How to Compare Dates in Java Ignoring Time?

How to Compare Dates by Ignoring Time

The java.util.Date class includes a time component, which can complicate comparisons between dates. To disregard the time portion, consider the following approaches:

Using Joda Time Library:

Joda Time provides a convenient solution:

DateTime first = ...;
DateTime second = ...;

LocalDate firstDate = first.toLocalDate();
LocalDate secondDate = second.toLocalDate();

return firstDate.compareTo(secondDate);

Or, for even greater simplicity:

return DateTimeComparator.getDateOnlyInstance().compare(first, second);

Using Calendar (Less Recommended):

If Joda Time is unavailable, you can create Calendar instances with the specified date and time zone and manually clear the time fields:

Calendar firstCalendar = Calendar.getInstance();
firstCalendar.setTime(first);
firstCalendar.set(Calendar.HOUR_OF_DAY, 0);
firstCalendar.set(Calendar.MINUTE, 0);
firstCalendar.set(Calendar.SECOND, 0);
firstCalendar.set(Calendar.MILLISECOND, 0);

Calendar secondCalendar = ... // Do the same for second date

return firstCalendar.compareTo(secondCalendar);
