It's the way you worded it. You should probably make a time chart instead.
Feb. 8 - something a.m. to 8 p.m.
and so on. Avoid the word "Closed" because that's all they're reading.
Will be closing EACH night between Feb 8 - 13th at 8:00 pm.
I read it the other way too.
What!!! Closing time! But I don't understand????
Because that is what it says, closed from 8pm no the 8th through sometime on the 13th.
