Generations usually last 18-20 years and remembering the first year of a decade isn't always required to be a part of that generation. I have noticed that while the term for Baby Boomer requires that definition, I've seen that your definitions of gen x, millennial, and gen z don't. Gen X is from 1961-1981 or 1964-1984, as most people at this age remember the Fall of the Berlin Wall, the end of the Cold War, the AIDS Crisis, and the start of MTV and music videos. Yet you put it on 1965-1980 which is only 15 years. Millennial is from 1980-2000 because most people at that age remember 9/11 and the War in Iraq, as well as Obama's election, the Great Recession, and the rise of internet. Yet you put that it was at 1981-1996. I myself don't want to be a part of gen z as a 1999 born kid because I can remember all those. And my brothers born in 2006 and 2009 can't. Not to mention they are ignorant and bigoted and I don't want to have to share the same generation as them. Speaking of gen z, I've noticed that you have added it as 1997 and onward when it is supposed to be post 2000-2001. I find this unfair as most people born in the late 90's can remember millennial events and not just Trump's election, growing up with tablets, terrorism after 9/11 and the Iraq War, Brexit, and social media. 

You said you would be open to change, so please consider this. I would really like to have previous terms back. Especially the 1980-2000 dates as millennial.
