Did Supernatural on the CW change nights? It used to come on Thurs at 9.?

Like practically every other scripted show on TV, it ran out of scripts due to the strike and went on hiatus. The strike has only been over for a month, but it generally takes 6-8 weeks or more to write, cast, film and air an episode. They are working on filming the new scripts that have just been written, but the new episodes won't be ready to air until April.
