Java LocalDate toEpochDay() Method

Java toEpochDay() method is used to convert this date to Epoch Day. The Epoch Day count is a simple incrementing count of days where day 0 is 1970-01-01 (ISO). For example, we have a date 1970-01-11 then this method will return 10 epoch-days.

It does not take any argument but returns a long type value that represents the total epoch-days. The syntax of the method is given below.

It does not take any parameter.

It returns the Epoch Day equivalent to this date.

Let's take an example to get epoch days by using the toEpochDay() method. Here, we are using a date 1970-01-10 that holds total of 9 epoch days.

import java.time.LocalDate;
public class DateDemo {
    
    public static void main(String[] args){  
        
        LocalDate localDate = LocalDate.of(1970, 01, 10);
        System.out.println(localDate);
        long l = localDate.toEpochDay();
        System.out.println("Epoch Days : "+l);
    }
}

Output:

1970-01-10 

Epoch Days : 9

Let's take another example to understand the toEpochDay() method. Here, we have a long range date 2020-01-10 that returns a total of 18271 epoch days.

import java.time.LocalDate;
public class DateDemo {
    
    public static void main(String[] args){  
        
        LocalDate localDate = LocalDate.of(2020, 01, 10);
        System.out.println(localDate);
        long l = localDate.toEpochDay();
        System.out.println("Epoch Days : "+l);
    }
}

Output:

2020-01-10 

Epoch Days : 18271
