Panchang in Ipameri, Goiás, Brazil Sat 14 Oct 2017

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 14 Oct only, at 06:43: Sat 14 Oct. Vaishnavas test arunodaya: Dashami ended at 17:33, before it (05:07–06:43).

Rama Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:44 here. Navami ended at 18:51 Fri, before it. Dashami ends at 17:33, when the lead reaches 300°. The lead passed 180° at the full moon of 5 Oct, so the Moon is waning: Krishna paksha.

The night of Fri 13 Oct ran from sunset 18:12 Fri to sunrise 05:44, 11 h 32 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:44 to 18:13, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:13 to 06:43 Sun, splits into 8 choghadiyas of 1 h 26 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 2 at 110°. It leaves at 21:50, for Magha.

Add the Sun's and the Moon's places among the stars: 177.1° + 110.9° = 288°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 14:33, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 06:10, when the lead reaches 294°; Vishti until 17:33.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:44 to 06:43 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 19 Oct, 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 19 Oct, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 2017, 23:57 Mon. Since then the Sun has moved 193.6° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
