Take it in the Ear Day
Take it in the Ear Day is referenced by various holiday webpages, but no one seems to know why it was created, or who created it. Maybe it's a day for people to intently listen to others, or to let someone yell at you without responding. Maybe it's a day to get your ears cleaned out at a doctor's office, or to get your ears pierced. Still, maybe the name of the day is a euphemism for something else, or a slang way of telling someone to "stick it". If the creator of the day would have made sure someone else took the reasoning behind the holiday in their ear, we would all know what the day was about.
How to Observe
Most likely you should be taking something in your ear figuratively today. Listen to some music or a podcast, or have a conversation with someone. But, since there is no consensus on how to celebrate, how you do so is open to interpretation.
