A new day to fall between Saturday and Sunday. Extending the week to 8 days a week.

The day would be used to take part in all those things that you really don't have time for at the weekend. Every slobbish, bad for you, hedonistic thing that you wish you could do but because the weekend is so short you don't have time to recuperate.

Sunday is now just like any other day. We need another day in the weekend to make up for it. Bring on Sinday!

What are you doing this Sinday? Fancy going on an all day bender?

Am not getting out of bed today, I can do the chores on Sunday. Today is Sinday!
