Panchang in Ipameri, Goiás, Brazil Tue 28 Apr 1953

Purnima follows the tithi at sunrise. Purnima runs from 00:11 on Tue 28 Apr to 01:20 on Wed 29 Apr, so it holds sunrise only on Tue 28 Apr, at 06:25. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Ipameri

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, 06:25 here. Chaturdashi ended at 00:11, before it. Purnima ends at 01:20 Wed, when the lead reaches 180°. The lead passed 0° at the new moon of 13 Apr, so the Moon is waxing: Shukla paksha.

The night of Mon 27 Apr ran from sunset 17:55 Mon to sunrise 06:25, 12 h 30 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:25 to 17:55, 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 night here, 17:55 to 06:25 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 08:37, for Swati.

Add the Sun's and the Moon's places among the stars: 14.6° + 185.5° = 200.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 06:01 Wed, then Vyatipata.

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 12:49, when the lead reaches 174°; Bava until 01:20 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:25 to 06:25 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Apr 17:08 Mon to 13 May 02:05 Wed the Sun stayed in Mesha, entering Vrishabha at 14 May 04:41 Thu, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 13 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1953, 08:04 Sun. Since then the Sun has moved 43.2° round the stars. Vikram Samvat numbers that year 2010; Shaka Samvat numbers it 1875.
