Unix Timestamp Converter
Turn Unix epoch timestamps into readable dates — and dates back into timestamps. Works in both directions.
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the “Unix epoch”). It is how computers store points in time: one number, no time zones to misinterpret. Many systems and APIs also use milliseconds (13 digits instead of 10) — this tool detects which one you pasted automatically.
Frequently asked questions
Why does the same timestamp show a different time for my friend?
Timestamps are absolute, but the display is converted to your local time zone. The tool shows both your local time and UTC so you can verify either.
What happens in 2038?
Older 32-bit systems can only count up to January 19, 2038 (the “Y2K38 problem”). Modern 64-bit systems — including every phone and computer sold in the last decade — are unaffected for billions of years.
Can I convert a date like 1970-01-01?
Yes — as long as it is after the epoch. Set the exact date and time in the third box and you will get the precise timestamp, including seconds.
