Convert between seconds, milliseconds, ISO 8601 and readable dates. Auto-detects your timezone.
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970 (UTC). It's widely used in programming, databases, and APIs for representing time as a single number. This tool converts between Unix timestamps and human-readable date formats.
Debugging API responses that use Unix timestamps. Working with database timestamps in various formats. Converting timestamps for log analysis. Understanding timestamp formats when learning programming.
Enter a Unix timestamp in the input field to convert it to a human-readable date. The tool automatically detects if it's in seconds or milliseconds. To convert a date to a timestamp, enter the date and time and get the timestamp result. You can also see the current timestamp updated live.
A Unix timestamp is the number of seconds (or milliseconds) that have passed since January 1, 1970 00:00:00 UTC (the Unix Epoch). It's a universal way to represent time as a single number, avoiding timezone confusion.
10-digit timestamps represent seconds (e.g., 1700000000). 13-digit timestamps represent milliseconds (e.g., 1700000000000). JavaScript uses milliseconds, while most backend languages and databases use seconds.
No, Unix timestamps are always in UTC (Coordinated Universal Time). When you convert a timestamp to a local time, your timezone offset is applied. The same timestamp represents the same moment everywhere on Earth.
The Year 2038 problem is when 32-bit signed Unix timestamps will overflow on January 19, 2038 at 03:14:07 UTC. Most modern systems use 64-bit timestamps which won't have this problem for billions of years.
