Privacy: where the work happens
Everything you enter or choose is processed by JavaScript in your browser and never sent anywhere. Only the page code, and any library this tool needs, is downloaded from cdnjs or jsDelivr.

Does it handle daylight saving time?
Yes. It uses your browser’s built-in time zone database, so the offset for that date is applied.
