Panchang in Ipameri, Goiás, Brazil Wed 16 Apr 1913

Smartas test Ekadashi at sunrise. It begins at 08:58 on Wed 16 Apr, after that sunrise (06:15), and ends at 06:12 on Thu 17 Apr, before the next (06:15 Thu): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Wed 16 Apr.

Kamada Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:22 here. Navami ended at 11:34 Tue, before it. Dashami ends at 09:04, when the lead reaches 120°. The lead passed 0° at the new moon of 6 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 09:04 and ended at 06:18 Thu, between the sunrises of 06:22 and 06:22 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 15 Apr ran from sunset 18:03 Tue to sunrise 06:22, 12 h 18 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 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 Thu, 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 1 at 120°. It leaves at 01:44 Thu, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 3.1° + 121.6° = 124.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 19:40, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 22:21 Tue, when the lead reached 114°; Garaja runs until 09:04.

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

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, 6 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 6 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: 6 Apr 1913, 14:47 Sun. Since then the Sun has moved 9.4° round the stars. Vikram Samvat numbers that year 1970; Shaka Samvat numbers it 1835.
