Online Unix Timestamp and Date Converter

  1. 1

    Paste timestamp and select precision

    Paste a 10-digit second-level or 13-digit millisecond-level value in the timestamp input box, select the corresponding precision setting (second or millisecond) based on the source, and the tool will instantly validate the input validity.

  2. 2

    View date and time in the selected timezone

    Conversion results are formatted and displayed according to the currently selected timezone; switching timezones immediately recalculates, and frequently used timezones support keyword quick filtering.

  3. 3

    Reverse convert dates back to Unix timestamps

    Select or enter date and time in the reverse conversion area; after the tool validates legality, it outputs the corresponding Unix value according to the current precision level.

  4. 4

    Copy real-time timestamps or conversion results

    The page displays the current Unix timestamp in real-time, supporting start, stop, and manual refresh; both real-time values and any conversion result can be copied with one click.

Features Overview

Convert between timestamps and dates, monitor live Unix time, select timezones, and switch between seconds or milliseconds precision.

Tool Description

Free Unix timestamp to date converter online. Convert Unix timestamp to date, date to Unix timestamp, inspect current Epoch time, switch between seconds and milliseconds, and compare results across time zones with everything processed locally in your browser.

Capabilities Checklist

  • Displays the current Unix time in real-time (following the selected timezone), with options to start, stop, and refresh the timer.
  • Supports second/millisecond precision switching: second-level mode outputs 10-digit, millisecond-level mode outputs 13-digit Unix timestamps, matching the source data digit count.
  • Provides common timezone selection (including Beijing time) and supports quick keyword filtering.
  • Convert both Unix → date and date → Unix with validation and helpful feedback.
  • Provide copy shortcuts with clear success messaging.
  • After switching timezones, the real-time timestamp and conversion results are immediately recalculated based on the new timezone.
  • Built-in developer quick reference with code snippets in mainstream programming languages for retrieving and converting Unix timestamps.
  • Provides instant prompts when input is invalid, ensuring no incorrect conversion results are output.

Frequently Asked Questions

What timestamp format does this tool support?
Supports 10-digit second-level and 13-digit millisecond-level Unix timestamps. A Unix timestamp represents the number of seconds (or milliseconds for millisecond-level) elapsed since January 1, 1970, 00:00:00 UTC, and is timezone-independent, widely used in programming and database scenarios. For concepts and usage examples in various languages, you can read the article "The Complete Guide to Unix Timestamps".
What result do I get after pasting a timestamp?
This tool instantly converts numerical values to date and time based on the current precision setting and formats the display according to the selected timezone. Switching between second/millisecond precision recalculates based on the new setting, and provides a prompt when input is invalid.
What operations are available in the real-time timestamp area?
The page displays the current Unix timestamp in real-time with continuous refresh, supporting start, stop, and manual refresh functions to capture specific moments. Click the copy button to copy the current value.
What do 10-digit and 13-digit timestamps correspond to?
They correspond to second-level and millisecond-level precision respectively: 10-digit (e.g., 1700000000) represents the number of seconds elapsed since the Unix epoch, and 13-digit (e.g., 1700000000000) represents milliseconds, commonly used in JavaScript and modern APIs. Select the corresponding option in the precision setting before conversion.
Does the conversion result change after switching timezones?
Yes. Both the real-time timestamp and all conversion results are calculated and displayed based on the currently selected timezone. Switching timezones immediately recalculates; common timezones (including Beijing time Asia/Shanghai) support keyword filtering.
What input methods are supported for date-to-timestamp conversion?
In the reverse conversion area, select values through the date and time picker, or use "Use current time" to quickly fill in. After the tool validates the input, it outputs either a 10-digit second value or 13-digit millisecond value based on the current precision setting.
