Many know Memorial Day as the unofficial start of summer, but what is it, really?
Although Veteran's Day was established to honor all veterans, Memorial Day is about honoring military service members who died in the line of duty.
Here's a quick history lesson:
After the Civil War, America lost so many soldiers that the country had to establish national cemeteries.
In the 1860s, people began showing up at those cemeteries in spring to freshen up flowers at the graves and pray.
In May 1868, a national day of remembrance was established — then called Decoration Day.
That led to the national establishment of Memorial Day in 1971.
Lately, though, the day seems to be more about barbecues and paid time off than remembering fallen military members.
So if you want to keep the true meaning of the day in mind, it's best to avoid saying, "Happy Memorial Day."
