The ofEpochDay(long epochDay) method of LocalDate class in Java is used to obtain an instance of LocalDate from the epoch day count. Epoch day is 01-01-1970(DD-MM-YYYY). This is considered as a start of the epoch day. The method returns the LocalDate by adding the passed days into Epoch date i.e. 01-01-1970. Suppose 2 is passed as a parameter, the method will return 03-01-1970 (2 is added to ’01’ from the epoch day(DD)). Similarly, if 365 is passed then a whole new year will be added to the epoch date.
Syntax:
public static LocalDate ofEpochDay(long epochDay)
Parameters: This method accepts one parameter epochDay which is the conversion base.
Return Value: This method returns the localdate after conversion.
Exceptions: This method throws DateTimeException if the epoch day exceeds the supported date range.
Below programs illustrate the ofEpochDay(long epochDay) method in Java:
Program 1:
// Java program to demonstrate// LocalDate.ofEpochDay(long epochDay) method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // Create LocalDate object        LocalDate localdate            = LocalDate.ofEpochDay(100);          // Display full date        System.out.println("Date: "                           + localdate);    }} |

Program 2:
// Java program to demonstrate// LocalDate.ofEpochDay(long epochDay) method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // Create LocalDate object        LocalDate localdate            = LocalDate.ofEpochDay(365);          // Display date        System.out.println("Date: "                           + localdate);    }} |
