Panchang in Diffa, Niger Wed 25 Apr 2018

Smartas test Ekadashi at sunrise. It begins at 06:16 on Wed 25 Apr, after that sunrise (05:51), and ends at 04:50 on Thu 26 Apr, before the next (05:50 Thu): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Wed 25 Apr.

Mohini Ekadashi: every date in Diffa

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, 05:51 here. Navami ended at 07:55 Tue, before it. Dashami ends at 06:16, when the lead reaches 120°. The lead passed 0° at the new moon of 16 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:16 and ended at 04:50 Thu, between the sunrises of 05:51 and 05:50 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 24 Apr ran from sunset 18:23 Tue to sunrise 05:51, 11 h 28 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:51 to 18:23, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:23 to 05:50 Thu, splits into 8 choghadiyas of 1 h 25 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 4 at 130°. It leaves at 10:35, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 10.8° + 130.6° = 141.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 14:21, then Dhruva.

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 19:04 Tue, when the lead reached 114°; Garaja runs until 06:16.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:51 to 05:50 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 15 May, finds it in Vrishabha and begins Jyeshtha.

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 16 Apr, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 14:11 Sat. Since then the Sun has moved 38° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
