Is there any way to show the ""mini-calendar"" on a form for the current month - without having to click on the calendar icon?

It is for an HR app. I'd like to display the current month "mini-calendar" on screen, as the user is thinking about putting in his Starting and Ending Date of his vacation.  Currently, I have just the two date fields. They would like to see a calendar without having to click on the small calendar icon in the date field both times.
