Panchang in Ipameri, Goiás, Brazil Mon 22 Oct 2007

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 22 Oct only, at 06:39: Mon 22 Oct. Vaishnavas test arunodaya: Dashami ended at 17:35 Sun, before it (05:03–06:39).

Papankusha Ekadashi: every date in Ipameri

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 17:35 Sun, before it. Ekadashi ends at 15:49, when the lead reaches 132°. The lead passed 0° at the new moon of 11 Oct, so the Moon is waxing: Shukla paksha.

The night of Sun 21 Oct ran from sunset 19:14 Sun to sunrise 06:39, 11 h 25 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 19:15, 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, 19:15 to 06:38 Tue, splits into 8 choghadiyas of 1 h 25 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 2 at 310°. It leaves at 20:55, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 184.6° + 311.6° = 496.2°, one full turn and 136.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 23:14, then Dhruva.

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 04:48, when the lead reached 126°; Vishti runs until 15:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:38 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 9 Nov, finds it in Tula and begins Kartika.

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 11 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 2007, 23:42 Sun. Since then the Sun has moved 210.4° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
