How to change author, committer, and date of some commit?

Find a hash of your commit (e.g. HASH_OF_COMMIT_TO_CHANGE)

Run this command with the date you want this commit to happen on, and new names and emails:

git -c user.name="NEW NAME" -c user.email="new_email@gmail.com" commit --amend --date="Tue Nov 20 03:00 2018 +0100" --author="NEW NAME <new_email@gmail.com>"

This will return you a newly created commit hash: HASH_OF_NEW_COMMIT.

git replace HASH_OF_COMMIT_TO_CHANGE HASH_OF_NEW_COMMIT
git filter-branch -- --all
git replace -d HASH_OF_COMMIT_TO_CHANGE
git push --force-with-lease origin master
