The serial number does NOT contain the date of manufacture on a Benelli (or any Italian-made firearm). You need to look for some "proof-markings," likely along the left side of the barrel beneath where it says, "Benelli Armi SPA Urbino Made in Italy." One of these markings will have two letters enclosed in a box. That is your date code.
