Convert between Unix timestamps and human-readable dates.
About this tool
Converts between Unix timestamps and human-readable dates, in both your local timezone and UTC — useful when debugging logs, APIs, or databases that store times as epoch seconds or milliseconds.
Frequently asked questions
Does this tool handle milliseconds or seconds?
Both — it detects which one you've entered based on the number's magnitude (timestamps in milliseconds are about 1000x larger than the same moment in seconds) and converts accordingly.
Why does the same timestamp show a different time for me than for someone else?
The "Local" result reflects your browser's timezone setting, which varies by location — the UTC result is what's actually timezone-independent and comparable across users.
