Panchang in Ipameri, Goiás, Brazil Mon 19 Nov 2018

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:28 on Sun 18 Nov and 06:28 on Mon 19 Nov. Ekadashi (06:03 Sun 18 Nov to 07:00 Mon 19 Nov) and Dwadashi (07:00 Mon 19 Nov to 07:10 Tue 20 Nov) are both longer than their day; when both grow, Smartas take the later day: Mon 19 Nov. Vaishnavas test arunodaya: on Sun 18 Nov Dashami lasts until 06:03, inside it (04:52–06:28); on Mon 19 Nov Ekadashi holds all of it.

Dev Uthani Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 06:28 here. Dashami ended at 06:03 Sun, before it. Ekadashi ends at 07:00, when the lead reaches 132°. The lead passed 0° at the new moon of 7 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:03 Sun, before sunrise at 06:28 Sun, and ends at 07:00, after the next sunrise at 06:28. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Sun 18 Nov ran from sunset 19:27 Sun to sunrise 06:28, 11 h 1 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:28 to 19:28, 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, 19:28 to 06:28 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 10:24, for Revati.

Add the Sun's and the Moon's places among the stars: 212.8° + 344.6° = 557.4°, one full turn and 197.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 10:59, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 18:37 Sun, when the lead reached 126°; Vishti runs until 07:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:28 to 06:28 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, 7 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 7 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

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 240° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
