The Cron Expression Validator is a high-precision tool designed to ensure scheduling accuracy for automated tasks. It supports both the standard 5-field cron format and the extended 6-field format (including seconds). By using validate_cron_expression, you can instantly detect syntax errors or range violations, such as an invalid minute value. For complex scheduling needs, calculate_next_execution computes the exact next occurrence of a schedule from any given ISO 8601 timestamp. Additionally, parse_cron_components allows for deep inspection of each field's pattern, making it easy to debug complex cron strings containing wildcards, ranges, or steps.

3 tools expose this connector's capabilities to your AI agent.

parse_cron_components

Deconstructs a cron expression into its individual parts to allow for detailed inspection

validate_cron_expression

Checks if a provided string is a syntactically correct cron expression and if all values fall within their permitted numerical ranges

calculate_next_execution

Computes the exact next occurrence of a cron schedule after a specific point in time

Is this cron expression valid: '*/5 0 * * *'?

Yes, the expression is valid. It is configured to run every 5 minutes during the midnight hour.

When is the next time '0 12 * * *' will run after 2024-01-01T00:00:00Z?

The next execution is scheduled for 2024-01-01T12:00:00Z.

Check if '61 * * * *' is a valid cron expression.

The expression is invalid because the minutes field contains '61', which exceeds the maximum allowed value of 59.

Yes, by setting the `isExtended` parameter to true in tools like `validate_cron_expression`, you can validate and calculate schedules that include seconds.
