4	* Day of week field. Allows: * / , - ? L #
5	*
6	* Days of the week can be represented as a number 0-7 (0\|7 = Sunday)
7	* or as a three letter string: SUN, MON, TUE, WED, THU, FRI, SAT.
8	*
9	* 'L' stands for "last". It allows you to specify constructs such as
10	* "the last Friday" of a given month.
11	*
12	* '#' is allowed for the day-of-week field, and must be followed by a
13	* number between one and five. It allows you to specify constructs such as
14	* "the second Friday" of a given month.
