    What a year!

    This may be a repeat puzzle but if it has, it's been a long while...
    Only once in American history has there been a decade in which four of the years were prime numbers. Can you find it?

    Perhaps you're right. I'll rephrase:

    Only once since 1776, has there been a decade in which four of the years were prime numbers. Can you find it?
