Panchang in Diffa, Niger Tue 27 Mar 2018

Smartas test Ekadashi at sunrise: it holds sunrise on Tue 27 Mar only, at 06:09: Tue 27 Mar. Vaishnavas test arunodaya: Dashami ended at 23:13 Mon, before it (04:33–06:09).

Kamada Ekadashi: every date in Diffa

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, 06:09 here. Dashami ended at 23:13 Mon, before it. Ekadashi ends at 21:01, when the lead reaches 132°. The lead passed 0° at the new moon of 17 Mar, so the Moon is waxing: Shukla paksha.

The night of Mon 26 Mar ran from sunset 18:20 Mon to sunrise 06:09, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 18:20, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:20 to 06:08 Wed, splits into 8 choghadiyas of 1 h 28 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 4 at 103°20′. It leaves at 06:57, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 342.4° + 106.2° = 448.6°, one full turn and 88.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 13:41, then Dhriti.

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 runs until 10:07, when the lead reaches 126°; Vishti until 21:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:08 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 14 Apr, inside the month. The next new moon, 16 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 17 Mar, 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: 17 Mar 2018, 14:11 Sat. Since then the Sun has moved 9.6° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
