What would you call the eighth day of the week?

The 7 day week was introduced to the west by Rome in AD 321, but before that they had 8 days.
The Burmese week is composed by eight days.
The welsh word for week, wythnos means 8 nights (wyth 8 nos night)

I think it makes more sense to have an 8 day week because it's easier to divide up. Half a week 4 days not 3.5 days. Besides you all complain there's never enough days in the week.

Therefore from next week I declare there will be 8 days in a week and just to be nice I'm letting you name the eighth day, so what's it going to be?
