Last weekend (Novemebr 4th-6th), both WLYT-102.9 and WKQC-104.7 went all-Christmas for the weekend, but went back to their regular Adult Contempoary formats with the start of the new week.
According to the playlists on Yes.com, WLYT-102.9 has apparently gone all-Christmas.
At 2:49 P.M. EST today (November 11th), the station played Garth Brooks' version of "White Christmas", and at this writing (3 P.M. EST), the Yes.com playlist for WLYT shows that the station has been all-Christmas ever since.
By contrast, WKQC-104.7 is still (as of just before 3 P.M. EST) programming their regular AC format, but their website has an all-Christmas look
. But I'd suspect WKQC will quickly follow suit. They did last week for a "preview" weekend.
Given the calendar, I suspect WLYT is all-Christmas for the duration. And WKQC probably follow suit soon.
