Panchang in Diffa, Niger Sat 23 Mar 2013

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 23 Mar only, at 06:11: Sat 23 Mar. Vaishnavas test arunodaya: Dashami ended at 11:40 Fri, before it (04:35–06:11).

Amalaki 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, 06:11 here. Dashami ended at 11:40 Fri, before it. Ekadashi ends at 12:45, when the lead reaches 132°. The lead passed 0° at the new moon of 11 Mar, so the Moon is waxing: Shukla paksha.

The night of Fri 22 Mar ran from sunset 18:20 Fri to sunrise 06:11, 11 h 51 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:11 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 06:11 Sun, 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 05:46 Sun, for Magha.

Add the Sun's and the Moon's places among the stars: 338.7° + 107.5° = 446.2°, one full turn and 86.2°. 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 18:45, 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 ended at 00:18, when the lead reached 126°; Vishti runs until 12:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:11 to 06:11 Sun, so the hours after midnight still belong to Shaniwara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 10 Apr, finds it in Meena and begins Chaitra.

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 11 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 15:37 Thu. Since then the Sun has moved 360.4° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
