Java DayOfWeek

Learn to determine which day of the week is a given date in Java. The weekdays are considered all 7 days from Sunday, Monday till Saturday.

1. DayOfWeek Enum

DayOfWeek is an enum representing the seven days of the week – Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.

  • As it is an enum, it has ordinal values associated with each day. It is from 1 (Monday) to 7 (Sunday).
  • Some locales also assign different numeric values to the days, declaring Sunday to have the value 1, however, this class provides no support for this.
  • To get the numeric representation, use of getValue() is recommended.
  • This is an immutable and thread-safe enum.

2. Determining DayOfWeek from LocalDate

LocalDate class has method getDayOfWeek() which return the enum value representing that day of the week.

LocalDate today =;

System.out.println( today.getDayOfWeek() );				// SUNDAY
System.out.println( today.getDayOfWeek().getValue() );	// 7

Similar to LocalDate, other temporal classes also provide this method.

3. Localized Display

Use getDisplayName(TextStyle, Locale) to get the value of a day of the week in locale-specific manner.

DayOfWeek dayOfWeek =;

String displayName = dayOfWeek.getDisplayName(TextStyle.FULL, Locale.getDefault()); // Sunday

String displayNameInGerman = dayOfWeek.getDisplayName(TextStyle.FULL, Locale.GERMAN); // Sonntag

Happy Learning !!
