Class BusinessDayAdjuster

  • All Implemented Interfaces:
    TemporalAdjuster
    public class BusinessDayAdjuster
extends Object
implements TemporalAdjuster
    A TemporalAdjuster that adds or subtracts a specified number of business days to a date.

    A business day is a date that is not a weekend or in the list of holidays.

    LocalDate now = LocalDate.now(); LocalDate nextBusinessDay = now.with(BusinessDateAdjuster.addWorkDays(1));

    You can also use it with a Calendar object via the static helper methods.

    Calendar now = Calendar.getInstance(); Calendar nextBusinessDay = BusinessDateAdjuster.adjustCalendar(now, 1);
