Gen Y starts somwhere in the early 80s, the specific start is irrelevant since they are cuspers anyways
1980-The last to be too young to graduate college in four years before 9/11 as well as the first to be teenagers in this millennium. They were also the first to be under full adulthood age (20 and higher) before the world population hit 6 billion in late 99.
1981-The last to graduate high school before world population hit 6 billion in late 99.
1982-The first to graduate high school in this millennium and the first to be under full adulthood (age 20 and up) before 9/11
The best start dates for X are these. This ranges from 1960-1965 with 1960 and 1965 as the most common start dates. First one appeals for me, but second one is the only other reasonable one. 1961-1964 should be in the same generation as 1960 as I dont see a difference between 1960-1964.
1960-The first to be born after the year Hawaii became the 50th state of the US and after the year of NASA’s first mission, the Mercury Program.
1965-The first to be too young for primary school before Apollo 11 and the invention of the internet in 1969.
Other than what I listed above, I can agree with how you defined the generations
