Hello @anthony.woodard91 welcome to the community!
Dates are numbers in milliseconds…. this is the reason why it is meticulous to manage them. Every milllionth second that passes is a different number. What we see is a formatted representation to understand it. And this format varies as well know (month first day next, am/pm, with time or not, etc etc)
One simple way to manage choosing dates as month/day is :round down to date which brings that number to the equivalent of 00:00 of that day
