Frequently asked questions
What timezone do the next run times use?
Your browser's local timezone. A real cron daemon runs in whatever timezone the host system (or scheduler config) is set to — check that separately when scheduling on a server.
What if day-of-month and day-of-week are both restricted?
Standard cron treats this as OR, not AND — the job runs when either field matches. This tool follows that same convention.
Is my expression uploaded when I use this tool?
No. Parsing and calculating run times happens instantly in your browser — nothing is sent to a server.
