HAPPY SOLSTICE TO ALL
Winter/Summer Solstice (the longest/shortest night) and a full moon and a full lunar eclipse is a rare event, INDEED! The US Naval Observatory inspected a list of eclipses going back 2000 years. Since the first year of the study, they say there is only one previous instance of an eclipse matching the same calendar date as the solstice, and that is 1638 DEC 21. But whether it was in 1638 or in 1703, as stated in the video, all agree that it is a rare and special day. Perhaps, it might be that way with our differences -- we can disagree on the details AND see something larger.
MAY IT BE and MAY ALL BE BLESSED
A neat animation of the eclipse, including times, is here. And there's lots more information about solstice here and here.
