Will the calendar ever line up correctly, or will we continue to have these time issues with fractions of days?

Its a great theory and explanation that why a leap year exists, except that people from different culture and part of the globe wont align or agree to this. This would shake and shame people who has half knowledge and blindly believes time based astrology. May be one side of the argument will be more precise an other sides will be less.

With the seasons lasting longer or sometimes being shorter, will the calendar ever have to be altered to fit these changes?
