Panchang in Khmelnytskyi, Ukraine Tue 20 Aug 2013

The rakhi is tied in aparahna, the fourth fifth of the day, outside bhadra. Purnima runs from 07:51 on Tue 20 Aug to 04:44 on Wed 21 Aug, so only Tuesday’s aparahna (14:39–17:29) falls within it. Bhadra lasts until 18:16, and the Dharmasindhu keeps the rite out of bhadra: it is done from 18:16. Every reading takes that day.

Raksha Bandhan muhurat: the time after bhadra, at 18:16.

Raksha Bandhan: every date in Khmelnytskyi

Purnima follows the tithi at sunrise. Purnima begins at 07:51 on Tue 20 Aug, after that sunrise, and ends at 04:44 on Wed 21 Aug, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Tue 20 Aug. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Khmelnytskyi

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, 06:10 here. Trayodashi ended at 11:09 Mon, before it. Chaturdashi ends at 07:51, when the lead reaches 168°. The lead passed 0° at the new moon of 7 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 07:51 and ended at 04:44 Wed, between the sunrises of 06:10 and 06:11 Wed. Tuesday reads Chaturdashi and Wednesday reads Pratipada: Purnima is a kshaya tithi here.

The night of Mon 19 Aug ran from sunset 20:21 Mon to sunrise 06:10, 9 h 49 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 20:19, splits into 8 choghadiyas of 1 h 46 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:19 to 06:11 Wed, splits into 8 choghadiyas of 1 h 14 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 4 at 290°. It leaves at 11:09, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 123.2° + 290.3° = 413.5°, one full turn and 53.5°. 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 02:17 Wed, 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 21:30 Mon, when the lead reached 162°; Vanija runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:11 Wed, so the hours after midnight still belong to Mangalawara.

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, 5 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 7 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: 10 Apr 2013, 12:35 Wed. Since then the Sun has moved 126.6° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
