does mail run on christmas eve

Yes, mail delivery typically continues on Christmas Eve, although it may be delayed or have reduced hours. The U.S. Postal Service (USPS), for example, delivers mail on Christmas Eve as long as it is not a federal holiday in your area. The USPS may adjust its delivery schedule to accommodate the high volume of packages during the holiday season, so it's recommended to check with your local post office or visit USPS.com to confirm their operating hours on Christmas Eve.
