Panchang in Ipameri, Goiás, Brazil Sat 19 Dec 2048

Purnima follows the tithi at sunrise. Purnima runs from 01:00 on Sat 19 Dec to 03:39 on Sun 20 Dec, so it holds sunrise only on Sat 19 Dec, at 05:34. 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: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 05:34 here. Chaturdashi ended at 01:00, before it. Purnima ends at 03:39 Sun, when the lead reaches 180°. The lead passed 0° at the new moon of 5 Dec, so the Moon is waxing: Shukla paksha.

The night of Fri 18 Dec ran from sunset 18:45 Fri to sunrise 05:34, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:34 to 18:46, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:46 to 05:34 Sun, splits into 8 choghadiyas of 1 h 21 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 08:03 Sun, for Ardra.

Add the Sun's and the Moon's places among the stars: 243.6° + 53.6° = 297.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 23:16, then Shukla.

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 14:18, when the lead reaches 174°; Bava until 03:39 Sun.

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

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 3 Jan, finds it in Dhanu and begins Pausha.

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 5 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 2048, 11:27 Sat. Since then the Sun has moved 273.4° round the stars. Vikram Samvat numbers that year 2105; Shaka Samvat numbers it 1970.
