Panchang in Ipameri, Goiás, Brazil Wed 12 Aug 1992

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 05:00 on Wed 12 Aug to 07:27 on Thu 13 Aug, so only Wednesday’s aparahna (13:26–15:44) falls within it. Bhadra lasts until 18:13, and the Dharmasindhu keeps the rite out of bhadra: it is done from 18:13. Every reading takes that day.

Raksha Bandhan muhurat: the time after bhadra, at 18:13.

Purnima follows the tithi at sunrise. Purnima holds both sunrises, 06:33 on Wed 12 Aug and 06:32 on Thu 13 Aug. Over two sunrises the Nirnayasindhu takes the first: Wed 12 Aug. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

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, 06:33 here. Chaturdashi ended at 05:00, before it. Purnima ends at 07:27 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 29 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 05:00, before sunrise at 06:33, and ends at 07:27 Thu, after the next sunrise at 06:32 Thu. Both days read Purnima: it is a vriddhi tithi here.

The night of Tue 11 Aug ran from sunset 18:01 Tue to sunrise 06:33, 12 h 32 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:33 to 18:02, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 06:32 Thu, splits into 8 choghadiyas of 1 h 33 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 2 at 283°20′. It leaves at 23:42, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 116.2° + 284.9° = 401.1°, one full turn and 41.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 05:37 Thu, then Shobhana.

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 18:13, when the lead reaches 174°; Bava until 07:27 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:33 to 06:32 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, 27 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 29 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: 3 Apr 1992, 02:01 Fri. Since then the Sun has moved 126.3° round the stars. Vikram Samvat numbers that year 2049; Shaka Samvat numbers it 1914.
