Follow the form, then the country.

1

Follow the form

If the box says MM/DD/YYYY, use exactly that.

2

Otherwise, follow the country

US: month first. UK and most of Europe: day first.

3

When in doubt, spell it out

'4 March 2026' can't be misread.

International contracts

For contracts between countries, writing the month as a word ('4 March 2026') or using ISO dates avoids the most common mix-up.
