Panchang in Ipameri, Goiás, Brazil Wed 5 Sep 2018

Smartas test Ekadashi at sunrise. It begins at 06:30 on Wed 5 Sep, after that sunrise (06:16), and ends at 03:45 on Thu 6 Sep, before the next (06:15 Thu): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Wed 5 Sep.

Aja 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, 06:16 here. Navami ended at 08:53 Tue, before it. Dashami ends at 06:30, when the lead reaches 300°. The lead passed 180° at the full moon of 26 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:30 and ended at 03:45 Thu, between the sunrises of 06:16 and 06:15 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 4 Sep ran from sunset 18:06 Tue to sunrise 06:16, 12 h 10 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:06, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:06 to 06:15 Thu, splits into 8 choghadiyas of 1 h 31 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 08:44, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 138.7° + 78.5° = 217.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 21:00, then Variyana.

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 ended at 19:45 Tue, when the lead reached 294°; Vishti runs until 06:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:15 Thu, so the hours after midnight still belong to Budhawara.

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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 9 Sep, finds it in Simha and begins Bhadrapada.

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 9 Sep, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 10:11 Sat. Since then the Sun has moved 165.9° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
