McDonald’s (MCD) has declared that Monday is National Egg McMuffin Day, nearly fifty years after first introducing the breakfast sandwich. To celebrate, the fast-food chain is offering free Egg McMuffins.

To get a free Egg McMuffin from McDonald’s, customers need to download the restaurant’s mobile app and redeem the offer between 6 a.m. to 10:30 a.m. local time on Monday. The offer is available nationwide at participating McDonald’s locations.

“While we’re giving the Egg McMuffin its moment, we’re really honoring our breakfast fans who have woken up with McDonald’s breakfast for nearly 50 years. And we just thought, ‘Hey, why not declare March 2 as National Egg McMuffin Day?’,” David Tovar, vice president of U.S. communications at McDonald’s, said in a statement.

“We’re always looking for new ways to show our fans love and remind them, no matter where they might be, a great tasting and convenient breakfast is just around the corner for them at McDonald’s,” he added.

The Egg McMuffin was introduced in 1971 by Santa Barbara, California, owner and operator Herb Peterson as an attempt to create Eggs Benedict. Peterson also created the Teflon rings that give McDonald’s eggs their perfectly round shape.

Shares of McDonald's stock were down 4.59% as of 12:32 p.m. EST on Friday.
