Panchang in Davinópolis, Maranhão, Brazil Sat 2 Feb 2008

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 2 Feb only, at 06:13: Sat 2 Feb. Vaishnavas test arunodaya: Dashami ended at 20:11 Fri, before it (04:37–06:13).

Shattila 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, 06:13 here. Dashami ended at 20:11 Fri, before it. Ekadashi ends at 22:10, when the lead reaches 312°. The lead passed 180° at the full moon of 22 Jan, so the Moon is waning: Krishna paksha.

The night of Fri 1 Feb ran from sunset 18:33 Fri to sunrise 06:13, 11 h 40 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:13 to 18:33, 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, 18:33 to 06:13 Sun, 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 3 at 233°20′. It leaves at 19:01, for Mula.

Add the Sun's and the Moon's places among the stars: 288.9° + 233.5° = 522.4°, one full turn and 162.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 02:03 Sun, then Harshana.

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 09:14, when the lead reaches 306°; Balava until 22:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:13 to 06:13 Sun, so the hours after midnight still belong to Shaniwara.

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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 7 Feb, finds it in Makara and begins Magha.

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 7 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

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 314.7° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
