Panchang in Ipameri, Goiás, Brazil Fri 16 Apr 1943

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:21 on Thu 15 Apr and 06:21 on Fri 16 Apr. Ekadashi (06:07 Thu 15 Apr to 07:51 Fri 16 Apr) and Dwadashi (07:51 Fri 16 Apr to 08:57 Sat 17 Apr) are both longer than their day; when both grow, Smartas take the later day: Fri 16 Apr. Vaishnavas test arunodaya: on Thu 15 Apr Dashami lasts until 06:07, inside it (04:45–06:21); on Fri 16 Apr Ekadashi holds all of it.

Kamada 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, 06:21 here. Dashami ended at 06:07 Thu, before it. Ekadashi ends at 07:51, when the lead reaches 132°. The lead passed 0° at the new moon of 4 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:07 Thu, before sunrise at 06:21 Thu, and ends at 07:51, after the next sunrise at 06:21. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 15 Apr ran from sunset 18:03 Thu to sunrise 06:21, 12 h 18 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:21 to 18:03, 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 night here, 18:03 to 06:22 Sat, 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 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 07:18 Sat, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 2.5° + 133.7° = 136.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 01:08 Sat, then Dhruva.

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 19:04 Thu, when the lead reached 126°; Vishti runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 to 06:22 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 4 May, finds it in Mesha and begins Vaishakha.

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 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 1943, 18:52 Sun. Since then the Sun has moved 11.3° round the stars. Vikram Samvat numbers that year 2000; Shaka Samvat numbers it 1865.
