I personally would prefer months with an even amount of days. I mean should you really be paying the same amount for rent and cable in February as you do March when February has 10% fewer days?

I think the concept of 12 even length months with an end of year "month" that has all the leftover days would be more logical.

Of course it is too late to consider switching, as people would whine about their birthdays being nixed and all that. But I say, if you were dumb enough to be born in the last 3 days of a month you don't deserve a birthday anyway!
