Panchang in Diffa, Niger Thu 12 Jun 2014

Purnima follows the tithi at sunrise. Purnima begins at 07:57 on Thu 12 Jun, after that sunrise, and ends at 05:11 on Fri 13 Jun, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 12 Jun. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:42 here. Trayodashi ended at 10:13 Wed, before it. Chaturdashi ends at 07:57, when the lead reaches 168°. The lead passed 0° at the new moon of 28 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 07:57 and ended at 05:11 Fri, between the sunrises of 05:42 and 05:42 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Purnima is a kshaya tithi here.

The night of Wed 11 Jun ran from sunset 18:36 Wed to sunrise 05:42, 11 h 6 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:36, splits into 8 choghadiyas of 1 h 36 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:36 to 05:42 Fri, splits into 8 choghadiyas of 1 h 23 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 4 at 223°20′. It leaves at 10:25, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 57.1° + 223.8° = 280.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 00:58 Fri, then Shubha.

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 21:09 Wed, when the lead reached 162°; Vanija runs until 07:57.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 27 Jun, finds it in Mithuna and begins Ashadha.

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 28 May, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 2014, 19:44 Sun. Since then the Sun has moved 71.2° round the stars. Vikram Samvat numbers that year 2071; Shaka Samvat numbers it 1936.
