This add-on provides precise control over which dates are available for selection in date picker fields within forms. It is designed for site builders and administrators who need to enforce date-specific rules, such as preventing future selections for incident reports or defining booking windows for events.

• Minimum and Maximum Date Ranges: Define the earliest and latest selectable dates. You can set these to a fixed calendar date, base them on the current date, or link them dynamically to a date selected in another field on the form.
• Day of the Week Restrictions: Specify exactly which days of the week are available for selection. This is useful for creating forms that only accept submissions on business days or specific weekend dates.
• Date Exceptions: Override your standard rules for specific calendar dates. Make a normally blocked date available, or disable a date that would typically be selectable, allowing for holidays or special closures.
• Linked Date Fields: Create dependencies between date fields. For example, the date chosen in a 'Start Date' field can automatically set the minimum allowable date in a separate 'End Date' field, ensuring logical sequences.
• Automatic Validation: Ensures date rules are enforced whether a user selects from the picker or types a date manually. Validation occurs both in the browser for immediate feedback and on the server for security.
