💡 Did you know? The Unix epoch (timestamp 0) is January 1, 1970, 00:00:00 UTC. Unix timestamps will face the Year 2038 problem on January 19, 2038, when 32-bit signed integers overflow. Most modern systems use 64-bit integers, which won't overflow for ~292 billion years.

A Unix timestamp is the number of seconds since January 1, 1970, 00:00:00 UTC. For example, timestamp 1,000,000,000 = September 9, 2001. Our Unix Timestamp Converter converts any epoch to a readable date.
To convert minutes to seconds, multiply by 60. So 42 minutes = 2520 seconds. For hours, multiply by 3600. For days, multiply by 86400.
A leap second is an occasional one-second adjustment to UTC to keep it synchronized with Earth's rotation. The most recent was December 31, 2016, 23:59:60. Leap seconds are added irregularly by the IERS.
In Excel: =A1/86400 formats seconds as a day (use a date format to display as HH:MM:SS). =A1/3600 = hours. =A1/60 = minutes. =SECOND(A1) extracts the seconds component from a time value.
