There are different calendar systems in the world. Let’s write the Java 17 release date in the systems known to Java.

import java.time.LocalDate; import java.time.chrono.Chronology; public class CalendarSystems { void main() { LocalDate java25release = LocalDate.of(2025, 9, 16); Chronology.getAvailableChronologies().stream() // .sorted() // .map(c -> c.date(java25release)) // .forEach(IO::println); } }
