Panchang in Davinópolis, Maranhão, Brazil Thu 4 Aug 1983

Smartas test Ekadashi at sunrise. It begins at 07:51 on Thu 4 Aug, after that sunrise (06:19), and ends at 05:45 on Fri 5 Aug, before the next (06:18 Fri): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Thu 4 Aug.

Kamika Ekadashi: every date in Davinópolis

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:19 here. Navami ended at 09:13 Wed, before it. Dashami ends at 07:51, when the lead reaches 300°. The lead passed 180° at the full moon of 24 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:51 and ended at 05:45 Fri, between the sunrises of 06:19 and 06:18 Fri. Thursday reads Dashami and Friday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Wed 3 Aug ran from sunset 18:12 Wed to sunrise 06:19, 12 h 7 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 18:12, 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 night here, 18:12 to 06:18 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Rohini spans 40°00′–53°20′; the Moon entered its pada 3 at 46°40′. It leaves at 17:13, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 107.8° + 47° = 154.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 14:41, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 20:37 Wed, when the lead reached 294°; Vishti runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:18 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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 8 Aug, finds it in Karka and begins Shravana.

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 8 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Apr 1983, 04:58 Wed. Since then the Sun has moved 108.6° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
