Panchang in Ipameri, Goiás, Brazil Fri 9 Mar 1979

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:13 on Thu 8 Mar and 06:14 on Fri 9 Mar. Ekadashi (05:52 Thu 8 Mar to 08:23 Fri 9 Mar) and Dwadashi (08:23 Fri 9 Mar to 11:02 Sat 10 Mar) are both longer than their day; when both grow, Smartas take the later day: Fri 9 Mar. Vaishnavas test arunodaya: on Thu 8 Mar Dashami lasts until 05:52, inside it (04:37–06:13); on Fri 9 Mar Ekadashi holds all of it.

Amalaki 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, 06:14 here. Dashami ended at 05:52 Thu, before it. Ekadashi ends at 08:23, when the lead reaches 132°. The lead passed 0° at the new moon of 26 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:52 Thu, before sunrise at 06:13 Thu, and ends at 08:23, after the next sunrise at 06:14. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 8 Mar ran from sunset 18:33 Thu to sunrise 06:14, 11 h 41 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 06:14 Sat, 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 04:35 Sat, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 324.6° + 95.7° = 420.3°, one full turn and 60.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 18:08, then Atiganda.

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 19:06 Thu, when the lead reached 126°; Vishti runs until 08:23.

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

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, 27 Mar, 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 26 Feb, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1978, 12:15 Fri. Since then the Sun has moved 330.7° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
