Thanksgiving day is celebrated at the fourth Thursday of every November. But this was always not so. President Abraham Lincon has designated the last Thursday of every November to be thanksgiving day. But sometimes, the last Saturday used to be the fifth Saturday, which would be too close to Christmas. Hence, President Franklin D. Roosevelt designated the fourth Thursday of November to be Thanksgiving day in 1939, which was approved by Congress in 1941. Below we are giving the dates of Thanksgiving day from 2008 to 2014. Check them out and plan out your grand celebration! We are also giving some past thanksgiving dates for your records.
