How to use it
- Enter date mm/dd/yyyy.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
The month must be 1 to 12 and the day must exist in that month; then the two swap: MM/DD/YYYY becomes DD/MM/YYYY.
Example
Inputs: Date MM/DD/YYYY = 07/04/2026. Result: DD/MM/YYYY: 04/07/2026; Weekday: Saturday.
07/04/2026
04/07/2026
Limits and caveats
- The year must have four digits.
- A date whose day is 12 or less is valid either way, so check where it came from.
