Change dates of multiple git commits

Interactive rebase can change one commit at a time. When you need to rewrite timestamps across a whole feature branch, a spreadsheet is faster and safer to review.

Why not amend or rebase stop-by-stop?

• git commit --amend only touches the tip commit
• git rebase -i with exec/env filters is easy to get wrong mid-list
• filter-branch is deprecated and awkward for date-only edits

Comparison of tools: git-edit-date vs amend, rebase, filter-branch.

Bulk workflow

1. git-edit-date export -o commits.csv
2. Edit author_date / committer_date on as many rows as you need
3. git-edit-date apply -file=commits.csv
4. git push --force-with-lease if the branch was already on the remote

Full walkthrough with examples: how to change git commit dates.

Tips

• Leave unchanged rows alone — only edited metadata is applied
• Keep RFC3339 timestamps with timezone offsets
• Do not edit the hash column
