Dates & time
Date format converter
Translate explicitly ordered numeric dates into unambiguous formats.
A clear answer. Here’s how.
Accepts numeric components separated consistently by /, - or ., using the input order you select. Requires a four-digit year and validates the Gregorian date without rollover. Reports ISO, DMY, MDY, English long date, ordinal day and ISO week date. Never guesses an ambiguous day/month order.
