In British English, the day is followed by the month, which is then followed by the year. E.g. 06/12/2022 or 6 December 2022. Alternative formats would be: 06-12-2022, 06.12.2022, 6th December 2022, etc.
On the other hand, in American English, usually the month comes before the day, which is then followed by the year. E.g. 12/06/2022 or December 6 2022. Like in the example above, alternative formats for this example would be: 12-06-2022, 12.06.2022, December 12th 2022, etc.
