The Cron Equivalent on Windows

Windows does not have cron. The native equivalent is Task Scheduler, which you can drive from the command line with schtasks. If you need real crontab syntax, run it inside WSL.

Native: schtasks

To run a script every 15 minutes: schtasks /create /tn "MyJob" /tr "C:\scripts\job.bat" /sc minute /mo 15. Use /sc daily /st 09:00 for a daily 9 AM job. Manage tasks in the Task Scheduler GUI (taskschd.msc).

Real cron via WSL

Install WSL, then inside your Linux distro: sudo service cron start and crontab -e works normally. Note WSL's cron only runs while the WSL instance is running.

Mapping intervals

crontab */15 * * * * maps to /sc minute /mo 15; 0 * * * * to /sc hourly; 0 0 * * 0 (weekly Sunday) to /sc weekly /d SUN.
