Why are election years even numbered?

Election years are typically even-numbered to create a consistent schedule for federal and state elections, including the U.S. presidential elections, which are held every four years on the first Tuesday after the first Monday in November. This timing helps avoid conflicts with other significant events, such as holidays, and aligns with the agricultural calendar, allowing rural voters to participate more easily. Additionally, having even-numbered years promotes synchronization among various election cycles, making it simpler for voters and officials to manage the electoral process.
