SQL Date Format Converter
SQL Date Format Converter: free, instant and private. 31/01/2026 and 01/31/2026 are the same day written in two conventions — and 03/04/2026 is ambiguous everywhere.
How the SQL Date Format Converter works
The SQL Date Format Converter takes Date (e.g. 2026-01-31, 31/01/2026, Jan 31 2026) and returns the answer instantly — no button to hunt for, no page reload. 31/01/2026 and 01/31/2026 are the same day written in two conventions — and 03/04/2026 is ambiguous everywhere. ISO 8601 is the only format that sorts correctly as text, which is why databases and APIs standardise on it.
Enter your own numbers to replace the example values; the result panel updates as you type. Everything runs in this single page, so nothing you enter leaves your device.
Formula used
one parse → many renderings: ISO 8601, DD/MM/YYYY, MM/DD/YYYY, long form, epoch
| Symbol | Meaning |
|---|---|
| ISO 8601 | YYYY-MM-DD — the unambiguous machine format |
| DD/MM vs MM/DD | the day/month order that keeps confusing international forms |
| epoch | seconds since 1970-01-01 UTC |
