US Expats: passport expiring in March 2021

As the title says, my passport will expire in March next year.

I am planning to go to the US in November/December (COVID notwithstanding). I am a resident where I currently live (EU). I’d like to think I wouldn’t have any trouble traveling and then renewing my passport when I return to EU in December.

What are your experiences with this? I’ve also heard that I shouldn’t travel if my passport expires in the next 6 months... meaning I should renew it ASAP and hope it’s done before November?

Thanks!
