No, 4000 will not be a leap year according to the current Gregorian calendar rules. These rules state that a year is a leap year if it is divisible by 4, except for years that are divisible by 100, unless they are also divisible by 400. However, the year 4000 breaks this pattern by introducing an exception to ensure the calendar remains aligned with the Earth's revolutions around the Sun. Thus, under these refined rules, 4000 is treated as a typical non-leap year.
