Panchang in Ipameri, Goiás, Brazil Tue 18 Apr 1944

Smartas test Ekadashi at sunrise. It begins at 08:39 on Tue 18 Apr, after that sunrise (06:22), and ends at 05:53 on Wed 19 Apr, before the next (06:22 Wed): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Tue 18 Apr.

Varuthini Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:22 here. Navami ended at 11:05 Mon, before it. Dashami ends at 08:39, when the lead reaches 300°. The lead passed 180° at the full moon of 8 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 08:39 and ended at 05:53 Wed, between the sunrises of 06:22 and 06:22 Wed. Tuesday reads Dashami and Wednesday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Mon 17 Apr ran from sunset 18:02 Mon to sunrise 06:22, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 18:01, 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, 18:01 to 06:22 Wed, 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 4 at 303°20′. It leaves at 11:02, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 5.1° + 303.9° = 309°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 23:25, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 21:55 Mon, when the lead reached 294°; Vishti runs until 08:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:22 Wed, so the hours after midnight still belong to Mangalawara.

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, 22 Apr, 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 22 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1944, 08:36 Fri. Since then the Sun has moved 24.5° round the stars. Vikram Samvat numbers that year 2001; Shaka Samvat numbers it 1866.
