The 1977 calendar is the same as the calendar for 1921, 1927, 1938, 1949, 1955, 1966, 1983, 1994, 2005, 2011, 2022, 2033: every date falls on the same day of the week, so a calendar from one of those years can be used for 1977.
Between 1917 and 2037: 1921, 1927, 1938, 1949, 1955, 1966, 1983, 1994, 2005, 2011, 2022, 2033. They start on the same day of the week and are also common (non-leap) years.
