Adjust dates
This recipe shows you how to adjust dates using the four main date adjustment conventions.
Whilst this recipe only shows adjusting a date, you can also adjust whole schedules using the same method, just pass a schedule instead of a date to the HolidayCalendar.adjust method.
For a recipe to create a schedule, click here.
// Create two new dates for
// Saturday 30 September and
// Sunday 1 October
Calendar date1 = ISDADateFormat.parse("2006/9/30");
Calendar date2 = ISDADateFormat.parse("2006/10/1");
// Use the default holiday calendar
// factory to provide us with a
// holiday calendar for weekends
HolidayCalendar weekends =
HolidayCalendarFactory.newInstance().
getHolidayCalendar("WE");
// Use the weekends holiday calendar
// to print out date1 and date2
// adjusted
System.out.println(
ISDADateFormat.format(date1)+
" PRECEDING "+
ISDADateFormat.format(
weekends.adjust(
date1,
BusinessDayConvention.PRECEDING
)
)
);
System.out.println(
ISDADateFormat.format(date1)+
" FOLLOWING"+
ISDADateFormat.format(
weekends.adjust(
date1,
BusinessDayConvention.FOLLOWING
)
)
);
System.out.println(
ISDADateFormat.format(date1)+
" MODIFIED PRECEDING "+
ISDADateFormat.format(
weekends.adjust(
date1,
BusinessDayConvention.MODIFIED_PRECEDING
)
)
);
System.out.println(
ISDADateFormat.format(date1)+
" MODIFIED FOLLOWING "+
ISDADateFormat.format(
weekends.adjust(
date1,
BusinessDayConvention.MODIFIED_FOLLOWING
)
)
);
System.out.println(
ISDADateFormat.format(date2)+
" PRECEDING "+
ISDADateFormat.format(
weekends.adjust(
date2,
BusinessDayConvention.PRECEDING
)
)
);
System.out.println(
ISDADateFormat.format(date2)+
" FOLLOWING"+
ISDADateFormat.format(
weekends.adjust(
date2,
BusinessDayConvention.FOLLOWING
)
)
);
System.out.println(
ISDADateFormat.format(date2)+
" MODIFIED PRECEDING "+
ISDADateFormat.format(
weekends.adjust(
date2,
BusinessDayConvention.MODIFIED_PRECEDING
)
)
);
System.out.println(
ISDADateFormat.format(date2)+
" MODIFIED FOLLOWING "+
ISDADateFormat.format(
weekends.adjust(
date2,
BusinessDayConvention.MODIFIED_FOLLOWING
)
)
);
