Panchang in Codcod, Western Visayas, Philippines Fri 30 May 1980

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, 05:23 here. Chaturdashi ended at 04:44 Thu, before it. Purnima ends at 05:27, when the lead reaches 180°. The lead passed 0° at the new moon of 14 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 04:44 Thu, before sunrise at 05:23 Thu, and ends at 05:27, after the next sunrise at 05:23. Both days read Purnima: it is a vriddhi tithi here.

The night of Thu 29 May ran from sunset 18:05 Thu to sunrise 05:23, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:23 to 18:05, 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, 18:05 to 05:23 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 4 at 223°20′. It leaves at 08:30, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 45° + 225° = 270°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 22:43, then Sadhya.

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 17:09 Thu, when the lead reached 174°; Bava runs until 05:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:23 to 05:23 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 May 20:00 Wed to 13 Jun 04:38 Fri the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 20:25 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 14 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1980, 02:55 Mon. Since then the Sun has moved 72.2° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
