Yes, it ends at 0:00 on the 14th, which means it ends at 12:00 on the night of the 13th.

Have you ever played a challenge match? I have a question to ask you. As of 14.8, do asp, ta, and zrc not need to be brushed today? I just reached the minimum amount for the first time, but I don't know if I still need to brush them today?
