What is Parse Cron Expression?

Parse Cron Expression is a free online tool that translates cron expressions into plain English and shows the next 5 scheduled execution times. Supports standard 5-field cron (minute, hour, day, month, weekday).

How It Works

The parser splits the cron expression into its 5 fields and applies plain-English rules for each special character: * (any), / (every N), - (range), and , (list). Next execution times are computed by stepping through minutes until all 5 fields match.

How to Use

  1. 1

    Enter a cron expression

    Type a cron expression (e.g. "0 9 * * 1-5") into the input field.

  2. 2

    Parse

    The tool instantly translates the expression into plain English — e.g. "Every weekday at 9:00 AM".

  3. 3

    View next run times

    See a list of the next 10 scheduled execution times based on the expression.

  4. 4

    Use the builder (optional)

    Use the visual cron builder to construct an expression by selecting schedule parameters without memorizing syntax.
