Panchang in Sevan, Gegharkunik, Armenia Thu 20 Aug 1987

Smartas test Ekadashi at sunrise. It holds both sunrises, 07:13 on Wed 19 Aug and 07:14 on Thu 20 Aug. Ekadashi (05:18 Wed 19 Aug to 07:34 Thu 20 Aug) and Dwadashi (07:34 Thu 20 Aug to 09:59 Fri 21 Aug) are both longer than their day; when both grow, Smartas take the later day: Thu 20 Aug. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Aja Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 07:14 here. Dashami ended at 05:18 Wed, before it. Ekadashi ends at 07:34, when the lead reaches 312°. The lead passed 180° at the full moon of 9 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:18 Wed, before sunrise at 07:13 Wed, and ends at 07:34, after the next sunrise at 07:14. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Wed 19 Aug ran from sunset 20:53 Wed to sunrise 07:14, 10 h 21 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:14 to 20:51, 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, 20:51 to 07:15 Fri, splits into 8 choghadiyas of 1 h 18 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 3 at 73°20′. It leaves at 17:55, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 122.9° + 74.7° = 197.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 11:45, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava ended at 18:24 Wed, when the lead reached 306°; Balava runs until 07:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:14 to 07:15 Fri, so the hours after midnight still belong to Guruwara.

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 17 Aug, inside the month. The next new moon, 24 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 24 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 29 Mar 1987, 17:45 Sun. Since then the Sun has moved 138.3° round the stars. Vikram Samvat numbers that year 2044; Shaka Samvat numbers it 1909.
