Father's Day is a day set apart in many countries for honoring fathers. In the US, UK, and Canada, it is observed on the third Sunday in June. The idea for a father's day originated when Sonora Louise Smart Dodd of Spokane, Washington, heard a sermon on Mother's Day in 1909 and was inspired to create a date to honor fathers like her own, a Civil War veteran. Through her efforts, the first Father's Day was celebrated in Spokane in 1910. When was the holiday made official in the US?
