How to use this tool

Choose the input order before conversion. Days and months must have two digits; years have four.

Limits and behavior

Uses the Gregorian calendar for years 1900–2100. Dates must be exact YYYY-MM-DD values. Calendar days are counted at UTC midnight, independent of daylight saving. Ambiguous numeric dates are interpreted only by the format you select. Time components and automatic locale guessing are excluded. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.

Change a date into a different format

Convert supported dates between display conventions while explicitly identifying the original day, month and year order.

How can I avoid ambiguous dates such as 04/05?

Specify the source ordering instead of guessing whether the month or day comes first.
