Labor Day- that is the first Monday in September.
Labor Day used to signify that school was about to start- tomorrow! But, that calendar is no longer in vogue. Some schools started last week and some even began two weeks ago. Others won’t start for yet a few more days. But, it still is the harbinger of summer’s end for most of us. (Yes, I know that Autumn begins on 23 September [it used to be on 21 September], but the pools close today…)
