Block users from selecting specific dates, such as public holidays, company off-days, or other unavailable dates. This is especially useful for booking forms or appointment scheduling.

Set a date range to restrict users to only select dates within a specific timeframe. For instance, you can limit users to choose dates from January 1, 2025, to December 31, 2025.
Combine multiple rules for more complex restrictions, such as excluding certain days of the week, blocking specific dates, and limiting the date range—all customizable through a shortcode for each form.
By implementing date restrictions in your WPForms, you enhance the user experience. Users will only see and be able to select valid and relevant dates, reducing confusion and potential errors.
