What about teacher appreciation day?

How can tell me something about teacher appreciation day?

In the United States, Teachers' Day is a non-official holiday on the Tuesday of the first full week of May.

The National Education Association (NEA) describes National Teacher Day as 'a day for honoring teachers and recognizing the lasting contributions they make to our lives' [3]

The NEA gives a history of National Teacher Day:

The origins of Teacher Day are murky. Around 1944 Arkansas teacher Mattye Whyte Woodridge began corresponding with political and education leaders about the need for a national day to honor teachers. Woodbridge wrote to Eleanor Roosevelt who in 1953 persuaded the 81st Congress to proclaim a National Teacher Day.
NEA along with its Kansas and Indiana state affiliates and the Dodge City (Kan. ) local lobbied Congress to create a national day celebrating teachers. Congress declared March 7, 1980, as National Teacher Day for that year only.
NEA and its affiliates continued to observe Teacher Day on the first Tuesday in March until 1985, when the National PTA established Teacher Appreciation Week as the first full week of May. The NEA Representative Assembly then voted to make the Tuesday of that week National Teacher Day. [4]
As of September 7, 1976, September 11 was also adopted as Teachers' Day in the U.S. state of Massachusetts
