Earth Day is honoured around the world on April 22, although larger events such as festivals and rallies are often organized for the weekends before or after April 22. Many communities also observe Earth Week or Earth Month, organizing a series of environmental activities throughout the month of April. Nearly thirty students of the Faculty of Natural Sciences, Constantine the Philosopher University in Nitra (UKF) and members of the organization Raptor Protection of Slovakia (RPS)will donate 5 days to celebrate Earth Day with several activities, e.g. monitoring of electric power lines.
