For Veterans Day, restaurants and businesses across the U.S. are recognizing the sacrifice of veterans and active-duty military personnel with free meals, deals and discounts.

The federal holiday, which is Saturday, is held on Nov. 11 to mark the end of World War I when the Allies and Germany signed an armistice agreement on Nov. 11, 1918 – fighting ended on the 11th hour of the 11th day of the 11th month, according to the Department of Veterans Affairs.

But the date itself is meant to honor all those who served in the military, those who are living and those who have died.

Many of these deals are for Saturday, but some are good on Friday, and others over the weekend. Most discounts require proof of service, such as a form of veteran, military or military-dependent identification. Many offers are limited to dine-in guests as well. Always check with your closest location to confirm participation.
