Panchang in Ipameri, Goiás, Brazil Wed 21 Sep 1988

Smartas test Ekadashi at sunrise. It begins at 08:31 on Wed 21 Sep, after that sunrise (06:03), and ends at 05:56 on Thu 22 Sep, before the next (06:02 Thu): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Wed 21 Sep.

Parsva 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, 06:03 here. Navami ended at 10:31 Tue, before it. Dashami ends at 08:31, when the lead reaches 120°. The lead passed 0° at the new moon of 11 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 08:31 and ended at 05:56 Thu, between the sunrises of 06:03 and 06:02 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 20 Sep ran from sunset 18:08 Tue to sunrise 06:03, 11 h 55 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:03 to 18:08, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:08 to 06:02 Thu, splits into 8 choghadiyas of 1 h 29 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 16:54, for Shravana.

Add the Sun's and the Moon's places among the stars: 154.9° + 273.5° = 428.4°, one full turn and 68.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 00:09 Thu, then Sukarma.

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 21:36 Tue, when the lead reached 114°; Garaja runs until 08:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:03 to 06:02 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 10 Oct, finds it in Kanya and begins Ashwina.

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 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1988, 23:02 Thu. Since then the Sun has moved 180.9° round the stars. Vikram Samvat numbers that year 2045; Shaka Samvat numbers it 1910.
