⏰ Cron Visual Editor

About the Cron Visual Editor

Cron is the standard Unix and Linux task scheduler. It runs commands or scripts automatically at specified times and intervals without any manual intervention. Cron jobs are defined in a file called a crontab (cron table), where each line describes one scheduled task.

Crontab syntax

Each cron entry consists of five time fields followed by the command to execute:

MIN  HOUR  DOM  MON  DOW  COMMAND

• MIN — minute of the hour (0–59)
• HOUR — hour of the day (0–23, where 0 = midnight)
• DOM — day of the month (1–31)
• MON — month of the year (1–12)
• DOW — day of the week (0–6, where 0 = Sunday)

Each field accepts * (any value), */n (every n units), n-m (a range), or a,b,c (a list).

Special shortcuts

Instead of five fields, you can use shorthand strings: @hourly, @daily, @weekly, @monthly, @yearly, and @reboot (runs once at system startup).

Common schedule examples

• */15 * * * * — every 15 minutes
• 0 2 * * * — every day at 2:00 AM
• 0 9 * * 1-5 — weekdays at 9:00 AM
• 0 0 1 * * — on the first day of every month at midnight

How to use this tool

• Import an existing crontab by pasting its full content — the tool parses each line into the visual table, preserving comments and disabled entries.
• Build Entry to interactively configure each field with validation and a live human-readable schedule preview.
• Click any cell in the table to edit it directly. Toggle the checkbox to enable or disable an entry without deleting it.
• Download exports a ready-to-use crontab file. Document exports a Markdown or Excel table documenting every scheduled job.
