How often does July 7th fall on a Saturday?

Answer 1

It happens every 5th, 6th or 11th year and works out as 4 times in every 28 years, though not a 7 year intervals. If you look at the list of when it happened from the start of the 20th century to 2014, you will see a pattern of year gaps of 11, 6, 5, 6. Then the pattern repeats, as follows: 1906, 1917, 1923, 1928, 1934, 1945, 1951, 1956, 1962, 1973, 1979, 1984, 1990, 2001, 2007 and 2012. Continuing the pattern, there is a 6 year gap, so the next time will be in 2018.
