Polls open at different times depending on your state and locality. Since you’re asking about “tomorrow,” the exact opening time varies by where you vote. Here’s how to get a precise answer quickly:

• Check your state or local election office website: look for Election Day hours or polling place hours.
• If you know your county or city, you can search for “polling place hours [your state] [your county/city]” or use your state’s voter portal.
• Other reliable sources that typically publish statewide opening times include major news outlets’ election sections and Ballotpedia’s State Poll Opening and Closing Times page.

What to do right now:

• Tell me your state (and, if possible, your city or county), and I’ll provide the exact opening and closing times for tomorrow and note any lines-in-progress rules (e.g., if you’re in line at closing time you can still vote).
