Date Standards & Formats
ISO 8601 (YYYY-MM-DDTHH:mm:ss.sssZ) is the international standard for exchanging date and time data.
RFC 2822 is the standard used for Internet Message Formats, commonly seen in email headers (e.g., Mon, 01 Jan 2024...).
Unix Timestamp represents time as seconds since the Epoch (1970-01-01).
JavaScript's `Date` object handles parsing and formatting based on the ECMAScript standard.
