Panchang in Sevan, Gegharkunik, Armenia Sat 13 Sep 2081

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 13 Sep only, at 06:39: Sat 13 Sep. Vaishnavas test arunodaya: Dashami ended at 20:09 Fri, before it (05:03–06:39).

Parsva Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 06:39 here. Dashami ended at 20:09 Fri, before it. Ekadashi ends at 21:55, when the lead reaches 132°. The lead passed 0° at the new moon of 3 Sep, so the Moon is waxing: Shukla paksha.

The night of Fri 12 Sep ran from sunset 19:13 Fri to sunrise 06:39, 11 h 26 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 19:11, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:11 to 06:40 Sun, splits into 8 choghadiyas of 1 h 26 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 2 at 270°. It leaves at 00:38 Sun, for Shravana.

Add the Sun's and the Moon's places among the stars: 146° + 270.9° = 416.9°, one full turn and 56.9°. 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 00:29 Sun, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija runs until 08:59, when the lead reaches 126°; Vishti until 21:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:40 Sun, so the hours after midnight still belong to Shaniwara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 2 Oct, finds it in Kanya and begins Ashwina.

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 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2081, 12:16 Wed. Since then the Sun has moved 150.8° round the stars. Vikram Samvat numbers that year 2138; Shaka Samvat numbers it 2003.
