Changing Dates for the Most Recent Commit
You can backdate the author date and commit date of your last commit and then push it. To change the author date:
git commit --amend --no-edit --date="Sun Mar 21 13:53:21 2021 -0500"
To change the commit date:
$GIT_COMMITTER_DATE="Sun Mar 21 13:53:21 2021 -0500" git commit --amend --no-edit
See both dates of the commits:
git log --pretty=fuller
If you have the commit pushed to remote, you will need to force push the backdated local commit to overwrite the remote one.
git push -f origin main
Changing Dates on Multiple Commits in the History
To pick the commits you want to edit among the last 5 commits:
git rebase -i HEAD~5
This will open your text editor. Replace the word
reword for the commits for which you want to edit the commit message, or replace it with
edit to amend it (we will use this to change dates). Repeat the steps above for editing author date or commit dates and use the following to proceed to edit the next commit each time.
git rebase --continue
Alternatively, you can use the following to stop after each commit starting from the one listed and editing as needed.
git rebase --interactive '8aca69e^'
