Panchang in Codcod, Western Visayas, Philippines Fri 14 Feb 2014

Purnima follows the tithi at sunrise. Purnima holds both sunrises, 06:07 on Fri 14 Feb and 06:07 on Sat 15 Feb. Over two sunrises the Nirnayasindhu takes the first: Fri 14 Feb. 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, 06:07 here. Chaturdashi ended at 05:39, before it. Purnima ends at 07:53 Sat, when the lead reaches 180°. The lead passed 0° at the new moon of 31 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 05:39, before sunrise at 06:07, and ends at 07:53 Sat, after the next sunrise at 06:07 Sat. Both days read Purnima: it is a vriddhi tithi here.

The night of Thu 13 Feb ran from sunset 17:54 Thu to sunrise 06:07, 12 h 13 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:07 to 17:55, 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 night here, 17:55 to 06:07 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 03:35 Sat, for Magha.

Add the Sun's and the Moon's places among the stars: 301.1° + 109.3° = 410.4°, one full turn and 50.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 11:38, then Shobhana.

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 18:48, when the lead reaches 174°; Bava until 07:53 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:07 to 06:07 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 1 Mar, finds it in Kumbha and begins Phalguna.

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 31 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 17:35 Wed. Since then the Sun has moved 304.5° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
