Easter falls on a spring Sunday that varies from year to year. Easter is a Christian holiday celebrating the resurrection of Jesus Christ. For Christians, Easter is a day of religious services and the gathering of family. Many Americans follow old traditions of coloring hard-boiled eggs and giving children baskets of candy.
Earth Day is observed on April 22. First celebrated in 1970 in the United States, it inspired national legislation such as the Clean Air and Clean Water Acts. Earth Day is designed to promote ecology, encourage respect for life on earth, and highlight concern over pollution of the soil, air, and water.
National Arbor Day was proclaimed as the last Friday in April by President Richard Nixon in 1970. A number of state Arbor Days are observed at other times to coincide with the best tree planting weather, from January and February in the south to May in the far north. The observance began in 1872, when Nebraska settlers and homesteaders were urged to plant trees on the largely treeless plains.
