Short answer: You’re likely voting tomorrow because many elections are scheduled for a Tuesday in early November, with Election Day falling on the Tuesday after the first Monday in November. The exact reasons and races depend on your location, but common factors include scheduled local, state, and sometimes national contests, plus early voting options in many areas. Details and context

• Election timing: In the United States, Election Day is traditionally the Tuesday after the first Monday in November. This places general election days on dates like November 4–8, depending on the year, with variants for state and local elections [web results indicate this general pattern and the rationale behind Tuesday choice].
• What’s on the ballot: Localities often hold elections on these days for offices such as mayors, city council, school boards, and state legislative seats, as well as referendums or ballot measures. The exact offices and measures vary by city, county, and state.
• How to verify for your location: Check your local or state elections office website or trusted voter information sources for:
  • Your polling place and polling hours
  • Early voting periods and locations
  • The specific ballot items and candidates in your precinct
  • Any required identification or registration status
• Common sources of confusion: Some jurisdictions schedule off-year or special elections on different days, and ballot items can differ dramatically from one locality to another. If a nationwide or national race isn’t on your ballot, that’s typical for many local election cycles.
