  • Format

    A cron expression is a string comprised of 6 or 7 fields separated by white space. Fields can contain any of the allowed values, along with various combinations of the allowed special characters for that field. The fields are as follows:

    Field Name	Mandatory?	Allowed Values	Allowed Special Characters
    Seconds	YES	0-59	, – * /
    Minutes	YES	0-59	, – * /
    Hours	YES	0-23	, – * /
    Day of month	YES	1-31	, – * ? / L W C
    Month	YES	1-12 or JAN-DEC	, – * /
    Day of week	YES	1-7 or SUN-SAT	, – * ? / L C #
    Year	NO	empty, 1970-2099	, – * /

    So cron expressions can be as simple as this: * * * * ? *
    or more complex, like this: 0 0/5 14,18,3-39,52 ? JAN,MAR,SEP MON-FRI 2002-2010
