Function to conver a Serial To Date

hy, i need to convert a given number to a date via function…

what i mean is lets say i give a number 8 to a function and it returns the correct date from 8 days from today(a. la. 29/12/20012). as that seems simple enough i also need it to work when the number is 2000 with correct month etc…

im quite sure that many ppl have dont this. so before i try to re-invent the wheel i thought id just ask - cant find it on google :frowning: - though maybe im just no looking for it the right way :wink:
