Convert Unix timestamps to human-readable dates and back. Supports multiple timezones.
Enter Unix timestamp (10-digit seconds or 13-digit milliseconds)
Select a date and time to get its Unix timestamp
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970 (UTC). It's a simple, timezone-independent way to represent time and is widely used in programming and databases.
Because timestamps are just numbers, converting them to human-readable dates requires knowing the timezone. Our converter shows the date in your local timezone and lets you convert dates back to timestamps too.
A: Use the live converter above — it shows the current timestamp in real time.
A: Unix timestamps are in seconds, but many systems (like JavaScript) use milliseconds — just multiply or divide by 1000.
A: 32-bit systems face the "Year 2038 problem" where timestamps overflow. Most modern systems use 64-bit timestamps, which are safe for billions of years.
