Is today Christmas Week?
Yes, Christmas is in three days sweetheart.
No, it's Halloween.
Just a few days until christmas...
Yes and Merry Christmas
Why, yes it is.
Last I checked it is. Actually, Christmas is in 3-ish days
A day cannot be a week, because a week is 7 days. But if you meant, "Is today part of Christmas week?", then yes, it is.
