Lots of people call today Blue Monday because it's apparently the day when many people feel a bit fed up.

Scientists worked it using a mathematical formula that takes into account the weather, the length of time since Christmas and even levels of motivation.

But at Newsround they're forgetting Blue Monday and asking; what are you feeling happy about today instead?

here are the comments they received
