Panchang in Ipameri, Goiás, Brazil Thu 16 Oct 2081

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 15:45 on Thu 16 Oct to 17:51 on Fri 17 Oct, so only Thursday night’s nishitha (23:35–00:20 Fri) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad 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, 05:42 here. Trayodashi ended at 13:20 Wed, before it. Chaturdashi ends at 15:45, when the lead reaches 168°. The lead passed 0° at the new moon of 2 Oct, so the Moon is waxing: Shukla paksha.

The night of Wed 15 Oct ran from sunset 18:13 Wed to sunrise 05:42, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:13, 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 night here, 18:13 to 05:42 Fri, 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 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 3 at 340°. It leaves at 14:54, for Revati.

Add the Sun's and the Moon's places among the stars: 178.7° + 342.1° = 520.8°, one full turn and 160.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 04:59 Fri, then Harshana.

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 02:35, when the lead reached 162°; Vanija runs until 15:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:42 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 17 Oct, inside the month. The next new moon, 1 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 2 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: 9 Apr 2081, 05:16 Wed. Since then the Sun has moved 183.5° round the stars. Vikram Samvat numbers that year 2138; Shaka Samvat numbers it 2003.
