What date formats does the input accept?

The parser recognizes ISO 8601 (2025-12-01), US format (12/01/2025), European format (01/12/2025), and natural language dates (December 1, 2025). If your input isn't recognized, try a different format or use the date picker.

What format tokens are available for custom patterns?

Common tokens include YYYY (four-digit year), YY (two-digit year), MM (zero-padded month), M (month), DD (zero-padded day), D (day), HH (24-hour), hh (12-hour), mm (minutes), ss (seconds), and A (AM/PM). The full reference table is displayed in the tool.

How does the parser handle ambiguous dates like 01/02/2025?

Ambiguous dates are interpreted based on the selected input format. If you set the input format to US, 01/02/2025 is January 2nd. If set to European, it's February 1st. You can always verify the parsed date before formatting.

Can I include time in the formatted output?

Yes. If your input includes a time component, the formatted output includes it. Use time tokens like HH, mm, and ss in custom patterns to control how the time appears.

Does the tool handle timezone conversion?

The date formatter preserves the timezone of the input. For timezone conversion, use the timezone converter tool, which handles zone changes and DST adjustments.
