That is close enough to midnight which the complete Moon will be on the following day in Coordinated Universal Time (UTC), therefore many calendars will demonstrate the entire Moon on December 30, 2020.
From the 1930’s that the Maine Farmer’s Almanac started publishing”Indian” titles for the complete Moons, linking these titles into the European months. I tie these Moon titles to the seasons instead of weeks (for reasons I’ve explained in previous postings), therefore the titles I use will likely probably be off a month from different sources before the summer of 2021. By season, as the first full Moon of winter, the Algonquin tribes of what is now the southern and northern United States termed the Wolf Moon, by the packs of wolves which howled hungrily outside the cities amid the cold and deep snows of winter. The following title is Ice Moon. By month the Entire Moon December is called the Cold Moon.
The plane of the Moon’s orbit around the Earth almost matches the plane of the Earth’s orbit around Sunlight. After the route of the Sun looks lowest in the skies for the calendar year, the route of the entire Moon’s reverse sunlight seems highest in the skies. For your Washington, DC, region, on Tuesday evening, December 29, 2020, moonrise will probably be at 4:32 PM, sunset is going to be 23 minutes afterwards at 4:55 PM, the Moon will hit its high point for the nighttime (75.8 degrees over the horizon) shortly after midnight at 12:15 AM on Wednesday morning, sunrise will be at 7:26 AM, and moonset is going to be 33 minutes afterwards at 7:59 AM EST.. The Moon will be in the skies for a total of 15 hours 27 minutes, with 14 hours 31 minutes if the Sun is down, which makes Tuesday night into Wednesday afternoon, December 29 to 30, 2020, the maximum complete Moon night of this year.
For the Buddhists of Sri Lanka, this can be Unduvap Poya. The Buddha is believed to have reached Enlightenment by meditating under a Bodhi Tree at India. From the 3rd century BCE, Sangamitta Theri, the daughter of Emperor Asoka and creator of the order of Buddhist nuns in Sri Lanka, attracted a branch of the tree to Sri Lanka. The sapling was planted in 288 BC by King Devanampiya Tissa at the Mahamevnāwa Park at Anuradhapura, Sri Lanka, where it still grows now, which makes it the oldest surviving human-planted tree with a known planting date.
We might also call this Chang’e Moon, following the 3 Chinese lunar landers that started this season in 2013, 2018, and 2020. These assignments receive their name in the Chinese goddess of the Moon, Chang’e, who dwelt on the Moon along with her pet bunny, Yutu. The Chang’e 3 lander and its company Yutu rover started on December 1 and also landed on the Moon on December 14 2013. The Chang’emails 4 lander and its company Yutu-2 rover started December 7, 2018 and landed January 3, 2019.
In the majority of lunar and lunisolar calendars that the months shift with the new Moon and full Moons collapse in the center of the lunar month. This Complete Moon is the Center of the eleventh month of the Chinese calendar, Tevet from the Hebrew calendar, also Jumada al-awwal from the Islamic calendar.
As usual, the sporting of appropriately celebratory celestial apparel is encouraged in honour of the complete Moon. Stay hot, but make the most of those ancient nightfalls to escape, look upward, and discuss the wonders of the skies!
