"Today is Friday."
Here is something for you etymologists out there: In Korean, the word for weekend is 주말, pronounced jumal. Its not a stretch to count friday, cuma, and obviously saturday, cumatesI, as the weekend. Add to that how some people consider Sunday the first day of the week!
In search of similarities between Korean and Turkish (because of the whole altaic language family debate) this is one of the few words similarities i've noticed so far.
