Panchang in Sevan, Gegharkunik, Armenia Sat 24 Nov 2012

Smartas test Ekadashi at sunrise. It holds both sunrises, 07:55 on Fri 23 Nov and 07:56 on Sat 24 Nov. Ekadashi (07:36 Fri 23 Nov to 09:08 Sat 24 Nov) and Dwadashi (09:08 Sat 24 Nov to 11:08 Sun 25 Nov) are both longer than their day; when both grow, Smartas take the later day: Sat 24 Nov. Vaishnavas test arunodaya: on Fri 23 Nov Dashami lasts until 07:36, inside it (06:19–07:55); on Sat 24 Nov Ekadashi holds all of it.

Dev Uthani 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, 07:56 here. Dashami ended at 07:36 Fri, before it. Ekadashi ends at 09:08, when the lead reaches 132°. The lead passed 0° at the new moon of 14 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:36 Fri, before sunrise at 07:55 Fri, and ends at 09:08, after the next sunrise at 07:56. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 23 Nov ran from sunset 17:37 Fri to sunrise 07:56, 14 h 19 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:56 to 17:36, splits into 8 choghadiyas of 1 h 12 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:36 to 07:57 Sun, splits into 8 choghadiyas of 1 h 47 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 1 at 346°40′. It leaves at 04:23 Sun, for Ashwini.

Add the Sun's and the Moon's places among the stars: 218.2° + 349.7° = 567.9°, one full turn and 207.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 17:49, then Vyatipata.

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 ended at 20:18 Fri, when the lead reached 126°; Vishti runs until 09:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:56 to 07:57 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 13 Dec, finds it in Vrishchika and begins Margashirsha.

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 14 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 18:37 Thu. Since then the Sun has moved 239.9° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
