In above screenshot, i am selecting Month through drop down in cell A48, i want to auto fill dates in cell B51:AF51. For example, if i select May month then dates 1 to 31 and for June dates 1 to 30 should be autofilled.

In b51,

=if(month($a48)=month(date($a47, month($a48), column(a:a))), date($a47, month($a48), column(a:a)), text(,))

Fill right an additional 30 cells.
