Age, whether of people or wine, can be a sensitive matter where precision is assumed even when not present. This video demonstrates two very different ways to enable a form to determine age. The first method is easy and  plenty "good enough" for most uses. The second, well, it's perfect and will determine age accurately even if the person was born, or the wine harvested, on a February 29th in the last century. It is for people who insist on accuracy.And, again, once done, the work can be copied for any use.
