Crontab generator is a tool for quick creation and visual verification of cron job schedules. It allows you to transform complex five-part expressions into a readable human language description.

Enter the expression into the text field or use popular examples. The tool will automatically highlight the active part (minutes, hours, etc.) and show 5 upcoming executions in UTC.

• * * * * * — every minute.
• 0 0 * * 1 — every Monday at midnight.
• */15 9-17 * * 1-5 — every 15 minutes during business hours on weekdays.

We use the standard cron syntax (5 fields). Specific extensions (e.g., for Quartz or Jenkins with 6-7 fields) may not be supported or may be interpreted differently.

• What does the asterisk (*) mean? It means 'every' (every minute, hour, etc.).
• How does the step (/) work? For example, */5 in the minutes field means 'every 5 minutes'.
• Why 'OR' between day of month and day of week? This is a specific feature of the cron standard: if both fields are specified, the task runs when either of these conditions matches.
