About this tool
A cron expression packs a schedule into five fields: minute, hour, day of month, month, and day of week. Reading one at a glance is hard, especially with ranges, steps, and lists mixed together. This tool takes an expression like 0 9 * * 1-5 and turns it into a sentence you can actually read, plus a list of its next five run times in your local time zone.
Everything runs in your browser. The expression you type never leaves your machine, so you can check a schedule from a private deployment config or a cron job you’d rather not paste into a public site.
Common uses: verifying a schedule before you commit it to a crontab or CI config, double-checking a @daily or @hourly macro, or figuring out when a colleague’s job actually fires. See the crontab(5) man page for the full field syntax and the Wikipedia article on cron for background on the format’s history.
