Panchang in Ipameri, Goiás, Brazil Mon 23 Jan 2017

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 23 Jan only, at 06:55: Mon 23 Jan. Vaishnavas test arunodaya: Dashami ended at 14:29 Sun, before it (05:19–06:55).

Shattila Ekadashi: every date in Ipameri

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, 06:55 here. Dashami ended at 14:29 Sun, before it. Ekadashi ends at 16:51, when the lead reaches 312°. The lead passed 180° at the full moon of 12 Jan, so the Moon is waning: Krishna paksha.

The night of Sun 22 Jan ran from sunset 19:54 Sun to sunrise 06:55, 11 h 1 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:55 to 19:54, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:54 to 06:55 Tue, splits into 8 choghadiyas of 1 h 22 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 1 at 226°40′. It leaves at 09:03 Tue, for Mula.

Add the Sun's and the Moon's places among the stars: 279.4° + 226.9° = 506.3°, one full turn and 146.3°. 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 07:29, then Dhruva.

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 ended at 03:42, when the lead reached 306°; Balava runs until 16:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:55 to 06:55 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 27 Jan, 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 27 Jan, 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: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 285.4° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
