How do you subtract two dates in Java?Brian L. Gorman
By converting a date to milliseconds. Once you have milliseconds, you can just subtract them and then again divide them by86400000 (milliseconds per day). This way you will get exactly how many days between two dates in Java. How will you get millisecond from a date in Java? by usingget...

Java两个⽇期间的天数计算 在Java中计算两个⽇期间的天数,⼤致有2种⽅法:⼀是使⽤原⽣JDK进⾏计算,在JDK8中提供了更为直接和完善的⽅法;⼆是使⽤第三⽅库。1、使⽤原⽣的JDK [java]1. private static long daysBetween(Date one, Date two) { 2. long difference = (on...
// Let's say we have two LocalDates, date1 and date2: LocalDate date1 = LocalDate.of(2021, 10, 6); LocalDate date2 = LocalDate.of(2022, 3, 7); // We can get the year for each object and then subtract the two years: long yearsBetween = date2.getYear() - date1.getYear...
