Convert Unix timestamps to readable dates, or pick a date and time to get Unix seconds and milliseconds. Auto-detect chooses seconds or milliseconds, and results include ISO 8601 UTC, local time, and a relative phrase. Conversion runs in your browser.
Results update as you type. Auto-detect chooses seconds or milliseconds.

Convert Unix timestamps to readable dates, or pick a date and time to get Unix seconds and milliseconds. Auto-detect chooses seconds or milliseconds, and results include ISO 8601 UTC, local time, and a relative phrase. Conversion runs in your browser.
Use the Timestamp Converter form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
Example: open Timestamp Converter, enter a realistic set of inputs for your situation, and note the primary result. Change one input—such as an amount, rate, or option—and compare how the output changes so you can choose a scenario that fits your needs.
Second example: try edge cases that matter for your task—such as zero values, a different unit system, or a second file—and confirm the tool shows a clear result or a helpful validation message.
Choose Timestamp or Date & time. Paste a Unix timestamp (seconds or milliseconds, with auto-detect) or pick a local date and time. The tool shows Unix seconds, milliseconds, ISO 8601 UTC, local and UTC strings, and a relative time. Use Now fills the current moment. All conversion runs in your browser.
This tool runs in your browser for convenience. Results are estimates or transformations based on the inputs you provide and may not cover every edge case.
Values with an absolute magnitude of 100 billion or more are treated as milliseconds. Smaller values are treated as seconds. You can override this with the Unit control.
You get Unix seconds, Unix milliseconds, ISO 8601 UTC, a UTC string, your local date and time, and a relative phrase such as 2 hours ago.
No. Conversion runs locally in your browser and values are not stored.
