Veterans Day is a legal holiday which means all state, county and municipal offices, including banks and your local post office are closed for the day. Most retailers are open. Both the Holyoke and the Eastfield Malls are open for their normal business hours.
According to the holiday schedule on the United States Postal Service website, there will be no mail delivery and all USPS branches will be closed on Veterans Day. If you need to mail a package, take care of that on Monday or wait until November 12 when the post office opens again.
