A cron expression is five space-separated fields - minute, hour, day of month, month, and day of week - that describe a recurring schedule, used by cron itself and by countless schedulers modeled after it (CI pipelines, cloud functions, task queues). This tool parses one into a plain-English description and a list of its next actual run times, entirely in your browser.
