Panchang in Davinópolis, Maranhão, Brazil Sun 31 Oct 2021

Smartas test Ekadashi at sunrise. It begins at 05:57 on Sun 31 Oct, after that sunrise (05:44), and ends at 04:52 on Mon 1 Nov, before the next (05:43 Mon): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Sun 31 Oct.

Rama Ekadashi: every date in Davinópolis

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 06:13 Sat, before it. Dashami ends at 05:57, when the lead reaches 300°. The lead passed 180° at the full moon of 20 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:57 and ended at 04:52 Mon, between the sunrises of 05:44 and 05:43 Mon. Sunday reads Dashami and Monday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Sat 30 Oct ran from sunset 18:02 Sat to sunrise 05:44, 11 h 42 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:44 to 18:02, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 05:43 Mon, splits into 8 choghadiyas of 1 h 27 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 1 at 133°20′. It leaves at 04:22 Mon, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 194° + 133.9° = 327.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 14:50, then Indra.

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 18:12 Sat, when the lead reached 294°; Vishti runs until 05:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:44 to 05:43 Mon, so the hours after midnight still belong to Raviwara.

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, 4 Nov, 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 4 Nov, 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: 11 Apr 2021, 23:30 Sun. Since then the Sun has moved 195.7° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
