Help with making a mm/dd/yy format based off of another formula

I have a calendar that I am working with in Excel and i need to make a row that shows the mm/dd/yy for the day so that i can use that in other formulas.

This is the template I am working with

The formula that populates the automatically updating days (dependent on the calendar year) is =IF(DAY(JanSun1)=1,"",IF(AND(YEAR(JanSun1+1)=CalendarYear,MONTH(JanSun1+1)=1),JanSun1+1,""))

How can I take this formula and populate a mm/dd/yy format in a row above the days that also automatically updates like the current formula?

Thanks in advance!!

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
