4 years on mine..................2nd at honey show
I only use the bbe date as my lot No ie 12 07 18, I trace this from jar to bucket / apiary and harvest day as kept in my records.
I had to add a Lot No to comply with the honey show rules (commercial class) and after arguing I didnt need to but as they were the rules I had too I added a 4 digit ficticious number in biro on the tamper label and .............got 2nd place. Also got a note on my jars saying strictly speaking it should have my name on the label too.............despite it having my trading Co name and full postal address.
