Cron Expression Parser

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.

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).

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

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.
