Remarks

Operators:

There are several ways of specifying multiple date/time values in a field:

  • The comma (',') operator specifies a list of values, for example: "1,3,4,7,8"
  • The dash ('-') operator specifies a range of values, for example: "1-6", which is equivalent to "1,2,3,4,5,6"
  • The asterisk ('*') operator specifies all possible values for a field. For example, an asterisk in the hour time field would be equivalent to 'every hour' (subject to matching other specified fields).
  • The slash ('/') operator (called "step"), which can be used to skip a given number of values. For example, "*/3" in the hour time field is equivalent to "0,3,6,9,12,15,18,21". So "*" specifies 'every hour' but the "*/3" means only those hours divisible by 3.

Fields:

+---------------- minute (0 - 59)
|  +------------- hour (0 - 23)
|  |  +---------- day of month (1 - 31)
|  |  |  +------- month (1 - 12)
|  |  |  |  +---- day of week (0 - 7) (Sunday=0 or 7)
|  |  |  |  |
*  *  *  *  *

Each of the patterns from the first five fields may be either * (an asterisk), which matches all legal values, or a list of elements separated by commas.
