Date Format Converter
Convert a date into any format you need (DD/MM/YYYY, MM-DD-YYYY, YYYY.MM.DD and more). Free, instant, and calculated right in your browser.
Paste in a date. Like 03/14/2026, 2026-03-14, or March 14, 2026, and convert it to whatever format you actually need, whether that's ISO 8601 for a database, a US or European style for a form, or a custom pattern for a report.
How to use it
- Paste or type the date you want to convert
- Choose the output format (ISO, US, European, or a custom pattern)
- Copy the reformatted date
Frequently asked questions
- Why does my date look right but convert wrong?
- Ambiguous dates like 03/04/2026 can be read as March 4 or April 3 depending on locale. If the result looks off, check which input format (MM/DD/YYYY vs DD/MM/YYYY) is selected before converting.
- Can I convert a whole list of dates at once?
- Yes, paste multiple dates (one per line) and each one is reformatted using the same input and output pattern, so you don't have to convert them one at a time.
- Does this handle ISO 8601 with timezones?
- Yes, it recognizes ISO 8601 strings including the T separator and Z or +00:00 offsets, and can strip the time portion down to just the date if that's all you need.
- Is my date data sent anywhere?
- No, all parsing and reformatting happens locally in your browser, so nothing you type ever leaves your machine.
