It's a day earlier than normal, but Happy Doctor's Day. The "holiday" is normally celebrated on March 30 but since that is on a Saturday this year, it was moved up to today. Obviously we can't move it to next Monday, which would make it April 1, or April Fool's Day though some people might think that is more appropriate. Of course some wag in our office said every day at the hospital is doctor's day.
Here is a brief history of National Doctor's Day.
