DateField Strange Behaviour

[moja_a]

When I set the Date "01 / 01 / 1500" in a DateField

The Result of MY code

       InputDate = dateField.getDate();
       stringItem1.setText(InputDate.toString());

The Result is 22/12/1499 which is 10 days before.
It does thae same for any Date before 1/1/1583

how can I get the correct Entered Date.

You may have problems with dates this far back in time. Ten days is the difference between the Julian Calendar (used in Europe before 1582) and the Gregorian Calendar (adopted in most Catholic parts of Europe since 1582, in the British Empire in 1752, in Russia in 1918 and Greece in 1923).

You must remember that, in Europe, it was different dates in different countries, between 1582 ad 1923. For any date between those years, you need to know what country you are (were) in before you can understand what date it was.

Certain dates simply never existed in many countries. In Italy, for example, 4th October 1582 was followed by 15th October 1582. The dates from 5th-14th of October 1582 never existed in Italy. However, the day that was 15th October 1582 in Italy was called 5th October 1582 in England.

The DateField you are using is treating any date before 1583 as Julian, and from 1583 onwards as Gregorian.

Does that make any sense?

Thanks For Info.

I Tried to add 10 days , To Get the The same Entered Date.

        InputDate = dateField.getDate();
        ResultCalnder.setTime(InputDate);
        ResultCalnder.add(Calendar.DATE, 10);

But There is an Error
cannot find symbol
symbol : method add(int,int)
location: class java.util.Calendar
ResultCalnder.add(Calendar.DATE, 10);

Calendar has no "add()" method.

Why do you want dates back in the 1500s?

I am trying to make an App to convert Calenders

I found this code works

        InputDate = dateField.getDate();
        long DateLong = InputDate.getTime();
        
            final long MILLIS_PER_DAY = 24 * 60 * 60 * 1000L;
            DateLong += 10 * MILLIS_PER_DAY;
            ResultCalnder.setTime(new Date(DateLong));
