Contacts is changing birthdays by one day
When I enter a new contact with their birthday, it automatically changes it by one day (moving forward) and then it shows in my calendar as two separate days. Even when I try and change the birthday it still changes it. This is extremely annoying and would be great if the glitch could be fixed. All my devices are affected, it doesn't matter if I do it on my iPad, iPhone or MacBook... same result.
iPhone 7, iOS 12
