    There's nothing wrong. It's returning the days field, not the equivalent of the entire period in days. Try `p.getYears()`, and you'll get `1` – ernest_k Oct 11 '18 at 11:38
  • please suggest how to find days between two dates using LocalDate? – SUVAM ROY Oct 11 '18 at 11:40

    `ChronoUnit.DAYS.between(start, end)` (returns 365 in your case). – Ole V.V. Oct 11 '18 at 11:40

The result period contains 1 year, 0 month and 0 day. You just print the number of days, i.e. 0.

  • If I don't know in what difference user will input the dates then how to find the days? e.g start:2018-10-15 end:2018-10-25...the code worked fine but not for the above case..what to do then? – SUVAM ROY Oct 11 '18 at 11:48

0 is the difference between days. If you print p.getYears() You will see 1.

As already mentioned by soon , Period lists 1 year in your case (P1Y), here you are trying to convert 1 year in number of days since the number of days is 0 it lists 0. How to calculate the number of days in a period?

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy", Locale.ENGLISH);
Date firstDate = sdf.parse("06/30/2017");
Date secondDate = sdf.parse("06/30/2018");

long diffInMillies = Math.abs(secondDate.getTime() - firstDate.getTime());
long diff = TimeUnit.DAYS.convert(diffInMillies, TimeUnit.MILLISECONDS);

System.out.println(diff);
