Convert UK dates to US format for forms and spreadsheets
You have dates from a UK supplier invoice, a British spreadsheet, or an EU CRM export. A US portal wants MM/DD/YYYY. This converter assumes every input is DD/MM/YYYY and outputs American format — no format picker needed.
Common scenarios
- US visa or tax form — date of birth from UK passport
- American vendor portal — paste UK invoice dates
- Cross-border CSV — normalize UK column before US Excel import
- API payload — convert display format while keeping ISO internally
How this page differs
- Locked UK → US — no format confusion
- 3-column preview — UK Input | US Output | ISO
- Example table — see conversions before you paste
Ambiguous date? Check it first. Mixed sources or need ISO export? Use Date Format Fixer.
FAQ
How do I convert 28/05/2026 to US format?
28/05/2026 is 28 May 2026 in UK format. This tool outputs 05/28/2026 for US forms. Paste UK dates one per line and copy the US column.
Why is input locked to UK/EU format?
This page is specifically for people who have DD/MM/YYYY dates (UK invoices, EU exports, British spreadsheets) and need MM/DD/YYYY for US systems.
What about dates like 03/04/2025?
That date is ambiguous — 3 April vs 4 March. This tool flags it and suggests using the Ambiguous Date Checker before converting.
Can I convert a whole column for a US visa application?
Yes. Paste your UK date column, review the US Output preview, and copy or download CSV. Double-check any flagged ambiguous rows.
Should I use Date Format Fixer instead?
Use this page when you know input is UK and output should be US. Use Date Format Fixer when source format is mixed or you need ISO output.
