Local holidays.

CaptAmehrican thought this was worth mentioning said

Does your location celebrate a holiday the rest of the nation/world doesn’t? What is it? How do you celebrate?

Fyi today is Defenders Day the annual celebration of Maryland winning the war of 1812 due to the battles in Baltimore sending the British packing and they sued for peace afterwards (not the star spangled banner is about these battles) (also note battle of new Orleans the USA won but occurred after peace had been declared)
