About this tool
Covers the formats people most often need to match: UK (DD/MM/YYYY), US (MM/DD/YYYY), ISO 8601, and a written-out long form.
Pick a date and see it written fifteen ways, each with its own Copy button. The UK and US numeric styles are the classic source of confusion: 04/05/2026 is 4 May in Britain but April 5 in America, which is why ISO 8601 (2026-05-04) is the safest choice for anything shared internationally, and it sorts correctly as text too. The list also includes the ordinal form for letters and invitations (Monday 4th May 2026), the ISO week date used in business planning, the day of the year, the Unix timestamp for midnight UTC, and the formats used in email headers and SQL.
