I am trying to check if a particular date falls within a certain date range. I came across Joda Time interval in Java. But it works as end time exclusive.

So is there an alternative which functions as end time inclusive

    What's your exact use case? Can you describe it a little more in detail? Or could you show us the code with joda that doesn't do what's desired? – deHaar Jun 14 '21 at 10:37

    See this answer: https://stackoverflow.com/a/13584000/8621733 Strict `<` can be negated to `>=` so this might be useful. – Artúr Manó Marschal Jun 14 '21 at 10:41
  • Does your date have year, month of year and day of month only or are you talking about a `java.util.Date`? – deHaar Jun 14 '21 at 10:54

java.time

I recommend you use modern Date-Time API*.

Quoted below is a notice at the home page of Joda-Time:

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project.

You can use !date.isAfter where date is a reference to LocalDate e.g.

import java.time.LocalDate;

public class Main {
    public static void main(String[] args) {
        LocalDate start = LocalDate.of(2021, 5, 10);
        LocalDate end = LocalDate.of(2021, 6, 10);
        for (LocalDate date = start; !date.isAfter(end); date = date.plusDays(1)) {
            // ...
        }
    }
}

Learn more about the modern Date-Time API from Trail: Date Time.

* For any reason, if you have to stick to Java 6 or Java 7, you can use ThreeTen-Backport which backports most of the java.time functionality to Java 6 & 7. If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8+ APIs available through desugaring and How to use ThreeTenABP in Android Project.

    Solid Answer. Further tip: The [`LocalDateRange`](https://www.threeten.org/threeten-extra/apidocs/org.threeten.extra/org/threeten/extra/LocalDateRange.html) class in the [*ThreeTen-Extra*](https://www.threeten.org/threeten-extra/) library has methods to treat the ending as inclusive, using "closed" terminology, as in full-closed versus half-open. But I recommend always working with half-open to keep your logic consistent. I have seen many miscommunications amongst businesspeople regarding fully-closed versus half-open. And, using half-open enables time spans that neatly abut. – Basil Bourque Jun 14 '21 at 21:12
