My numbers are not newer, the generations are defined by birth date going back for many generations, these are the same (official) numbers that I have always heard and they have to be or the boomers would have been the first generation defined as a 15 year period, for one thing those born in 1945 have always been the “silent” generation of 1925 to 1945 (although not always labeled by that term0.
Boomers weren’t defined as an entire generation. A generation is considered 25 years, not 19.
Your numbers are newer, and I’m done arguing this with you. When your dates came into being and redefined the BB age range I do not know nor do I care. You go with your dates, I’ll go with mine, and all will be well.
