Panchang in Ipameri, Goiás, Brazil Mon 10 Dec 2096

Smartas test Ekadashi at sunrise. It holds both sunrises, 05:30 on Sun 9 Dec and 05:30 on Mon 10 Dec. Ekadashi (04:10 Sun 9 Dec to 06:25 Mon 10 Dec) and Dwadashi (06:25 Mon 10 Dec to 09:00 Tue 11 Dec) are both longer than their day; when both grow, Smartas take the later day: Mon 10 Dec. Vaishnavas test arunodaya: on Sun 9 Dec Dashami lasts until 04:10, inside it (03:54–05:30); on Mon 10 Dec Ekadashi holds all of it.

Utpanna 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, 05:30 here. Dashami ended at 04:10 Sun, before it. Ekadashi ends at 06:25, when the lead reaches 312°. The lead passed 180° at the full moon of 29 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:10 Sun, before sunrise at 05:30 Sun, and ends at 06:25, after the next sunrise at 05:30. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Sun 9 Dec ran from sunset 18:40 Sun to sunrise 05:30, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:30 to 18:41, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:41 to 05:31 Tue, splits into 8 choghadiyas of 1 h 21 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 07:29, for Swati.

Add the Sun's and the Moon's places among the stars: 234.1° + 185.7° = 419.8°, one full turn and 59.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 18:19, then Atiganda.

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 17:14 Sun, when the lead reached 306°; Balava runs until 06:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:30 to 05:31 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 14 Dec, 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 14 Dec, 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: 24 Mar 2096, 05:56 Sat. Since then the Sun has moved 254.5° round the stars. Vikram Samvat numbers that year 2153; Shaka Samvat numbers it 2018.
