Minute

The minute is a unit of time defined as equal to 60 seconds.

One hour contains 60 minutes.

Although not an unit in the International System of Units (SI), the minute is accepted for use in the SI. The SI symbol for minutes is min (without a dot). The prime symbol ′ is also sometimes used informally to denote minutes.

In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds; there is also a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system.
