What timestamp formats are supported?

The calculator supports ISO 8601 (e.g., 2025-01-15T10:30:00Z), Unix timestamps (seconds or milliseconds), natural language (e.g., 'tomorrow at 3pm', 'next Friday'), and RFC formats. Both timestamps are automatically converted to UTC for accurate calculation.

How does the calculator handle different timezones?

The calculator automatically detects timezones from the input timestamps and converts both to UTC for accurate calculation. The output shows the time difference in a timezone-agnostic format (duration only).

What output formats are available?

The calculator provides results in multiple formats: total days, hours, minutes, seconds, milliseconds, human-readable format (e.g., '2 days, 3 hours, 15 minutes'), ISO 8601 duration format (e.g., 'P2DT3H15M'), and a detailed breakdown. All formats can be copied to clipboard with one click.

Can I use this calculator with an API?

Yes! The time calculator is available as a REST API endpoint at /api/time-calculator. You can integrate it into your applications, automation workflows, or use it with tools like Zapier.
