JK Rowling's Mother's Day tweet made everyone in the US panic
Mother's Day: a time for giving your lovely Mum a great big hug or remembering just how much they supported and cared for you.
The day is special on both sides of the Atlantic. However, it comes with a warning: British people celebrate Mother's Day on a different day to people in the United States.
This proved a real problem when Harry Potter author JK Rowling tweeted this lovely tribute to her mother Anne, only for her fans in the US to freak out with worry that they might have forgotten this all-important date.
