Panchang in Ipameri, Goiás, Brazil Thu 11 Dec 2081

Gita Jayanti follows the tithi at sunrise. Ekadashi runs from 22:06 on Wed 10 Dec to 00:03 on Fri 12 Dec, so it holds sunrise only on Thu 11 Dec, at 05:31. No text giving Gita Jayanti’s time was found; sunrise is Tithika’s convention.

Gita Jayanti: every date in Ipameri

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 11 Dec only, at 05:31: Thu 11 Dec. Vaishnavas test arunodaya: Dashami ended at 22:06 Wed, before it (03:55–05:31).

Mokshada 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, 05:31 here. Dashami ended at 22:06 Wed, before it. Ekadashi ends at 00:03 Fri, when the lead reaches 132°. The lead passed 0° at the new moon of 30 Nov, so the Moon is waxing: Shukla paksha.

The night of Wed 10 Dec ran from sunset 18:40 Wed to sunrise 05:31, 10 h 51 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 18:41, 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, 18:41 to 05:31 Fri, 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 08:46, for Ashwini.

Add the Sun's and the Moon's places among the stars: 235° + 358.4° = 593.4°, one full turn and 233.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 17:43, then Parigha.

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 11:09, when the lead reaches 126°; Vishti until 00:03 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:31 Fri, so the hours after midnight still belong to Guruwara.

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, 30 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 30 Nov, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2081, 05:16 Wed. Since then the Sun has moved 239.8° round the stars. Vikram Samvat numbers that year 2138; Shaka Samvat numbers it 2003.
