Convert Unix timestamps to dates and dates to timestamps. Live clock included.
A Unix timestamp counts the number of seconds since January 1, 1970 00:00:00 UTC (the "Unix epoch"). It is used universally in programming, databases, APIs, and log files because it is timezone-independent and easy to compare mathematically.
Unix timestamps in seconds are 10 digits (e.g., 1712434800). JavaScript and Java use milliseconds (13 digits, e.g., 1712434800000). This tool auto-detects which format you enter.
Systems using 32-bit signed integers to store timestamps will overflow on January 19, 2038. Most modern systems use 64-bit integers, which won't overflow for another 292 billion years.
