Panchang in Ipameri, Goiás, Brazil Sun 14 Dec 1975

Gita Jayanti follows the tithi at sunrise. Ekadashi runs from 06:03 on Sat 13 Dec to 08:17 on Sun 14 Dec, so it holds sunrise only on Sun 14 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 Sun 14 Dec only, at 05:31: Sun 14 Dec. Vaishnavas test arunodaya: Dashami ended at 06:03 Sat, 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 06:03 Sat, before it. Ekadashi ends at 08:17, when the lead reaches 132°. The lead passed 0° at the new moon of 2 Dec, so the Moon is waxing: Shukla paksha.

The night of Sat 13 Dec ran from sunset 18:42 Sat to sunrise 05:31, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 18:42, 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, 18:42 to 05:32 Mon, 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 3 at 6°40′. It leaves at 14:16, for Bharani.

Add the Sun's and the Moon's places among the stars: 238.2° + 8.9° = 247.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 16:52, 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 ended at 19:13 Sat, when the lead reached 126°; Vishti runs until 08:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:32 Mon, so the hours after midnight still belong to Raviwara.

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, 1 Jan, 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 2 Dec, 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: 11 Apr 1975, 13:38 Fri. Since then the Sun has moved 240.5° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
