Panchang in Ipameri, Goiás, Brazil Thu 29 Oct 1936

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 06:51 on Thu 29 Oct to 02:57 on Fri 30 Oct, so only Thursday night’s nishitha (23:33–00:19 Fri) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Ipameri

Purnima follows the tithi at sunrise. Purnima begins at 06:51 on Thu 29 Oct, after that sunrise, and ends at 02:57 on Fri 30 Oct, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 29 Oct. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:35 here. Trayodashi ended at 10:38 Wed, before it. Chaturdashi ends at 06:51, when the lead reaches 168°. The lead passed 0° at the new moon of 15 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 06:51 and ended at 02:57 Fri, between the sunrises of 05:35 and 05:34 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Purnima is a kshaya tithi here.

The night of Wed 28 Oct ran from sunset 18:17 Wed to sunrise 05:35, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 18:17, 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, 18:17 to 05:34 Fri, 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 02:26 Fri, for Bharani.

Add the Sun's and the Moon's places among the stars: 192.8° + 0° = 192.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 16:12, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 20:46 Wed, when the lead reached 162°; Vanija runs until 06:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:34 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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 14 Nov, finds it in Tula and begins Kartika.

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 15 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1936, 01:13 Mon. Since then the Sun has moved 213.4° round the stars. Vikram Samvat numbers that year 1993; Shaka Samvat numbers it 1858.
