Select US, EU or ISO, then type a date or use the adjacent calendar. The display format changes without changing the underlying date.
Date format changes presentation only: US uses MM/DD/YYYY and a 12-hour clock; EU uses DD/MM/YYYY and a 24-hour clock; ISO uses YYYY-MM-DD and a 24-hour clock. The same dates, instant, location, IP/Manual mode and language remain. Loading a page, choosing a country or region, choosing a timezone or switching to IP reapplies the location’s default format.
Worked example
03/04/2026 means March 4 in US format and April 3 in EU format.
