Yes, you heard right. National Waffle Day is a holiday that originated in Sweden. It is called "Våffeldagen" in Swedish. The holiday coincides with the Feast of the Annunciation, a religious event. In addition, "Waffle Day" on March 25 has always been considered the start of spring - especially in Sweden. It became a custom for Swedish families to celebrate the two events by making waffles on this day.
Today, many Swedes forego the religious part of the celebration but most still have waffles for dessert, topped with jam or whipped cream. So if you're traveling through Sweden on March 25, make sure to leave room for dessert! Also see:
