Panchang in Sevan, Gegharkunik, Armenia Sun 1 Sep 2013

Smartas test Ekadashi at sunrise: it holds sunrise on Sun 1 Sep only, at 06:27: Sun 1 Sep. Vaishnavas test arunodaya: Dashami ended at 07:34 Sat, before it (04:51–06:27).

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, 06:27 here. Dashami ended at 07:34 Sat, before it. Ekadashi ends at 09:56, when the lead reaches 312°. The lead passed 180° at the full moon of 21 Aug, so the Moon is waning: Krishna paksha.

The night of Sat 31 Aug ran from sunset 19:33 Sat to sunrise 06:27, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:27 to 19:32, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:32 to 06:28 Mon, splits into 8 choghadiyas of 1 h 22 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 2 at 83°20′. It leaves at 22:47, for Pushya.

Add the Sun's and the Moon's places among the stars: 134.8° + 85.2° = 220°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 18:54, then Variyana.

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 20:46 Sat, when the lead reached 306°; Balava runs until 09:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:27 to 06:28 Mon, so the hours after midnight still belong to Raviwara.

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 5 Sep, 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: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 138.2° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
