Well, I don't actually know the specific 'the day everything went wrong story'. But generally, it could be about a day when a person woke up late, missed the bus, then got to work or school and found out they had forgotten an important assignment. Maybe they spilled coffee on their clothes during lunch and later got into an argument with a friend. It's all about a series of misfortunes that happened in one day.
One possible element could be bad weather. If it's pouring rain and you don't have an umbrella, that can start a series of problems. Another could be miscommunication. For example, getting the wrong time for an appointment. Also, technical problems like a phone dying when you need it most.
It could be a series of unfortunate events like missing an important appointment, having a fight with a loved one, and losing something valuable all in one day.
