To me, generations don’t make sense. I changed my mind on how I see them as I can never understand how people who are ten years apart can be in the same generation. So a more realistic way of looking at generations is by shortening them to a maximum of 4-6 years called sub-gens. However, there are some years that wouldn’t necessarily fit into a single sub-gen. These years would be known as hybrid years as they tend to be very unique from the other years by being a border between the two sub-gens. Another thing I changed my mind on is this classification would not go by the class you are in and what year your graduating because that tends to be very difficult to define universally as many countries and even states have different cutoffs for grades. Instead it would go simply by years from January to December.
