This tool generates standard 5-field cron format (minute hour day month weekday), compatible with Linux crontab, Kubernetes CronJob, Apache Airflow, and other major scheduling systems. Supports exact values, wildcards (*), ranges (1-5), steps (*/5), lists (1,3,5), and all standard cron syntax.
Common examples: every 5 minutes (*/5 * * * *), every hour (0 * * * *), daily at 2 AM (0 2 * * *), every Monday at 9 AM (0 9 * * 1), 1st of each month at midnight (0 0 1 * *), weekdays at noon (0 12 * * 1-5). You can use the preset buttons to quickly generate these common expressions.
Standard cron expressions execute based on the server's local timezone (usually UTC). This tool does not handle timezone conversion — the generated expression will run according to the target system's timezone configuration.
No. This tool runs entirely in your browser — all cron expression generation and explanation happens locally on your device, no internet connection needed.
The 5-field format (minute hour day month weekday) is the most common and widely compatible. The 6-field format (second minute hour day month weekday) adds second-level precision. This tool generates 5-field format; add a leading second field if needed.
