Election Day refers to the day when citizens go to their polling places and cast their votes in a public election. It is usually held on a Tuesday, which has become known as "Election Day" because it was considered an optimal time for voting by the general population since many people would not have to take time off from work or school to vote. The term can also refer to the day when elections are held in different countries and jurisdictions at various times throughout the year, depending on local laws and customs.
