Maybe it was to make it look more official or something.

Did you see that old document they found in the archives?
Sloth B
Yeah, it's fascinating! I heard they plan to antedate it to show how things were back then.

Root Explanation

Antedate is formed from "ante-" (meaning before) and "datum" (meaning given or dated). The word refers to something that is dated earlier than the actual date.

Memory Tip

Think of 'ante-' meaning 'before' and 'datum' meaning 'given' — so antedate means to give a date that is before the actual date.
