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 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.

How to use this tool?

1. Use the date-and-time picker to select your target date and time, or type directly into the input fields. 2. Select a time zone from the dropdown — the tool defaults to your local browser time zone. 3. All output formats (Unix seconds, Unix milliseconds, ISO 8601, RFC 2822, etc.) update instantly as you change the date or time. 4. Click the "Copy" icon next to any format to copy that specific result to your clipboard. 5. Use the "Now" button to auto-populate the current date and time for a quick starting point. 6. Adjust the time zone dropdown to see how the same moment maps to different UTC offsets across regions.
