Frequently Asked Questions
What is ISO 8601?
ISO 8601 is the international standard for date and time representation. The format YYYY-MM-DD avoids ambiguity between US (MM/DD) and EU (DD/MM) conventions.
What is a Unix timestamp?
A Unix timestamp counts the number of seconds since January 1, 1970 (UTC). It is widely used in programming and databases.
What is RFC 2822?
RFC 2822 defines the date format used in email headers and HTTP protocols. Example: "Mon, 01 Jan 2024 00:00:00 GMT".
Is my data processed on a server?
No. All formatting happens in your browser using JavaScript and the Intl API. Nothing leaves your device.
