Frequently Asked Questions
What is a cron expression? ▼
A cron expression is a string of 5 fields (minute hour day-of-month month day-of-week) used to schedule recurring tasks on Unix-like systems. Each field specifies when the task should run.
How do I read a cron expression? ▼
Read left to right: minute (0–59), hour (0–23), day of month (1–31), month (1–12), day of week (0–6, where 0 is Sunday). Asterisks mean "every", slashes define steps (*/5 = every 5), and hyphens define ranges (1-5 = Monday through Friday).
What does '0 9 * * 1-5' mean? ▼
It means "At 09:00, Monday through Friday". The 0 is the minute, 9 is the hour, asterisks mean every day and every month, and 1-5 means Monday through Friday.
