A national holiday but not a public holiday. Why on that day? There is a reason. During the communist times all cities were decorated with red and white flags for the celebration of 1st May. But there is a very important holiday on 3rd May which was not accepted by the communists and for many years it was banned. That was why all the flags for 1st May celebrations had to be taken down by 3rd May. Leaving a flag up that day could bring serious trouble. This holiday has been recently re-instated and was declared official in February 2004 by the Polish Sejm. It awakens patriotism for their country in the soul of the Polish people and there are many concerts and shows on that day in Poland.
