Otherwise you will be forced to use the one you had for Christmas from Aunt Vicky, showing Yorkshire's picturesque country lanes or mischievous puppies in a variety of baskets.
Why do we have calendars? We have calendars because New Year falls on a different day every year, Easter has a mind of its own and we all need something to send as presents to people we don't know very well.

So January was dedicated to Homer and October to Shakespeare. To make up the numbers Comte added an extra day at the end of the year, which would not have a day of the week assigned to it. …
