Note that this only occurred because you left off the century. Further down on the help page it says:
If you want to specify a date more than five years in the future, simply be sure to fill in the entire century rather than just the last two digits of the year, for example 7/2/2024 .
I guess I should probably change that to something like 7/2/2097 so that it will be a correct example for a long time.
By the way, this default century behavior is a bit different than it used to be. It used to default to the nearest 50 years. But I changed it because I think dates in the past are much more commonly used than dates in the future.
