Explain a five-field cron expression and list up to ten matching times within the next 366 days. Matching uses UTC; the selected time zone changes the display only. Enter five fields in this order: minute, hour, day of month, month, and day of week. Use * for every value, commas for lists, hyphens for ranges, and / for steps. The next ten matches are found by scanning UTC minutes and formatted in the selected time zone. Supports numeric values, lists, ranges, and steps for minute, hour, day of month, month, and day of week. It does not support seconds, names, macros, or scheduler-specific extensions; matching is evaluated in UTC.

Frequently asked questions
What is the field order?
Minute, hour, day of month, month, and day of week. A seconds field is not supported.
Does this use the cron server’s time zone?
No. Matches are evaluated in UTC, then displayed in the selected time zone. A scheduler may apply different rules, especially around daylight-saving transitions.
