Panchang in Davinópolis, Maranhão, Brazil Thu 12 Nov 2009

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 12 Nov only, at 05:43: Thu 12 Nov. Vaishnavas test arunodaya: Dashami ended at 20:28 Wed, before it (04:07–05:43).

Utpanna Ekadashi: every date in Davinópolis

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 05:43 here. Dashami ended at 20:28 Wed, before it. Ekadashi ends at 19:00, when the lead reaches 312°. The lead passed 180° at the full moon of 2 Nov, so the Moon is waning: Krishna paksha.

The night of Wed 11 Nov ran from sunset 18:04 Wed to sunrise 05:43, 11 h 39 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:43 to 18:04, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:04 to 05:43 Fri, splits into 8 choghadiyas of 1 h 27 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 21:21, for Hasta.

Add the Sun's and the Moon's places among the stars: 206.1° + 151° = 357.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 10:22, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava runs until 07:43, when the lead reaches 306°; Balava until 19:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:43 to 05:43 Fri, so the hours after midnight still belong to Guruwara.

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, 16 Nov, 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 16 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 2009, 13:05 Thu. Since then the Sun has moved 224° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
