Okay - but this is going to be a weird calendar, if it doesn't handle
months.  (Or minutes, which have a similar -- although less frequent
-- problem with seconds)

(Which is one reason I argue that calendar units should be an algebraic
data type, and not a record.)

If I haven't seen further, it is by standing in the footprints of giants
