Date to Timestamp Converter – Any Date to Unix, ISO & More
Convert any date and time to multiple timestamp formats — Unix seconds and milliseconds, ISO 8601, RFC 2822, and more — with timezone support and one-click copy.
What the result means
- Unix (seconds) — the number of seconds since 1 January 1970 (UTC). This is the value most APIs, databases, and log files expect.
- Unix (milliseconds) — the same point in time with millisecond precision, used by JavaScript and many JSON APIs.
- ISO 8601 — a sortable, machine-readable date such as 2024-01-01T12:00:00.000Z, ideal for config files and data exchange.
- RFC 2822 / UTC — a human-readable form used in email headers and HTTP responses.
Got a raw timestamp instead of a date? Reverse the conversion with the Unix Timestamp Converter.
These conversions also pair well with the rest of the Developer Toolkit.

What is this tool?
A date-to-timestamp converter transforms a human-readable date and time into the numeric and standardized string formats that computers, databases, and APIs use internally. Enter any date — past, present, or future — and the tool simultaneously outputs the Unix timestamp in seconds and milliseconds, the ISO 8601 string (e.g., "2025-06-01T12:00:00Z"), the RFC 2822 string used in email headers, and other common representations. It supports time zone selection so you can pin the conversion to the region that matters for your use case. Developers, data engineers, and QA testers use it daily when crafting API requests, writing test fixtures, or populating database records.
