[Quartz] Cron Trigger Pattern

Quartz CronTrigger uses cron expressions. But it is not equal to UNIX cron tool.

Quartz CronTrigger uses not 5 fields expression like Unix cron, but 6 or 7 fields expression.

It can define Seconds and Year(Optional).

Expression

Field name	Mandatory	Allowed Values	Allowed Sepecial Characters
Seconds	true	0~59	, - * /
Minutes	true	0~59	, - * /
Hours	true	0~23	, - * /
Day of month	true	1~31	, - * / ? L W
Month	true	1-12 or JAN-DEC	, - * /
Day of week	true	1-7 or SUN-SAT	, - * / ? L #

Special Characters

Character	Name	Description
*	All values	Select all values within a field
?	No specific value
-	Range	Sepecify ranges
,	Add	Add values
/	Increment	Specify increments
L	Last	Specify last day of months or last day of weeks
W	Weekday	Specify the weekday(Monday-Friday). As an example, if you were to specify “15W” as the value for the day-of-month field, the meaning is: “the nearest weekday to the 15th of the month”.
LW	Last weekday	Specify the last weekday of month
#	Select week	used to specify “the nth” XXX day of the month. For example, the value of “6#3” in the day-of-week field means “the third Friday of the month” (day 6 = Friday and “#3” = the 3rd one in the month). Other examples: “2#1” = the first Monday of the month and “4#5” = the fifth Wednesday of the month. Note that if you specify “#5” and there is not 5 of the given day-of-week in the month, then no firing will occur that month
