In case you didn't know, let me be the first to wish you a happy National Egg McMuffin Day.

And to celebrate, McDonald's is giving away free McMuffins all morning long at participating locations.

To score the free breakfast sandwich, you will first need to download the McDonald's mobile app to access the in-store offer.

Then, head over to a McDonald's today (3/2) between 6:00 am and 10:30 am to scoop up your free McMuffin.

By the way, the Egg McMuffin made its debut in 1971 and "changed the breakfast game forever." One of the unique qualities of the sandwich is that it's made with a freshly cracked egg, not an egg patty with various fillers.

Happy dining.
