Frequently Asked Questions

Everything you need to know about date formats and how to convert between them.

What date formats are supported?

MorphFlux supports ISO 8601 (2024-01-15T10:30:00Z), Unix timestamps (seconds and milliseconds), US format (01/15/2024), European format (15/01/2024), long format (January 15, 2024), and relative format (3 days ago).

What is ISO 8601 date format?

ISO 8601 is the international standard for date and time representation. The format is YYYY-MM-DD for dates and YYYY-MM-DDTHH:MM:SSZ for date-times. It is unambiguous and widely used in APIs and databases.

How do I convert MM/DD/YYYY to DD/MM/YYYY?

Paste your US format date (MM/DD/YYYY) into the converter above. The European format (DD/MM/YYYY) is shown instantly alongside all other supported formats.

Why do different countries use different date formats?

The US uses MM/DD/YYYY, most of Europe uses DD/MM/YYYY, and the ISO standard uses YYYY-MM-DD. These differences cause frequent confusion in international data exchange, making a format converter essential.

Is my data sent to a server?

No. All conversion happens locally in your browser using JavaScript and Day.js. Your data never leaves your device.
