I would like to propose a new sales holiday.
I propose "Blue Thursday." It would fall on the day _after_ Christmas, each year.
Why blue? Because that's how you feel each year the day after Christmas, when it hits you just how much you've spent--and overspent, how many days you're going to have to work to pay for it all, and the interest on credit cards that will accrue--before you pay it all off (whatever happened to "Christmas _savings_ accounts"?). _Et al._
Since this sales holiday will always fall on the day after Christmas, it will become easy to remember. The day of the week will change each year, however. I've checked the calendar, and next year it will be "Blue Saturday". You won't need to circle the date on your calendar--being the day after Christmas, you'll automatically know the day of the week every year!
Whaddya think? Will people go for it? Personally, I predict that it will be a big hit, once people get used to it.
Remember: you heard it on MobileRead first.
