Step-by-Step Guide

1

Prepare your timestamps

Gather the epoch timestamps or dates you want to convert. You can paste a list of Unix timestamps (seconds or milliseconds since 1970-01-01), or ISO date strings, or any common date format.

2

Paste into the converter

Paste your list into the input area, one timestamp per line. The tool automatically detects whether each line is an epoch timestamp or a date string.

3

Choose your conversion direction

Select "Epoch to Date" to convert Unix timestamps to human-readable dates, or "Date to Epoch" to convert dates to Unix time. You can also choose the output format.

4

Copy the results

The converted timestamps appear instantly. Click "Copy All" to copy the entire results column, or copy individual entries. Results include both the original input and the converted output for easy comparison.

Frequently Asked Questions

What is epoch time?
Epoch time (Unix timestamp) is the number of seconds or milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is a standard way to represent time in computing systems.
Seconds or milliseconds?
The tool auto-detects: 10-digit numbers are treated as seconds, 13-digit numbers as milliseconds. You can also manually select which unit to use for ambiguous inputs.
Can I convert timezones?
Yes. All epoch conversions use UTC as the base. You can display results in your local timezone or specify a different timezone offset.
