Unix Timestamp Converter

Convert Unix timestamps to readable dates and turn dates back into seconds or milliseconds.

Unix Timestamp Converter

Check the current Unix timestamp, convert a timestamp to a readable date, or convert a date and time back into seconds and milliseconds.

Convert Unix timestamps in both directions

Check the current Unix timestamp, convert a timestamp to a readable date, or convert a local date and time back into Unix seconds and milliseconds.

Timestamp to Date

Paste a Unix timestamp in seconds or milliseconds. The tool detects the unit automatically.

Date to Timestamp

Enter a local date and time to generate Unix timestamp seconds and milliseconds.

Date and time

Current Unix time updates automatically. Timestamp inputs are auto-detected as seconds or milliseconds.

How to use the Unix timestamp converter

  1. Check the live Current Unix Timestamp cards when you need the latest seconds or milliseconds value.
  2. Paste a Unix timestamp into Timestamp to Date. The tool automatically detects whether the value is in seconds or milliseconds.
  3. Enter a local date and time in Date to Timestamp to generate Unix timestamp seconds and milliseconds.
  4. Use Copy on the key results when you want to move values into logs, scripts, databases, or API requests.

Unix timestamp converter examples

  • Convert a 10-digit Unix timestamp from an API log into a readable local and UTC date.
  • Check whether a 13-digit database value is already stored in milliseconds.
  • Turn a deployment date and time into Unix seconds before scheduling a server-side job.
  • Convert a local datetime into a timestamp before sending it into a queue, API payload, or database field.

What this Unix timestamp converter does

This Unix timestamp converter lets you view the current Unix timestamp, convert a timestamp to a readable date, and convert a date and time back into Unix seconds or milliseconds.

It handles the most common Unix time tasks in one place, which makes it useful for API debugging, event logging, cron scheduling, database inspection, and quick development checks when you need an exact Unix time value without opening a shell.

Seconds vs milliseconds in Unix timestamps

Unix timestamps are often stored in either seconds or milliseconds. Many modern front-end logs and JavaScript systems use milliseconds, while APIs, databases, and backend tools frequently use seconds.

This tool automatically detects the likely unit for timestamp inputs and shows the normalized seconds and milliseconds values side by side, so it is easier to verify that you are using the right format.

Unix timestamp vs local time

A Unix timestamp is a universal numeric representation of time, but the readable date you see depends on the time zone used for display. That is why the same timestamp can look different in local time, UTC, server logs, or monitoring dashboards even though it points to the same moment.

This page helps by making the conversion explicit, so you can check whether a time issue is caused by the timestamp itself or by how the readable date is being displayed.

Common timestamp conversion mistakes

One of the most common errors is mixing up 10-digit seconds timestamps with 13-digit milliseconds timestamps. Another is assuming that a readable date shown in local time is wrong when the real issue is a time-zone mismatch.

A quick conversion check helps catch those problems before they spread into logs, database records, scheduled jobs, or API requests.

Unix timestamp converter FAQs

Does this tool detect seconds and milliseconds automatically?

Yes. Timestamp to Date automatically detects whether the input is most likely in seconds or milliseconds and then converts it with the correct unit.

Can I get the current Unix timestamp in both formats?

Yes. The page shows live current Unix timestamp values for both seconds and milliseconds, and each value can be copied separately.

What is the difference between this tool and the date calculator?

This page is focused on Unix timestamp conversion. The date calculator is for date math such as date differences, add or subtract date, and business day calculations.

Why is my converted time off by hours?

That usually happens because of a time-zone difference between UTC, your local machine, and the system where the timestamp originally came from. The timestamp may be correct even if the displayed readable time looks shifted.

How do I know whether a timestamp is in seconds or milliseconds?

A quick rule of thumb is that 10-digit Unix values are usually seconds and 13-digit values are usually milliseconds. This tool also checks the likely format automatically.

What is Unix epoch time?

Unix epoch time is the number of seconds or milliseconds that have elapsed since January 1, 1970 at 00:00:00 UTC.
