Cron syntax

cron(minutes hours day-of-month month day-of-week year)

Wildcards

• The , (comma) wildcard includes additional values. In the Month field, JAN,FEB,MAR includes January, February, and March.
• The - (dash) wildcard specifies ranges. In the Day field, 1-15 includes days 1 through 15 of the specified month.
• The * (asterisk) wildcard includes all values in the field. In the Hours field, * includes every hour. You can't use * in both the Day-of-month and Day-of-week fields. If you use it in one, you must use ? in the other.
• The / (slash) wildcard specifies increments. In the Minutes field, you could enter 1/10 to specify every tenth minute, starting from the first minute of the hour (for example, the 11th, 21st, and 31st minute, and so on).
• The ? (question mark) wildcard specifies any. In the Day-of-month field you could enter 7 and if any day of the week was acceptable, you could enter ? in the Day-of-week field.
• The L wildcard in the Day-of-month or Day-of-week fields specifies the last day of the month or week.
• The W wildcard in the Day-of-month field specifies a weekday. In the Day-of-month field, 3W specifies the weekday closest to the third day of the month.
• The # wildcard in the Day-of-week field specifies a certain instance of the specified day of the week within a month. For example, 3#2 would be the second Tuesday of the month: the 3 refers to Tuesday because it is the third day of each week, and the 2 refers to the second day of that type within the month.

📘

Note

If you use a '#' character, you can define only one expression in the day-of-week field.

For example, "3#1,6#3" is not valid because it is interpreted as two expressions.

You can also create a 1 time rule that would trigger on a specific time.

{
  "rule_type" : "one_time",
  "date_and_time" "at(2025-11-08T12:00:00)"
  "timezone": "Asia/Jakarta",
}
