Duration between two dates Java [duplicate]

I have tried many things but this but cant find any help

Do these "many things" include consulting the javadoc where you would find that:

// assuming both dates are in d1 and d2 Duration duration = Duration.between(d1, d2); long hours = duration.toHours(); 

Hope that helps.

java.time

import java.time.Duration; import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; public class Main { public static void main(String[] args) { DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); LocalDateTime dt1 = LocalDateTime.parse("2020-04-03 01:29:27", formatter); LocalDateTime dt2 = LocalDateTime.parse("2020-04-03 01:29:37", formatter); System.out.printf("%.4f Hour(s)", Duration.between(dt1, dt2).toSeconds() / 3600.0); } } 

Output:

0.0028 Hour(s)
