How we source and verify voting deadlines

Last updated October 5, 2026

Every deadline on Vote Clock is sourced only from official government election offices, shown with a link to that office and the day we last checked it. This page is the whole method, so a voter, a teacher or a newsroom can check our work.

Who is behind Vote Clock

Vote Clock is operated by Election Media LLC, an Illinois company, and is funded by its founder. It takes no money from candidates, campaigns, political parties or political action committees, and it shows no ads. It is a free voter deadline tool with no sign-up and no personal data collected, and it doesn't sell or share your information. Privacy policy.

Where a date comes from

• Government sources only. A state or local election office, an official election calendar, or state law. Never a news report and never another voter website.
• Read from the office's own page. A date that appears on three other sites is still one unchecked date. We read it on the government page itself.
• Every source link goes to a government page. Each deadline names its source and links to it.

What we show, and what we won't

• The hour, only when it is official. Where a state sets a clock time, such as 4 p.m. or 9 p.m., we show it and count down to it in that state's time zone. Where there is no statewide hour, we say "by your local election office's close of business" and never count down to a midnight the state didn't set.
• Each way to register has its own date. Online, in person and by mail can close at different times, so each is listed separately.
• No guessing. If we can't confirm a date on a government page, we don't show it. We say we're still verifying and send you to that state's election office.
• No polls and no predictions. Vote Clock helps you vote. It doesn't forecast who wins.

How we keep dates right

• "Checked" dates. Each deadline shows the day we last confirmed it against its source. The countdown you can embed shows it too.
• A watch on the data. An automatic check runs every five minutes and alerts us if a page, the countdown's data or any published deadline changes or stops answering.
• AI checks, a person decides. AI helps us compare dates with official pages and watch for rule changes. It never changes a deadline. A person makes every change.

Corrections

Use "Report an error" under any state's dates, or email [email protected]. A report never changes a date by itself: AI compares the date with the official page and recommends, and a person decides. If we were wrong, we fix it promptly and update the "Checked" date. If we can't confirm a date quickly, we hide it and point voters to the official election office until we can.

Vote Clock is not a government website. Your state or local election office always has the final word. More about Vote Clock.
