Forefather's Day is commemorated as a national holiday in Plymouth, Massachusetts, on the 22nd of December. According to the Georgian calendar, Forefather's Day was erroneously constituted on the 22nd of December in place of 21st December, 1620.
The history of Forefather's Day dates back to the year 1620 with the land of Pilgrims on the Mayflower and formed the second colony in North America. Though different sources assert Forefather's Day to be a regional holiday in New England, it was once used to be celebrated in New Jersey.
The actual celebration of Forefather's Day was observed when the Pilgrims set their first foot on land on the 22nd of December in the year 1621. To escape the religious persecution, they had sailed from Plymouth, England on September 16.
Although the Plymouth Rock is the traditional place of landing of the Pilgrims in New England, it is also an important symbol in the history of the United States. The land of Pilgrims on the Plymouth Rock was then an inaccessible Wampanoag village of Patuxet, but was considered as the beginning of formation of the United States of America 155 years later.
Forefather's Day was first celebrated in the year 1769 by the Old Colony Club of Plymouth remembering the great sacrifices of the Pilgrims and Wampanoag Native Americans. But since this celebration was only 15 years after the introduction of New Style Calendar, there was confusion among the Club members about how many days to be added to the original date of landing of the Pilgrims on December 11.
All the dates before the year 1700 were improbable to have 10 days added to the New Style Calendar, and all dates after the year 1700 have to be added 11 days to it. For some reason a mistake was made, and the Old Colony Club members however celebrate Forefather's Day on the 22nd of December.
The Old Colony Club of Plymouth, a group of people who were interested in the history of Plymouth; formed The Pilgrim Society, which holds a meeting annually on the 21st of December. They celebrated this day by wearing top hats led by a drummer marching down the main street of Plymouth by serving a traditional dinner of succotash, stew, corn, turnips, and beans.
