Panchang in Sevan, Gegharkunik, Armenia Fri 19 Jul 2013

Smartas test Ekadashi at sunrise: it holds sunrise on Fri 19 Jul only, at 05:45: Fri 19 Jul. Vaishnavas test arunodaya: Dashami ended at 15:12 Thu, before it (04:09–05:45).

Devshayani 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, 05:45 here. Dashami ended at 15:12 Thu, before it. Ekadashi ends at 12:30, when the lead reaches 132°. The lead passed 0° at the new moon of 8 Jul, so the Moon is waxing: Shukla paksha.

The night of Thu 18 Jul ran from sunset 20:27 Thu to sunrise 05:45, 9 h 18 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:45 to 20:26, splits into 8 choghadiyas of 1 h 50 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:26 to 05:46 Sat, splits into 8 choghadiyas of 1 h 10 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 15:34, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 92.5° + 220.7° = 313.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 16:12, then Brahma.

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 01:55, when the lead reached 126°; Vishti runs until 12:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:45 to 05:46 Sat, so the hours after midnight still belong to Shukrawara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 7 Aug, finds it in Karka and begins Shravana.

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 8 Jul, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

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 95.9° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
