Panchang in Davinópolis, Maranhão, Brazil Sat 11 Feb 1995

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:14 on Fri 10 Feb and 06:14 on Sat 11 Feb. Ekadashi (04:27 Fri 10 Feb to 06:35 Sat 11 Feb) and Dwadashi (06:35 Sat 11 Feb to 08:09 Sun 12 Feb) are both longer than their day; when both grow, Smartas take the later day: Sat 11 Feb. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Jaya Ekadashi: every date in Davinópolis

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, 06:14 here. Dashami ended at 04:27 Fri, before it. Ekadashi ends at 06:35, when the lead reaches 132°. The lead passed 0° at the new moon of 30 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:27 Fri, before sunrise at 06:14 Fri, and ends at 06:35, after the next sunrise at 06:14. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 10 Feb ran from sunset 18:32 Fri to sunrise 06:14, 11 h 42 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:14 to 18:32, 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, 18:32 to 06:15 Sun, 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 2 at 70°. It leaves at 01:25 Sun, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 298.4° + 70.2° = 368.6°, one full turn and 8.6°. 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 14:50, then Priti.

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 17:35 Fri, when the lead reached 126°; Vishti runs until 06:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:14 to 06:15 Sun, so the hours after midnight still belong to Shaniwara.

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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 1 Mar, finds it in Kumbha and begins Phalguna.

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 30 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 1994, 21:17 Sun. Since then the Sun has moved 301.3° round the stars. Vikram Samvat numbers that year 2051; Shaka Samvat numbers it 1916.
