Before building Cron Expression Parser, we looked at how the most commonly recommended cron tool, crontab.guru, presents a schedule.
Five run times isn't much to debug with
crontab.guru shows the next five times a cron expression will fire. That's plenty for confirming a simple daily job — but when a schedule is misbehaving in a way that only shows up every few runs, five isn't enough runway to actually spot the pattern. This tool shows ten by default.
Whose clock is it?
A comparison of crontab.guru alternatives specifically calls out timezone support as a meaningful differentiator — implying the base tool doesn't make it obvious whose clock the times are on. This tool always computes run times in your browser's own local timezone and names it explicitly on the page, so "next run" means the same thing you'd expect on your own machine.
Plain English, not just numbers
Alongside the run times, this tool describes the schedule in a sentence — "At 09:00, on Monday, Tuesday, Wednesday, Thursday, Friday" — so you can sanity-check the expression itself, not just its output.
