The months calculation returns the number of complete months between two dates. So, 20th Feb to 19th Apr would be 1 month, but to 20th Apr would be 2 months.
You can use: new Period(date1, date2, PeriodType.yearMonthDay()) to get the whole period in days, months and years, or try this method to get closer to your needs: Period.fieldDifference(date1, date2) If you only care about dates (and not times) try using LocalDate rather than DateTime.
