Panchang in Davinópolis, Maranhão, Brazil Mon 16 Jun 1997

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 16 Jun only, at 06:16: Mon 16 Jun. Vaishnavas test arunodaya: Dashami ended at 18:49 Sun, before it (04:40–06:16).

Nirjala Ekadashi: every date in Davinópolis

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, 06:16 here. Dashami ended at 18:49 Sun, before it. Ekadashi ends at 19:43, when the lead reaches 132°. The lead passed 0° at the new moon of 5 Jun, so the Moon is waxing: Shukla paksha.

The night of Sun 15 Jun ran from sunset 18:04 Sun to sunrise 06:16, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:04, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:04 to 06:16 Tue, splits into 8 choghadiyas of 1 h 31 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 1 at 186°40′. It leaves at 07:01 Tue, for Vishakha.

Add the Sun's and the Moon's places among the stars: 61.4° + 186.9° = 248.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 15:05, then Shiva.

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 runs until 07:21, when the lead reaches 126°; Vishti until 19:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:16 Tue, so the hours after midnight still belong to Somawara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 4 Jul, finds it in Mithuna and begins Ashadha.

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 5 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1997, 08:01 Mon. Since then the Sun has moved 67.5° round the stars. Vikram Samvat numbers that year 2054; Shaka Samvat numbers it 1919.
