javascript — Ограничение выбора даты / времени

Я использую плагин для контактной формы 7 datepicker, который отлично работает, но я стараюсь ограничить его значения: https://wordpress.org/plugins/contact-form-7-datepicker/.

Я хочу, чтобы пользователи могли использовать средство выбора даты в моей контактной форме 7 форм бронирования, но я хочу, чтобы они могли выбирать только день, который наступает не ранее, чем за 1 день и за 1 час. Поэтому, если я попытаюсь выбрать сегодняшнюю дату и сегодняшнее время, появится всплывающее предупреждение о том, что это слишком рано. Это должно быть 25 часов в ближайшее время. Как бы я начал это с приведенного ниже кода плагина:
