Panchang in Ipameri, Goiás, Brazil Thu 14 Nov 1940

Kartik Purnima follows the tithi at sunrise. Purnima runs from 21:18 on Wed 13 Nov to 23:23 on Thu 14 Nov, so it holds sunrise only on Thu 14 Nov, at 05:29. 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, 05:29 here. Chaturdashi ended at 21:18 Wed, before it. Purnima ends at 23:23, when the lead reaches 180°. The lead passed 0° at the new moon of 30 Oct, so the Moon is waxing: Shukla paksha.

The night of Wed 13 Nov ran from sunset 18:24 Wed to sunrise 05:29, 11 h 5 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 18:25, 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, 18:25 to 05:29 Fri, splits into 8 choghadiyas of 1 h 23 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 3 at 20°. It leaves at 17:40, for Krittika.

Add the Sun's and the Moon's places among the stars: 208.8° + 20.5° = 229.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 01:01 Fri, 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 10:23, when the lead reaches 174°; Bava until 23:23.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:29 Fri, so the hours after midnight still belong to Guruwara.

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 15 Nov, inside the month. The next new moon, 29 Nov, 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 30 Oct, 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: 7 Apr 1940, 17:18 Sun. Since then the Sun has moved 214° round the stars. Vikram Samvat numbers that year 1997; Shaka Samvat numbers it 1862.
