Below I attached a Excel file that contains the cell that will date which is based on the spin button value. The date will start the first date of 2023 and for every spin button value increase, the date will increase by one day. You also can resize that spin button according to your need.
You obviously can increase the incremental value of the spin button for each spin.
If you need any customizable data format, please let me know. and don't forget to attach a sample file that contains your data.
