Calculate days between two LocalDate objects in Java

You can use the ChronoUnit.DAYS enum to calculate the days between two LocalDate instances in Java. It provides the between() method to calculate the amount of time between two temporal objects:

// Create date instances
LocalDate startDate = LocalDate.parse("2022-08-30");
LocalDate endDate = LocalDate.parse("2022-11-16");

// Calculate the difference
long days = ChronoUnit.DAYS.between(startDate, endDate);

// Print days
System.out.println("Days between " + startDate + " and " + endDate + ": " + days);
// Days between 2022-08-30 and 2022-11-16: 78

The ChronoUnit enum class was introduced in Java 8 to represent individual date and time units such as day, month, year, week, hour, minutes, etc.

The between() method returns the difference in days as a negative number if the start is after the end date, as shown below:

System.out.println(ChronoUnit.DAYS.between(endDate, startDate)); // -78

You can also use the ChronoUnit enum to calculate the difference between two LocalDate objects in weeks, months, and years:

System.out.println(ChronoUnit.WEEKS.between(startDate, endDate)); // 11
System.out.println(ChronoUnit.MONTHS.between(startDate, endDate)); // 2
System.out.println(ChronoUnit.YEARS.between(startDate, endDate)); // 0
