In the United States National Day of Reason is celebrated on May 04, 2017. The day is a celebration for humanists, atheists, and other secularists and freethinkers, taking place the first Thursday in May of every year. It coinces with National Day of Prayer, which is a legal holiday in the United States. The day aims to celebrate reason "and to raise public awareness about the persistent threat to religious liberty posed by government intrusion into the private sphere of worship." Also, the days' purpose is to build a non-religious community in the United States. A positive, useful, constitutional alternative to the National Day of Prayer is tried to be given by the National Day of Reason.
