Calendar maker

This won't happen for another 850 or so years.

I wonder what wars will be happening then, or what new inventions will enable us to move about the earth and sky.

But having a month with 5 Fridays, 5 Saturdays and 5 Sundays is that rare...assuming this is the calendar we use that far in the future.

And will there still be people around with days having names that refer to ancient pagan gods?

Ah, Woden-day, Thors-day, Freyas-day, and Saturn-day...I think you will have been surpassed by other names by then.  Moon and Sun should still be around.  Don't remember who Tuesday was named after.

Enjoy it, when it happens.  We only really have one day, today.
