In addition to April Fools' Day, Monday will be Opening Day in Major League Baseball. OK, technically, the 2013 Championship Season starts tonight when the Texas Rangers welcome the Houston Astros to the American League, but most major league teams are scheduled to start play on Monday, April 1... weather permitting.

If you can't ditch work and head out to the ballpark today, do not despair. Some of the Usual Suspects tout Monday as National Fun at Work Day (one goes so far as to proclaim it International Fun at Work Day).

Of course, we're a little skeptical when 'fun' and 'work' are used in the same sentence -- and having too much fun at work may well be hazardous to your long- and short-term employment prospects. The Blog of Days can not be responsible for the consequences of your celebrating Fun at Work Day.

Steve Jobs, Steve Wozniak, and Ronald Wayne founded Apple on April 1, 1976, and that was certainly no joke.

And there is an odd coincidence of Air Force anniversaries on April 1:

• The British Royal Air Force was founded on April 1, 1918;
• The Royal Canadian Air Force was founded on April 1, 1924; and
• President Dwight David Eisenhower signed legislation authorizing the foundation of the United States Air Force Academy on April 1, 1954.
