Panchang in Codcod, Western Visayas, Philippines Fri 16 Jun 2000

Purnima follows the tithi at sunrise. Purnima holds both sunrises, 05:25 on Fri 16 Jun and 05:25 on Sat 17 Jun. Over two sunrises the Nirnayasindhu takes the first: Fri 16 Jun. 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, 05:25 here. Chaturdashi ended at 04:12, before it. Purnima ends at 06:27 Sat, when the lead reaches 180°. The lead passed 0° at the new moon of 2 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 04:12, before sunrise at 05:25, and ends at 06:27 Sat, after the next sunrise at 05:25 Sat. Both days read Purnima: it is a vriddhi tithi here.

The night of Thu 15 Jun ran from sunset 18:09 Thu to sunrise 05:25, 11 h 16 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 18:10, 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, 18:10 to 05:25 Sat, 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 1 at 226°40′. It leaves at 02:01 Sat, for Mula.

Add the Sun's and the Moon's places among the stars: 61.2° + 229.8° = 291°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 09:50, then Shubha.

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 17:17, when the lead reaches 174°; Bava until 06:27 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:25 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 2 Jul, finds it in Mithuna and begins Ashadha.

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 2 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 2000, 02:12 Wed. Since then the Sun has moved 69.8° round the stars. Vikram Samvat numbers that year 2057; Shaka Samvat numbers it 1922.
