Is there mail on september 11 2023

A clever question!

As of my knowledge cutoff in 2023, the United States Postal Service (USPS) operates on a regular schedule, including on September 11, 2023.

However, it's possible that some post offices or mail processing facilities might have special hours or closures on September 11, 2023, due to the anniversary of the 9/11 attacks. This would depend on the specific location and any local or national events that might be planned.

To confirm, I recommend checking with your local post office or the USPS website for any potential changes to their operating hours or services on September 11, 2023.
