Panchang in Ipameri, Goiás, Brazil Thu 21 May 1998

Smartas test Ekadashi at sunrise. It begins at 08:27 on Thu 21 May, after that sunrise (06:32), and ends at 05:37 on Fri 22 May, before the next (06:32 Fri): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Thu 21 May.

Apara Ekadashi: every date in Ipameri

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, 06:32 here. Navami ended at 10:52 Wed, before it. Dashami ends at 08:27, when the lead reaches 300°. The lead passed 180° at the full moon of 11 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 08:27 and ended at 05:37 Fri, between the sunrises of 06:32 and 06:32 Fri. Thursday reads Dashami and Friday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Wed 20 May ran from sunset 17:46 Wed to sunrise 06:32, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 17:46, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:46 to 06:32 Fri, splits into 8 choghadiyas of 1 h 35 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 01:25 Fri, for Revati.

Add the Sun's and the Moon's places among the stars: 36.3° + 335.2° = 371.5°, one full turn and 11.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 09:20, then Priti.

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 21:42 Wed, when the lead reached 294°; Vishti runs until 08:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:32 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 25 May, finds it in Vrishabha and begins Jyeshtha.

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 25 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 1998, 00:13 Sat. Since then the Sun has moved 52.9° round the stars. Vikram Samvat numbers that year 2055; Shaka Samvat numbers it 1920.
