Panchang in Sevan, Gegharkunik, Armenia Fri 25 Aug 1961

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 10:59 on Fri 25 Aug to 07:13 on Sat 26 Aug, so only Friday’s aparahna (14:22–17:02) falls within it. Bhadra lasts until 21:06, and the Dharmasindhu keeps the rite out of bhadra: it is done from 21:06. Every reading takes that day.

Raksha Bandhan muhurat: the time after bhadra, at 21:06.

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, 06:19 here. Trayodashi ended at 14:38 Thu, before it. Chaturdashi ends at 10:59, when the lead reaches 168°. The lead passed 0° at the new moon of 11 Aug, so the Moon is waxing: Shukla paksha.

The night of Thu 24 Aug ran from sunset 19:45 Thu to sunrise 06:19, 10 h 34 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 19:43, splits into 8 choghadiyas of 1 h 40 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:43 to 06:20 Sat, splits into 8 choghadiyas of 1 h 19 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 1 at 293°20′. It leaves at 03:00 Sat, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 128.3° + 293.6° = 421.9°, one full turn and 61.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 13:24, then Atiganda.

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 00:50, when the lead reached 162°; Vanija runs until 10:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:20 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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 10 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 11 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: 16 Mar 1961, 22:50 Thu. Since then the Sun has moved 155.7° round the stars. Vikram Samvat numbers that year 2018; Shaka Samvat numbers it 1883.
