Panchang in Ipameri, Goiás, Brazil Thu 27 Dec 1990

Smartas test Ekadashi at sunrise. It begins at 09:17 on Thu 27 Dec, after that sunrise (06:38), and ends at 06:34 on Fri 28 Dec, before the next (06:38 Fri): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Thu 27 Dec.

Pausha Putrada 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, 06:38 here. Navami ended at 11:23 Wed, before it. Dashami ends at 09:17, when the lead reaches 120°. The lead passed 0° at the new moon of 17 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 09:17 and ended at 06:34 Fri, between the sunrises of 06:38 and 06:38 Fri. Thursday reads Dashami and Friday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Wed 26 Dec ran from sunset 19:49 Wed to sunrise 06:38, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:38 to 19:49, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:49 to 06:38 Fri, splits into 8 choghadiyas of 1 h 21 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 12:00, for Bharani.

Add the Sun's and the Moon's places among the stars: 251.6° + 10.1° = 261.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 14:21, then Siddha.

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 22:25 Wed, when the lead reached 114°; Garaja runs until 09:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:38 to 06:38 Fri, so the hours after midnight still belong to Guruwara.

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, 15 Jan, 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 17 Dec, 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: 26 Mar 1990, 16:48 Mon. Since then the Sun has moved 269.4° round the stars. Vikram Samvat numbers that year 2047; Shaka Samvat numbers it 1912.
