Presidents' Day for the year 2004 is celebrated/ observed on Monday, February 16th.
President's Day, also known as Washington's Birthday, is on the third Monday of February each year and is a federal holiday in the United States. The day not only honors George Washington (born February 22), the first President of the United States, and Abraham Lincoln (born February 12) whose birthdays are both in February, but honors all the presidents who have served in the United States.
Uniform Monday Holiday Act
On June 28, 1968 the United States Congress passed the Uniform Monday Holiday Act  changing many federal holidays to move over to Monday from other days of the week. Originally Washington’s Birthday was celebrated on February 22nd each year but was permanently moved in 1968 with the signing of the new Act. So the new date of President’s Day will fall between February 15 and the 21st each year and never on his (Washington’s) actual birthday of February 22nd.
