The day of the week of any date is different each year. It usually advances by one weekday from one year to the next, but it advances an extra weekday when there is a February 29 during the intervening year. For example, since New Year's Day of 2015 is a Thursday, New Year's Day of 2016 is a Friday, and, since 2016 is a leap year, New Year's Day of 2017 is a Sunday.
