FAQ

What is a cron expression?

A cron expression is a string of 5 (or 6) fields that defines a schedule. The fields are: minute, hour, day of month, month, and day of week. Special characters like *, /, and - define patterns.

What does each field mean?

Field 1: Minute (0-59), Field 2: Hour (0-23), Field 3: Day of month (1-31), Field 4: Month (1-12), Field 5: Day of week (0-7, where 0 and 7 are Sunday).

What does */15 mean?

*/15 means "every 15 units". So */15 in the minute field means every 15 minutes (0, 15, 30, 45).

How do I use the visual builder?

Switch to Builder mode using the toggle. Select values from the dropdowns for each cron field (minute, hour, day, month, weekday). The expression updates automatically.
