How Can I change the date of a git commit

Question

I need to push some code upstream into my repo. However I would like to see if It is possible to set the date of the commit/push to be something other than the current the date.This would mean if someone visited my github page and my desired date for the push was 00/00/00 it would show as 00/00/00 and NOT the current date.Is there anyway to do this?

Answer 1

You can change the date of last commit:

git commit --amend --no-edit --date=now

or input date:

git commit --amend --no-edit --date="2020.11.02 12:00"

Answer 2

You can use the environment variable GIT_COMMITTER_DATE to update commit date as well.

export GIT_COMMITTER_DATE='Wed Dec 21 11:51:39 IST 2022'
git commit --amend --no-edit --date='Wed Dec 21 11:51:39 IST 2022'
unset GIT_COMMITTER_DATE

To see if your change has taken effect,

git log --pretty=fuller

(of course, you will need to do a force-push, if you have already pushed the commit to upstream)
