Difference in days between two dates in Java?

Question

I need to find the number of days between two dates: one is from a report and one is the current date. My snippet:

  int age=calculateDiffer         


        

Answer 1

It depends on what you define as the difference. To compare two dates at midnight you can do.

long day1 = ...; // in milliseconds.
long day2 = ...; // in milliseconds.
long days = (day2 - day1) / 86400000;
