Panchang in Diffa, Niger Thu 20 Dec 2029

Purnima follows the tithi at sunrise. Purnima runs from 22:00 on Wed 19 Dec to 23:46 on Thu 20 Dec, so it holds sunrise only on Thu 20 Dec, at 06:26. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Diffa

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, 06:26 here. Chaturdashi ended at 22:00 Wed, before it. Purnima ends at 23:46, 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 Wed 19 Dec ran from sunset 17:47 Wed to sunrise 06:26, 12 h 39 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:26 to 17:47, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:47 to 06:27 Fri, 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 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 02:54 Fri, for Ardra.

Add the Sun's and the Moon's places among the stars: 244.3° + 56.2° = 300.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 17:31, 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 10:56, when the lead reaches 174°; Bava until 23:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:26 to 06:27 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 4 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: 15 Mar 2029, 05:19 Thu. Since then the Sun has moved 273.7° round the stars. Vikram Samvat numbers that year 2086; Shaka Samvat numbers it 1951.
