Read an unfamiliar date, compare country formats and turn it into a clear ISO date.
Examples & helpYour date, in different formats
| Format | Date |

| ISO · YYYY-MM-DD | |
| DD.MM.YY | |

All rows show the same Gregorian calendar date. Two-digit years omit the century; use the full ISO date when the century matters. Country formatting follows your browser’s locale data.
Convert dates between US, UK and ISO formats
A date such as 03/04/2026 can mean March 4 or April 3. Pick the order before converting. This tool keeps the same Gregorian calendar day and changes how it is written; it does not move the date into a different time zone.
How to use this calculator
- Choose the input pattern. The supported typed patterns are YYYY-MM-DD, DD.MM.YY, MM.DD.YY and YYYY.MM.DD.
- Enter the date exactly in that pattern. For a two-digit year, choose its century explicitly.
- Choose a country and select Convert date format to compare the ISO date, dotted formats and country display.
Worked examples
Read the same digits month-first
- Start with
- 03.04.26 with MM.DD.YY and the 2000–2099 century.
- Result
- 2026-03-04 — Wednesday, 4 March 2026
Now 03 means March and 04 means the fourth day. The converter deliberately does not guess the order from an ambiguous number.
Common questions
What does YYYY-MM-DD mean?
It means four-digit year, two-digit month and two-digit day. For example, 2026-10-24 is October 24, 2026. This date-only ISO format does not specify a clock time or UTC offset.
Can I paste a date written with slashes?
The current input accepts only the selected pattern. For 03/04/2026, first establish whether it is day-first or month-first, then enter 03.04.26 with the matching order and century. Country output can use slashes.
Why do I have to choose a century?
A year written as 26 could mean 1926 or 2026. The century choice removes that ambiguity. Use a four-digit input year for dates outside those two centuries. Country displays show one common locale convention, not every format used there.
