“Occurred” is the correct spelling. “Occured” is a common misspelling because the final “r” must be doubled.
You’re writing an email, school paper, or social media post when you type a sentence like:
“The accident ___ yesterday.”

People search for “occurred or occured” because they want to know:
- which spelling is correct
