On January 21, 2019, Americans all over will most likely have the day off. On this day we honor the work of famous civil rights activist Martin Luther King Jr. whose birthday was on January 15, 1929 and would’ve turned 90 this year. Ever since 1983 when President Ronald Reagan made it official we get this day off as Americans. So this Monday, whether you have the day off or not, it might be hard to know what will or won’t be open.
