Initial unemployment claims for September 1

Last time, I said:

If, and that's a big if, there are any shenanigans going on regarding these announcements, the number for the week ending August 25th might be revised higher to, say, 377,000 or so, and the advance number for the week ending September 1st might come in at about 375,000, and people can put headlines pointing out how the unemployment situation is getting better.

The report is now out. It says, and, I kid you not:

In the week ending September 1, the advance figure for seasonally adjusted initial claims was 365,000, a decrease of 12,000 from the previous week's revised figure of 377,000.

So, the figure for the week ending August 25th was revised up by 3,000 from 374,000 to 377,000, as I thought it would.

I am not sure how the figure for week ending September 1 went all the way down to 365,000.

I am assuming there is a Labor Day related anomaly here. The decrease in unrevised, unadjusted initial claims was just 4,280.
