On November 27th, North Americans will celebrate Thanksgiving, an annual holiday during which families and friends get together for a scrumptious feast and reflect on all the things they are grateful for. The ancient tradition dates all the way back to 1621, when the pilgrims celebrated their first harvest with a feast that lasted for three days. While most people are aware of that, very few know that the holiday was once celebrated several times a year or that Thanksgiving as we know it today, is possible thanks to 19th century writer, Sarah Josefa Hale.
