Panchang in Diffa, Niger Fri 13 Sep 2019

Purnima follows the tithi at sunrise. Purnima runs from 03:05 on Fri 13 Sep to 05:32 on Sat 14 Sep, so it holds sunrise only on Fri 13 Sep, at 05:58. 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, 05:58 here. Chaturdashi ended at 03:05, before it. Purnima ends at 05:32 Sat, when the lead reaches 180°. The lead passed 0° at the new moon of 30 Aug, so the Moon is waxing: Shukla paksha.

The night of Thu 12 Sep ran from sunset 18:13 Thu to sunrise 05:58, 11 h 45 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:58 to 18:12, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:12 to 05:58 Sat, splits into 8 choghadiyas of 1 h 28 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 3 at 313°20′. It leaves at 15:28, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 146° + 315.3° = 461.3°, one full turn and 101.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 16:00, then Shula.

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 16:19, when the lead reaches 174°; Bava until 05:32 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:58 to 05:58 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 28 Sep, finds it in Kanya and begins Ashwina.

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 30 Aug, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 2019, 09:50 Fri. Since then the Sun has moved 154.8° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
