Panchang in Ipameri, Goiás, Brazil Fri 30 Oct 2020

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 09:16 on Fri 30 Oct to 11:49 on Sat 31 Oct, so only Friday night’s nishitha (23:33–00:18 Sat) 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, 05:34 here. Trayodashi ended at 06:46 Thu, before it. Chaturdashi ends at 09:16, when the lead reaches 168°. The lead passed 0° at the new moon of 16 Oct, so the Moon is waxing: Shukla paksha.

The night of Thu 29 Oct ran from sunset 18:18 Thu to sunrise 05:34, 11 h 16 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:34 to 18:18, 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, 18:18 to 05:34 Sat, 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 06:27, for Ashwini.

Add the Sun's and the Moon's places among the stars: 193.2° + 359.6° = 552.8°, one full turn and 192.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 19:01, 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 20:00 Thu, when the lead reached 162°; Vanija runs until 09:16.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:34 to 05:34 Sat, so the hours after midnight still belong to Shukrawara.

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, 15 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 16 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: 24 Mar 2020, 06:28 Tue. Since then the Sun has moved 213.1° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
