BTW, we already have two added months that throw off the original 10 month calendar and the meaning of the names of some months. Julius and Augustine if I remember correctly. Sept = 7 and Oct = 8. So, why not just take away days we don't like. We could just add them into the end of the year as party days like some cultures do. In a similar vein I've been in a lot of buildings that skip the 13th floor.
