The 2011 calendar is the same as the calendar for 1955, 1966, 1977, 1983, 1994, 2005, 2022, 2033, 2039, 2050, 2061, 2067: every date falls on the same day of the week, so a calendar from one of those years can be used for 2011.
Between 1951 and 2071: 1955, 1966, 1977, 1983, 1994, 2005, 2022, 2033, 2039, 2050, 2061, 2067. They start on the same day of the week and are also common (non-leap) years.
