Why are the calendars years 2095 2101 and 2107 all identical to 2089 - calendars do not repeat after eighteen years?

The pattern usually changes when counting from one century to another since most years that are evenly divisible by 100 are regular years. Regarding years that are multiples of 100, only every fourth one is a leap year (e.g. 1600, 2000, 2400, etc.). In your example, each six-year period between years included five regular years and one leap year. For each regular year you advance one weekday, and for each leap year you advance two weekdays, then you check to see if the total is a multiple of 7 and if it's the same type of year you started from (leap or regular).
