Ok, I understand in some ways why they combined them all into one… but not completely. Here is what many of the sites say (this is from britannica.com):
In 1968 Congress passed the Uniform Monday Holiday Bill, which moved a number of federal holidays to Mondays. The change was designed to schedule certain holidays so that workers had a number of long weekends throughout the year, but it has been opposed by those who believe that those holidays should be celebrated on the dates they actually commemorate. During debate on the bill, it was proposed that Washington’s Birthday be renamed Presidents’ Day to honour the birthdays of both Washington (February 22) and Lincoln (February 12); although Lincoln’s birthday was celebrated in many states, it was never an official federal holiday. Following much discussion, Congress rejected the name change. After the bill went into effect in 1971, however, Presidents’ Day became the commonly accepted name, due in part to retailers’ use of that name to promote sales and the holiday’s proximity to Lincoln’s birthday. Presidents’ Day is usually marked by public ceremonies in Washington, D.C., and throughout the country.
Guess I can’t complain too loudly… as I like my 3-day weekends. Then again, it’s a 4-day weekend here… the boys have Tuesday off for Teacher Work Day. I wonder how the kids learn with so many days off… it’s crazy.
