Over a Thousand years apart from each other, but both on Yom Kippur I think.
The Great White Throne Judgment, where God The Father is The Judge will be on the Yom Kippur proceeding The Tabernacles Festival when New Jerusalem descends.
The Bema Judgment where God The Son is The Judge will be in the Middle of Daniel's 70th Week. The Same Yom Kippur I link to The Rapture/Parusia.
It makes sense that Yom Kippur would be the Day of Judgment.
