Panchang in Ipameri, Goiás, Brazil Sat 11 Feb 1961

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 11 Feb only, at 06:05: Sat 11 Feb. Vaishnavas test arunodaya: Dashami ended at 21:40 Fri, before it (04:29–06:05).

Vijaya 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, 06:05 here. Dashami ended at 21:40 Fri, before it. Ekadashi ends at 18:58, when the lead reaches 312°. The lead passed 180° at the full moon of 31 Jan, so the Moon is waning: Krishna paksha.

The night of Fri 10 Feb ran from sunset 18:49 Fri to sunrise 06:05, 11 h 16 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 to 18:48, 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 night here, 18:48 to 06:05 Sun, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Mula spans 240°00′–253°20′; the Moon entered its pada 2 at 243°20′. It leaves at 21:43, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 299.1° + 243.8° = 542.9°, one full turn and 182.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 11:52, then Vajra.

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 runs until 08:23, when the lead reaches 306°; Balava until 18:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:05 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 15 Feb, finds it in Kumbha and begins Phalguna.

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 15 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 1960, 04:37 Sun. Since then the Sun has moved 315.8° round the stars. Vikram Samvat numbers that year 2017; Shaka Samvat numbers it 1882.
