Panchang in Ipameri, Goiás, Brazil Wed 15 May 1985

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:30 on Tue 14 May and 06:30 on Wed 15 May. Ekadashi (06:23 Tue 14 May to 08:44 Wed 15 May) and Dwadashi (08:44 Wed 15 May to 11:18 Thu 16 May) are both longer than their day; when both grow, Smartas take the later day: Wed 15 May. Vaishnavas test arunodaya: on Tue 14 May Dashami lasts until 06:23, inside it (04:54–06:30); on Wed 15 May Ekadashi holds all of it.

Apara 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, 06:30 here. Dashami ended at 06:23 Tue, before it. Ekadashi ends at 08:44, when the lead reaches 312°. The lead passed 180° at the full moon of 4 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:23 Tue, before sunrise at 06:30 Tue, and ends at 08:44, after the next sunrise at 06:30. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Tue 14 May ran from sunset 17:47 Tue to sunrise 06:30, 12 h 43 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 17:47, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:47 to 06:30 Thu, splits into 8 choghadiyas of 1 h 35 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 3 at 340°. It leaves at 16:19, for Revati.

Add the Sun's and the Moon's places among the stars: 30.8° + 341.8° = 372.6°, one full turn and 12.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 07:44, then Priti.

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 19:31 Tue, when the lead reached 306°; Balava runs until 08:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:30 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 19 May, finds it in Vrishabha and begins Jyeshtha.

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 19 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1985, 08:58 Thu. Since then the Sun has moved 53.6° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
