Flags will remain at half-mast and half-staff most of the month for Jimmy Carter's death. Jan. 9 will be a national day of mourning for his funeral.

Under President Joe Biden’s proclamation, flags will be at half-staff until a week after Trump’s Jan. 20 inauguration. Since ordering the flags lowered is a proclamation that a sitting president makes, Trump won’t be able to do anything about it until after he is inaugurated.
