RANDBETWEEN then generates a number that falls between these two date values.
RANDBETWEEN recalculates each time a worksheet is opened or changed.
Random date between two dates
To generate random dates between two dates, you can use the RANDBETWEEN function, together with the DATE function. In the example shown, the formula in B5 is: =RANDBETWEEN(DATE(2016,1,1),DATE(2016,12,31)) This formula is then copied down from B5 to B11. The result is random dates between Jan 1, 2016 and Dec 31, 2016 (random dates in the year 2016).
