Quartz cron examples

Control supports custom Quartz cron expressions for schedules. In the management UI, the expression is entered in this format:

seconds minutes hours day-of-month month day-of-week

Field overview

Field	Position	Typical values	Example
Seconds	1	0, 15, 0/30	0
Minutes	2	0, 5, 0/5	0/15
Hours	3	0, 9, 8-17	9
Day of month	4	*, 1, 15, ?	?
Month	5	*, 1, 1-6, JAN	*
Day of week	6	*, MON-FRI, SUN, ?	MON-FRI

Important syntax rules

• Use * to mean "every value" in that field.
• Use ? in either day-of-month or day-of-week when that field is intentionally not used.
• Use - for ranges, for example 8-17.
• Use / for intervals, for example 0/15.
• Use MON, TUE, WED, THU, FRI, SAT, and SUN for weekdays when that is easier to read.

Note

When a schedule is based on weekday logic, it is usually clearer to use ? for day-of-month.

Example schedule object

{
  "id": "20260320_101500",
  "display_name": "Weekday synchronization",
  "type": "Pipes",
  "schedule": "0 0/15 8-17 ? * MON-FRI",
  "run_on_start": false,
  "params": {
    "pipes": [
      "20260320_101500_pipe"
    ]
  }
}

Legacy aliases

Some existing configurations may still use aliases instead of explicit Quartz cron expressions, for example:

• EVERY_5_MINUTES
• EVERY_30_MINUTES
• EVERY_HOUR
• EVERYDAY_AT_MIDNIGHT

For new configurations, prefer explicit Quartz cron expressions because they are easier to review and adjust.
