Right. Johnson's pardon issued July 04, 1868. The Civil War ended April 9, 1865.

Carter's Vietnam pardon issued January 21, 1977. Vietnam War ended January 27, 1973 (Paris Peace Accords signing).

Both basically 3-year gaps after the fact. So to that end, Trump could sign a Jan6 pardon on his first day in office January 20, 2025. That's 4 years and 14 days but same general idea as the Civil War and Vietnam pardons.
