Panchang in Ipameri, Goiás, Brazil Wed 22 Dec 1909

Gita Jayanti follows the tithi at sunrise. Ekadashi begins at 05:39 on Wed 22 Dec, after that sunrise, and ends at 03:14 on Thu 23 Dec, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 22 Dec. No text giving Gita Jayanti’s time was found; sunrise is Tithika’s convention.

Mokshada Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 05:35 here. Navami ended at 08:06 Tue, before it. Dashami ends at 05:46, when the lead reaches 120°. The lead passed 0° at the new moon of 12 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:46 and ended at 03:21 Thu, between the sunrises of 05:35 and 05:36 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 21 Dec ran from sunset 18:46 Tue to sunrise 05:35, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 18:47, 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, 18:47 to 05:36 Thu, 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 15:52, for Bharani.

Add the Sun's and the Moon's places among the stars: 247.3° + 7.2° = 254.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 00:36 Thu, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 18:57 Tue, when the lead reached 114°; Garaja runs until 05:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:36 Thu, so the hours after midnight still belong to Budhawara.

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 15 Dec, inside the month. The next new moon, 11 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 12 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: 21 Mar 1909, 17:11 Sun. Since then the Sun has moved 269.3° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
