Number of days between two dates in Joda-Time

How do I find the difference in Days between two Joda-Time DateTime instances? With ‘difference in days’ I mean if start is on Monday and end is on Tuesday I expect a return value of 1 regardless of the hour/minute/seconds of the start and end dates.

Days.daysBetween(start, end).getDays() gives me 0 if start is in the evening and end in the morning.

I'm also having the same issue with other date fields so I was hoping there would be a generic way to 'ignore' the fields of lesser significance.

In other words, the months between Feb and 4 March would also be 1, as would the hours between 14:45 and 15:12 be. However the hour difference between 14:01 and 14:55 would be 0.

java.time.Period

Use the java.time.Period class to count days.

Since Java 8 calculating the difference is more intuitive using LocalDate, LocalDateTime to represent the two dates 

    LocalDate now = LocalDate.now();
    LocalDate inputDate = LocalDate.of(2018, 11, 28);

    Period period = Period.between( inputDate, now);
    int diff = period.getDays();
    System.out.println("diff = " + diff);

(KOTLIN) For Difference between a constant date and current date (Joda)

You can use Days.daysBetween(jodaDate1,jodaDate2)

Here is an example:

        val dateTime: DateTime = DateTime.parse("14/09/2020",
            DateTimeFormat.forPattern("dd/MM/yyyy"))
        val currentDate = DateTime.now()
        //To calculate the days in between
        val dayCount = Days.daysBetween(dateTime,currentDate).days
        //Set Value to TextView 
        binding.daysCount.text = dayCount.toString()

DateTime  dt  = new DateTime(laterDate);        

DateTime newDate = dt.minus( new  DateTime ( previousDate ).getMillis());

System.out.println("No of days : " + newDate.getDayOfYear() - 1 );
