Panchang in Ipameri, Goiás, Brazil Tue 18 Nov 1975

Kartik Purnima follows the tithi at sunrise. Purnima runs from 18:04 on Mon 17 Nov to 19:28 on Tue 18 Nov, so it holds sunrise only on Tue 18 Nov, at 05:28. No text giving Kartik 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, 05:28 here. Chaturdashi ended at 18:04 Mon, before it. Purnima ends at 19:28, when the lead reaches 180°. The lead passed 0° at the new moon of 3 Nov, so the Moon is waxing: Shukla paksha.

The night of Mon 17 Nov ran from sunset 18:26 Mon to sunrise 05:28, 11 h 2 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:28 to 18:27, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:27 to 05:28 Wed, splits into 8 choghadiyas of 1 h 22 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 08:18, for Krittika.

Add the Sun's and the Moon's places among the stars: 211.8° + 25.2° = 237°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 10:45, then Parigha.

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 06:49, when the lead reaches 174°; Bava until 19:28.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:28 to 05:28 Wed, so the hours after midnight still belong to Mangalawara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 2 Dec, finds it in Vrishchika and begins Margashirsha.

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 3 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1975, 13:38 Fri. Since then the Sun has moved 214.1° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
