Panchang in Sevan, Gegharkunik, Armenia Wed 17 Aug 2016

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 14:57 on Wed 17 Aug to 13:26 on Thu 18 Aug, so it touches only Wednesday’s aparahna (14:25–17:10). Bhadra lasts until 02:15 Thu, and the Dharmasindhu keeps the rite out of bhadra: it is done from 02:15 Thu.

Raksha Bandhan muhurat: the time after bhadra, at 02:15 Thu.

Raksha Bandhan: every date in Sevan

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, 06:12 here. Trayodashi ended at 15:56 Tue, before it. Chaturdashi ends at 14:57, when the lead reaches 168°. The lead passed 0° at the new moon of 3 Aug, so the Moon is waxing: Shukla paksha.

The night of Tue 16 Aug ran from sunset 19:55 Tue to sunrise 06:12, 10 h 17 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:12 to 19:54, splits into 8 choghadiyas of 1 h 42 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:54 to 06:13 Thu, splits into 8 choghadiyas of 1 h 17 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 22:46, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 120.5° + 283.9° = 404.4°, one full turn and 44.4°. 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 20:50, then Shobhana.

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 03:31, when the lead reached 162°; Vanija runs until 14:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:12 to 06:13 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, 1 Sep, 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 3 Aug, 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: 7 Apr 2016, 15:23 Thu. Since then the Sun has moved 126.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
