What is CRON ?
Cron is a time-based job scheduler in Unix-like operating systems (including Linux and macOS). It allows users to schedule tasks—known as cron jobs—to run automatically at specific intervals, dates, or times. Instead of a human manually typing a command every day, the crond (Cron Daemon) stays awake in the background, checking the clock every minute to see if a scheduled task is due to be executed.
Why using CRON visualizer ?
While Cron is powerful, it is famously difficult to read at a glance. A single typo (like putting a * in the wrong place) can result in a script running every second instead of every day, which can crash a server.
| Frequency | Expression | Description |
|---|---|---|
| Cron at midnight | "0 0 * * *" | The classic "Daily maintenance" time for starting clean the day. |
| Cron at 3:00 AM | "0 3 * * *" | "Daily maintenance" but maybe at a better time for your own stuff. |
| Cron on Monday | "0 0 * * 1" | Runs a cronjob at midnight, the first day of the week, to start fresh. |
| Cron the 1st | "0 0 1 * *" | Runs a cronjob at midnight, the first day of the month. For something like Invoices, etc.... |
