60 (sixty) is the natural number following 59 and preceding 61. Being three times 20, it is called threescore in older literature.
There are 60 seconds in a minute, and 60 minutes in an hour.
Greek numerals, also known as Ionic, Ionian, Milesian, or Alexandrian numerals, are a system of writing numbers using the letters of the Greek alphabet. In modern Greece, they are still used for ordinal numbers and in contexts similar to those in which Roman numerals are still used in the Western world. For ordinary cardinal numbers, however, modern Greece uses Arabic numerals.
