Frequently Asked Questions

Get answers to common questions about cron jobs, scheduling, and using our cron expression generator.

A cron job is a scheduled task that runs automatically at specified times on Unix-like systems. Cron jobs use cron expressions (like "0 9 * * 1-5") to define when they should execute, making them perfect for automation, backups, and recurring tasks.
Cron expressions have 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7). For example, "30 14 * * 1-5" means run at 2:30 PM on weekdays. Use our generator to see exactly when your cron will run.
Standard cron jobs can run as frequently as once per minute. For more frequent execution, you need extended cron formats or specialized schedulers. Our tool supports both standard 5-field and extended 6-field cron expressions.
Cron jobs typically run in the server's local timezone. Some systems support timezone-specific cron formats. Our tool lets you preview execution times in different timezones to help you schedule jobs correctly.
Popular examples include: "0 0 * * *" (daily at midnight), "*/15 * * * *" (every 15 minutes), "0 9 * * 1-5" (weekdays at 9 AM), and "0 0 1 * *" (first day of each month). Browse our 316+ presets for more examples.
Common issues include: incorrect cron syntax, missing file permissions, wrong file paths, minimal environment variables, or cron daemon not running. Use our validator to check your syntax and see the human-readable description of your schedule.

Daily Cron Patterns Explained

Understanding Daily Cron Syntax

A daily cron expression uses the format 0 H * * * where H is the hour (0-23). The first field (minute) is typically set to 0, and the last three fields (day of month, month, day of week) use wildcards to run every day.

0 0 * * * - Run at midnight (hour 0)
0 14 * * * - Run at 2:00 PM (hour 14)
30 9 * * * - Run at 9:30 AM (minute 30, hour 9)

Combining Daily with Day-of-Week

Restrict daily jobs to specific days of the week for business-hour scheduling:

0 9 * * 1-5 - Weekdays only at 9 AM
0 8 * * 0,6 - Weekends only at 8 AM
0 17 * * 1,3,5 - Mon/Wed/Fri at 5 PM

DST and Time Zone Considerations

Important notes for daily scheduled jobs:

  • During DST spring-forward, jobs scheduled at 2 AM may be skipped entirely
  • During DST fall-back, jobs scheduled at 1 AM may run twice
  • Use UTC for critical jobs to avoid DST issues altogether
  • Avoid scheduling important jobs between 1 AM and 3 AM in DST-affected zones
