Panchang in Ipameri, Goiás, Brazil Fri 25 May 2018

Smartas test Ekadashi at sunrise: it holds sunrise on Fri 25 May only, at 06:34: Fri 25 May. Vaishnavas test arunodaya: Dashami ended at 09:48 Thu, before it (04:58–06:34).

Padmini Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 06:34 here. Dashami ended at 09:48 Thu, before it. Ekadashi ends at 09:17, when the lead reaches 132°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

The night of Thu 24 May ran from sunset 17:45 Thu to sunrise 06:34, 12 h 49 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:34 Sat, splits into 8 choghadiyas of 1 h 36 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 4 at 170°. It leaves at 11:28, for Chitra.

Add the Sun's and the Moon's places among the stars: 40° + 170.6° = 210.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 11:05, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 21:30 Thu, when the lead reached 126°; Vishti runs until 09:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:34 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 08:47 Tue to 13 Jun 16:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 03:06 Fri, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 10:11 Sat. Since then the Sun has moved 67.2° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
