McDonald’s is days away from officially launching the return of a seasonal favorite: the Shamrock Shake. The celebratory St. Patrick’s Day drink will arrive on Feb. 10, just over a month before the holiday arrives.

McDonald's announced when the Shamrock Shake will return. Here's what to know including what it tastes like, ingredients and how many calories it has.

McDonald's popular Shamrock Shake typically comes back well ahead of spring, and this year is no exception. Some of the Chicago-based fast food giant's locations have already begun offering the sweet concoction. You just might be able to get your hands on one early -- if your local McDonald's has rolled it out.
