What if the system of year reckoning that we use today were transposed a few years one way or the other?
After thinking about how we tend to group significant events into decades, and look back on each decade as having a specific character as a generation, I wonder how our perception of events would be different.
For example, what if the dates of WWII were 1935 to 1941?
What if the counter-culture movement dominated the 50s?
Or what if the new Millennium were dawning right now, or dawned in 1990?
