Panchang in Ipameri, Goiás, Brazil Sat 2 Oct 1982

Purnima follows the tithi at sunrise. Purnima runs from 22:49 on Fri 1 Oct to 22:08 on Sat 2 Oct, so it holds sunrise only on Sat 2 Oct, at 05:54. 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, 05:54 here. Chaturdashi ended at 22:49 Fri, before it. Purnima ends at 22:08, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Sep, so the Moon is waxing: Shukla paksha.

The night of Fri 1 Oct ran from sunset 18:10 Fri to sunrise 05:54, 11 h 44 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 18:10, splits into 8 choghadiyas of 1 h 32 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 05:53 Sun, splits into 8 choghadiyas of 1 h 27 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 2 at 336°40′. It leaves at 23:31, for Revati.

Add the Sun's and the Moon's places among the stars: 165.2° + 336.8° = 502°, one full turn and 142°. 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 13:37, 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 10:33, when the lead reaches 174°; Bava until 22:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:53 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 09:09 Fri to 16 Oct 21:04 Sat the Sun stayed in Kanya, entering Tula at 17 Oct 04:46 Sun, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina 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 17 Sep, with the Sun in Kanya, began Ashwina (Adhik). This Shukla paksha reads Ashwina (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1982, 07:17 Thu. Since then the Sun has moved 184.4° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
