    Thank you for contacting us.

    1) To calculate the number of days:

    - Use the Date Picker fields.

    - Calculate the dates difference using a Form Calculation widget field.

    2) To get a day of the week:

    - Use the Form Calculation fields.

    - Check In Date should receive a date with a dateString function (see this guide).

    - You will need to add an 'Update / Calculate Field' condition for each day.

    You can clone it to your account to check the backend.
