When in the CRON tab you a able to insert the execution time of you cron and the command.
TIME: The time is set with a numeric value to when and how often the cron job should run. The format is MINUTE HOUR DAY-OF-MONTH MONTH DAY-OF-WEEK. If we want a cronjob to run every monday at 12:00 the value would be 0 12 1 (0 minute at 12th hour at any day of month at any month at the first day of the week). A helpful tool to when setting execution time is crontab.guru.
COMMAND: Here you set the full absolute to the file you want to trigger, and commands or options you want to add. Remember that you have to use absolute paths in the command.
Below the "ADD CRON JOB" box, you see a list of all cronjobs. Both active and inactive.
