Panchang in Diffa, Niger Wed 6 Aug 2036

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 01:14 on Wed 6 Aug to 03:48 on Thu 7 Aug, so only Wednesday’s aparahna (13:31–16:03) falls within it. Bhadra lasts until 14:31, and the Dharmasindhu keeps the rite out of bhadra: it is done from 14:31. Every reading takes that day.

Raksha Bandhan muhurat: the time after bhadra, 14:31–16:03.

Raksha Bandhan: every date in Diffa

Purnima follows the tithi at sunrise. Purnima runs from 01:14 on Wed 6 Aug to 03:48 on Thu 7 Aug, so it holds sunrise only on Wed 6 Aug, at 05:55. 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, 05:55 here. Chaturdashi ended at 01:14, before it. Purnima ends at 03:48 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 23 Jul, so the Moon is waxing: Shukla paksha.

The night of Tue 5 Aug ran from sunset 18:35 Tue to sunrise 05:55, 11 h 20 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:55 to 18:34, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:34 to 05:56 Thu, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shravana spans 280°00′–293°20′; the Moon entered its pada 1 at 280°. It leaves at 08:54 Thu, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 110° + 280.1° = 390.1°, one full turn and 30.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 00:40 Thu, then Saubhagya.

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 14:31, when the lead reaches 174°; Bava until 03:48 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:55 to 05:56 Thu, so the hours after midnight still belong to Budhawara.

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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 21 Aug, finds it in Simha and begins Bhadrapada.

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 23 Jul, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 2036, 21:56 Thu. Since then the Sun has moved 126.6° round the stars. Vikram Samvat numbers that year 2093; Shaka Samvat numbers it 1958.
