Limit Dates in the Calendar Picker

My understanding is that this will allow the calendar to only show the month that I chose - April.

I've set limits in the dates, however it isn't' working. The Arrival Date and Departure Date both start at January.

I've checked your form. The Arrival Date and Departure Date fields showing January because you've set the default date as current date.

If you want to allow only the April month, in the Limit section set the Start & End Date to April. And also change the Default value to Custom and set it as April 1st.

Feel free to revert back if you need any further assistance.

Thank you
