We celebrate by having pie. A family tradition. One of my husband’s favourite day of the year. 3rd month, 14th day. My husband is a wizard at math. He is a computer programmer and deals with numbers all day. He always makes fun by comparing birthdates and ages with number configurations.
Today, out of the blue, at 3;14 pm, he calls down the stairs from his office, “Happy Pi day”. Lol!! Never a dull day!
