Is there mail today 9 11

You're referring to September 11th, a significant date in American history.

On September 11, 2001, a series of coordinated terrorist attacks were carried out in the United States, resulting in the loss of thousands of lives. The attacks involved four commercial airplanes being hijacked by terrorists, with two planes crashing into the Twin Towers of the World Trade Center in New York City, one plane crashing into the Pentagon in Arlington, Virginia, and one plane crashing into a field in Shanksville, Pennsylvania.

In the aftermath of the attacks, the United States Postal Service (USPS) suspended mail delivery for several days, from September 12 to September 15, 2001, as a mark of respect and to allow for the recovery efforts.

However, since then, mail delivery has resumed on September 11th, and it is considered a regular business day. The USPS operates on a regular schedule, including mail delivery, on September 11th.

It's worth noting that while mail delivery continues, many government offices, schools, and businesses may observe a moment of silence or hold special ceremonies to commemorate the anniversary of the 9/11 attacks.
