Panchang in Davinópolis, Maranhão, Brazil Mon 8 Apr 2002

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:11 on Sun 7 Apr and 06:10 on Mon 8 Apr. Ekadashi (04:24 Sun 7 Apr to 06:43 Mon 8 Apr) and Dwadashi (06:43 Mon 8 Apr to 09:11 Tue 9 Apr) are both longer than their day; when both grow, Smartas take the later day: Mon 8 Apr. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Papamochani Ekadashi: every date in Davinópolis

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, 06:10 here. Dashami ended at 04:24 Sun, before it. Ekadashi ends at 06:43, when the lead reaches 312°. The lead passed 180° at the full moon of 28 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:24 Sun, before sunrise at 06:11 Sun, and ends at 06:43, after the next sunrise at 06:10. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Sun 7 Apr ran from sunset 18:12 Sun to sunrise 06:10, 11 h 58 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 18:11, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:11 to 06:10 Tue, splits into 8 choghadiyas of 1 h 29 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 4 at 303°20′. It leaves at 07:04, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 354.5° + 306.2° = 660.7°, one full turn and 300.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 17:19, then Shukla.

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 17:32 Sun, when the lead reached 306°; Balava runs until 06:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:10 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 12 Apr, finds it in Meena and begins Chaitra.

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 12 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2001, 22:21 Sat. Since then the Sun has moved 373.9° round the stars. Vikram Samvat numbers that year 2058; Shaka Samvat numbers it 1923.
