Frequently Asked Questions

Does Date Diff Calculator show character-level differences?

Yes — both line-level and character-level changes are highlighted.

Why use a browser tool instead of the command line?

No installation, works on any device, and results are shareable via URL. CLI tools are still better for CI/CD pipelines.

Is my input collected for analytics?

No — client-side tools don't transmit your input. Standard page-view analytics may run, but your data is never included.
