So this is how my code looks like

cropref.child(mycrop.name).push({
                          cropname:mycrop.name,
                          croplocation:mycro

    You need to convert the date first in your Format. You can use SimpleDateFormatFormat for that.

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

    Now you can easily format your date to this format

    String mynewdate = sdf.format(mycrop.plantdate.getTime());
    

    The Output for today would be:

    2016-11-27
    

    Of course you can reverse that back to a Calendar. I do it this way:

     public static Calendar fromStringtoCalendar(String datestring){
        int year =  Integer.valueOf(datestring.substring(0, 4));
        int month =  Integer.valueOf(datestring.substring(5, 7)) -1;
        int day =  Integer.valueOf(datestring.substring(8, 10));
        Calendar calendar = Calendar.getInstance();
        calendar.set(year, month, day);
        return calendar;
    }
