Panchang in Sevan, Gegharkunik, Armenia Mon 31 Aug 2009

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 31 Aug only, at 07:26: Mon 31 Aug. Vaishnavas test arunodaya: Dashami ended at 09:51 Sun, before it (05:50–07:26).

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, 07:26 here. Dashami ended at 09:51 Sun, before it. Ekadashi ends at 12:26, when the lead reaches 132°. The lead passed 0° at the new moon of 20 Aug, so the Moon is waxing: Shukla paksha.

The night of Sun 30 Aug ran from sunset 20:35 Sun to sunrise 07:26, 10 h 51 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:26 to 20:33, 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, 20:33 to 07:27 Tue, splits into 8 choghadiyas of 1 h 21 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 4 at 263°20′. It leaves at 13:43, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 133.8° + 263.6° = 397.4°, one full turn and 37.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 12:17, then Saubhagya.

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 23:08 Sun, when the lead reached 126°; Vishti runs until 12:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:26 to 07:27 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 18 Sep, 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 20 Aug, 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: 26 Mar 2009, 20:05 Thu. Since then the Sun has moved 151.7° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
