Everything you need to know about cron expressions
A cron expression is a string of five or six fields separated by spaces that represents a schedule. The fields specify minute, hour, day of month, month, and day of week. For example, 0 9 * * 1-5 means "every weekday at 9:00 AM". Cron expressions are used by Unix-like systems, task schedulers, and CI/CD tools to automate recurring tasks.
Simply type your cron expression directly into the input field at the top, use the quick presets for common schedules, or build your schedule using the Simple or Advanced tabs. CronForge instantly shows you a human-readable description and calculates the next scheduled run times in your timezone.
The asterisk (*) is a wildcard that means "every" or "any value". For example, * in the minute field means "every minute", and * in the day-of-week field means "every day of the week". You can combine it with other operators like */5 to mean "every 5 units".
Standard Unix cron uses 5 fields: minute, hour, day of month, month, and day of week. Some systems like Quartz scheduler (used in Java) and Spring add a 6th field for seconds at the beginning. CronForge supports both formats—just check "Include seconds field" to switch to 6-field mode.
Use 1-5 in the day-of-week field (where 1=Monday and 5=Friday). For example, 0 9 * * 1-5 runs at 9 AM every Monday through Friday. You can also use MON-FRI on some systems.
