No Mail Delivery in Chicago on February 21, 2011: Federal Holiday Observance

There was no mail delivery in Chicago—or anywhere in the United States—on February 21, 2011. The date fell on a Monday, which was the observed federal holiday for Washington's Birthday (commonly known as Presidents' Day).

Under federal law, Washington's Birthday is celebrated on the third Monday of February. The United States Postal Service (USPS) suspends regular mail delivery and retail services on all federal holidays, resuming normal operations the following business day.
