Cron Collider

Paste a crontab and see when every job actually fires across the week, where jobs pile up on the same minute, and which people-facing jobs ping during quiet hours. One click spreads the pileup onto quieter minutes.

Your crontab 0 jobs

One job per line: five fields (min hour dom mon dow) or a macro like @hourly, then a job name. Lines starting with # are ignored.

A job is people-facing when its name mentions notify, email, slack, sms, text, remind, digest, alert, ping, or report. Only those count against quiet hours; backups at 3 AM are fine.
