Panchang in Sevan, Gegharkunik, Armenia Mon 13 Aug 1951

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 13 Aug only, at 05:07: Mon 13 Aug. Vaishnavas test arunodaya: Dashami ended at 21:39 Sun, before it (03:31–05:07).

Shravana Putrada 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, 05:07 here. Dashami ended at 21:39 Sun, before it. Ekadashi ends at 18:41, when the lead reaches 132°. The lead passed 0° at the new moon of 3 Aug, so the Moon is waxing: Shukla paksha.

The night of Sun 12 Aug ran from sunset 19:02 Sun to sunrise 05:07, 10 h 5 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:07 to 19:01, splits into 8 choghadiyas of 1 h 44 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:01 to 05:08 Tue, splits into 8 choghadiyas of 1 h 15 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 01:54 Tue, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 116.4° + 240.6° = 357°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 09:49, then Vishkambha.

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 08:12, when the lead reaches 126°; Vishti until 18:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:07 to 05:08 Tue, so the hours after midnight still belong to Somawara.

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, 1 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 3 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 1951, 13:51 Fri. Since then the Sun has moved 123.7° round the stars. Vikram Samvat numbers that year 2008; Shaka Samvat numbers it 1873.
