Date
The date or date is a reference for a given day represented in the calendar system. Dates allow certain days to be identified. The number of days between two dates can be calculated. For example, "August 24, 2015" is ten days after "August 14, 2015" in Gregory calendar. The date of a particular event depends on the sealed time zone. Examples of air strikes against Pearl Harbor that start at 7:48 a.m. Hawaii time on 7 December 1941 occurred at 3:18 a.m. December 8 in Japan.
