Question

If I have a two Dates in Java (Android) (Date1 and Date2), how can I know if the Date2 is within the same day of the Date1? (Note: not if the Date2-Date1 < 24 hours). Some examples (suppousing same month and year)

 Date1: day=14 hour=00:00           Date2: day=14 hour=00:00    --> Result TRUE
 Date1: day=13 hour=23:59           Date2: day=14 hour=00:00    --> Result FALSE
 Date1: day=14 hour=05:00           Date2: day=14 hour=00:00    --> Result TRUE
 Date1: day=14 hour=00:00           Date2: day=15 hour=00:00    --> Result FALSE

Thanks

Why don’t you use DateUtils?

You can directly invoke methods like isSameDay

if (DateUtils.isSameDay(date1, date2)) {
    System.out.println("Same Date");
} else if (date1.before(date2)) {
    System.out.println("date1 before date2");
} else {
    System.out.println("date1 after date2");
}

Check Apache DateUtils.
