Page "Minute" Paragraph 3

In old astronomical texts, minute can also mean a unit of time equal to of a day ( 24 usual minutes ).

These minutes correspond to the Latin diei scrupulis, and used to express periods of planetary motions.

For example, Kepler in Harmonices Mundi gives Saturn's year as 10759D12 ', that is 10759 ( Earth ) days, 4 hours, and 48 ( usual ) minutes ( roughly 29. 5 years ).
