Panchang in Diffa, Niger Tue 19 Jan 2016

Smartas test Ekadashi at sunrise. It begins at 07:49 on Tue 19 Jan, after that sunrise (06:36), and ends at 06:13 on Wed 20 Jan, before the next (06:36 Wed): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Tue 19 Jan.

Pausha Putrada 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, 06:36 here. Navami ended at 09:35 Mon, before it. Dashami ends at 07:49, when the lead reaches 120°. The lead passed 0° at the new moon of 10 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:49 and ended at 06:13 Wed, between the sunrises of 06:36 and 06:36 Wed. Tuesday reads Dashami and Wednesday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Mon 18 Jan ran from sunset 18:03 Mon to sunrise 06:36, 12 h 33 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:36 to 18:03, 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 night here, 18:03 to 06:36 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Krittika spans 26°40′–40°00′; the Moon entered its pada 3 at 33°20′. It leaves at 17:15, for Rohini.

Add the Sun's and the Moon's places among the stars: 274.5° + 33.8° = 308.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 01:25 Wed, then Brahma.

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 20:41 Mon, when the lead reached 114°; Garaja runs until 07:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:36 to 06:36 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 8 Feb, finds it in Makara and begins Magha.

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 10 Jan, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 10:36 Fri. Since then the Sun has moved 299.1° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
