No matter your background or use case, the Cron Expression Parser delivers fast, accurate results without the overhead of heavyweight software or complex setup.
Here are detailed answers to the most common questions about the Cron Expression Parser:
A cron expression is a string of 5 fields that define a recurring schedule: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, where 0=Sunday). It's used in Unix cron jobs, CI/CD pipelines, cloud schedulers, and application task runners.
The asterisk (*) is a wildcard meaning 'every value'. For example, * in the hour field means 'every hour'. 0 9 * * * means 'at 9:00 every day of every month'.
Use */15 in the minute field: */15 * * * *. The /n syntax means 'every n units' — so */15 means every 15 minutes starting from minute 0.
Both can restrict when a job runs. If you specify both (non-wildcard), most cron implementations run the job when EITHER condition is true (OR logic), not both (AND logic). Use * for one field when you only want to restrict by the other.
Standard Unix cron uses 5 fields (no seconds). Some systems like Spring/Quartz use 6 or 7 fields including seconds. This parser follows the standard 5-field format.
Use 1-5 in the weekday field: 0 9 * * 1-5 runs at 9am Monday through Friday. 0 means Sunday and 6 means Saturday.
