Allowing for Religious Holidays

This school year our school district not only gave the students Yom Kippur (as is usual) but also Rosh Hashanah off. Isn't it possible then to recognize one day each year for each of the major religions represented in the district? As it is our district gives two weeks for Christmas/New Year's and also Good Friday. Isn't this the Nation that boasts religious freedom? We can teach our children the meaning of religious tolerance by allowing other faiths the same "air time", so to speak. It's not at all difficult to accommodate if only we try.
