Panchang in Ipameri, Goiás, Brazil Sun 15 Dec 1968

Smartas test Ekadashi at sunrise. It begins at 07:33 on Sun 15 Dec, after that sunrise (05:32), and ends at 05:17 on Mon 16 Dec, before the next (05:32 Mon): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Sun 15 Dec.

Saphala 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, 05:32 here. Navami ended at 09:03 Sat, before it. Dashami ends at 07:33, when the lead reaches 300°. The lead passed 180° at the full moon of 4 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:33 and ended at 05:17 Mon, between the sunrises of 05:32 and 05:32 Mon. Sunday reads Dashami and Monday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Sat 14 Dec ran from sunset 18:43 Sat to sunrise 05:32, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 18:43, 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, 18:43 to 05:32 Mon, 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 2 at 176°40′. It leaves at 18:40, for Swati.

Add the Sun's and the Moon's places among the stars: 240° + 178.9° = 418.9°, one full turn and 58.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 17:45, then Atiganda.

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 20:23 Sat, when the lead reached 294°; Vishti runs until 07:33.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:32 Mon, so the hours after midnight still belong to Raviwara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 19 Dec, finds it in Dhanu and begins Pausha.

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 19 Dec, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 1968, 19:47 Thu. Since then the Sun has moved 255.1° round the stars. Vikram Samvat numbers that year 2025; Shaka Samvat numbers it 1890.
