Panchang in Ipameri, Goiás, Brazil Sat 15 Dec 1979

Smartas test Ekadashi at sunrise. It holds both sunrises, 05:31 on Fri 14 Dec and 05:32 on Sat 15 Dec. Ekadashi (04:56 Fri 14 Dec to 06:23 Sat 15 Dec) and Dwadashi (06:23 Sat 15 Dec to 07:08 Sun 16 Dec) are both longer than their day; when both grow, Smartas take the later day: Sat 15 Dec. Vaishnavas test arunodaya: on Fri 14 Dec Dashami lasts until 04:56, inside it (03:55–05:31); on Sat 15 Dec Ekadashi holds all of it.

Saphala Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 05:32 here. Dashami ended at 04:56 Fri, before it. Ekadashi ends at 06:23, when the lead reaches 312°. The lead passed 180° at the full moon of 3 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:56 Fri, before sunrise at 05:31 Fri, and ends at 06:23, after the next sunrise at 05:32. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 14 Dec ran from sunset 18:42 Fri to sunrise 05:32, 10 h 50 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 Sun, 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 2 at 190°. It leaves at 23:07, for Vishakha.

Add the Sun's and the Moon's places among the stars: 239.2° + 190.8° = 430°, one full turn and 70°. 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 23:14, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava ended at 17:45 Fri, when the lead reached 306°; Balava runs until 06:23.

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

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 16 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: 27 Mar 1979, 23:59 Tue. Since then the Sun has moved 255.9° round the stars. Vikram Samvat numbers that year 2036; Shaka Samvat numbers it 1901.
