Granularity
The granularity is the smallest unit to use when determining whether two dates are the same; for example, if the granularity is "Year" then all dates in 1999, regardless of when they fall in 1999, will be considered the same date.
This title will be displayed on the views edit page instead of the default one. This might be useful if you have the same item twice.
