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.
The government does not define generations by 25 year periods and the category that we call boomers has always been 1946 to 1964, the silent generation is 1925 to 1945, the GI generation is 1901 to 1924 etc.
