Backdate Edit Meaning

1.

When you have a school project that you were told about six months ago, but you did it the night it was due, you backdate it by putting dating a day from earlier to make it seem like you've been working on it for a while. Also very useful when you're doing an assignment the day its due.

Joe had just finished his history paper second period on the day it was due; in the heading, he backdated it a week so that the teacher would believe he didn't do a half-ass job on it.
