Paste a five-field cron expression and get a plain-English description plus a preview of the next run times. Cron syntax is compact but easy to misread, and a wrong field can mean a job fires every minute instead of once a day. This parser explains what each part of your schedule means (minute, hour, day of month, month and day of week) and then computes the upcoming fire times so you can confirm the schedule matches your intent before deploying it. It supports lists, ranges, steps and wildcards. Enter your expression to see the explanation and the next several runs update live. All parsing happens in your browser, so nothing about your jobs or infrastructure is sent anywhere.
