in Codcod

Purnima follows the tithi at sunrise. Purnima runs from 22:15 on Wed 26 Mar to 18:36 on Thu 27 Mar, so it holds sunrise only on Thu 27 Mar, at 05:47. 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, 05:47 here. Chaturdashi ended at 22:15 Wed, before it. Purnima ends at 18:36, when the lead reaches 180°. The lead passed 0° at the new moon of 13 Mar, so the Moon is waxing: Shukla paksha.

The night of Wed 26 Mar ran from sunset 17:57 Wed to sunrise 05:47, 11 h 50 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:47 to 17:57, 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, 17:57 to 05:47 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 3 at 153°20′. It leaves at 14:25, for Hasta.

Add the Sun's and the Moon's places among the stars: 342.1° + 154.6° = 496.7°, one full turn and 136.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 20:43, then Dhruva.

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 08:24, when the lead reaches 174°; Bava until 18:36.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:47 to 05:47 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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 12 Apr, finds it in Meena and begins Chaitra.

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 13 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1974, 05:23 Sun. Since then the Sun has moved 362.7° round the stars. Vikram Samvat numbers that year 2031; Shaka Samvat numbers it 1896.
