How can I get a words in a unselectable field?

Hello! I try to make a automation to select a leave date in a web site Like this:

First, I add a Input Dialog activity to set a leave date. then, I try to select the same date on the calendar but I don’t know how. I tried using a Find Element activity to compare the month that I inserted before and find the month on the calendar.
Anyone can I help me, please?
