The 1990 calendar is the same as the calendar for 1934, 1945, 1951, 1962, 1973, 1979, 2001, 2007, 2018, 2029, 2035, 2046: every date falls on the same day of the week, so a calendar from one of those years can be used for 1990.
Between 1930 and 2050: 1934, 1945, 1951, 1962, 1973, 1979, 2001, 2007, 2018, 2029, 2035, 2046. They start on the same day of the week and are also common (non-leap) years.
