joda time - add weekdays to date

Question

Is it possible to add weekdays to joda time?

For instance, if current date is Friday 01/03, date + 1 should return Monday 04/03, rather than 02/03.

Answer 1

Be aware that iterating through adding N days one at a time can be relatively expensive. For small values of N and/or non performance sensitive code, this is probably not an issue. Where it is, I'd recommend minimizing the add operations by working out how many weeks and days you need to adjust by:

/**
 * Returns the date that is {@code n} weekdays after the specified date.
 * 

 * Weekdays are Monday through Friday.
 * 

 * If {@code date} is a weekend, 1 weekday after is Monday.
 */
public static LocalDate weekdaysAfter(int n, LocalDate date) {
    if (n == 0)
        return date;
    if (n < 0)
        return weekdaysBefore(-n, date);
    LocalDate newDate = date;
    int dow = date.getDayOfWeek();
    if (dow >= DateTimeConstants.SATURDAY) {
        newDate = date.plusDays(8 - dow);
        n--;
    }
    int nWeeks = n / 5;
    int nDays = n % 5;
    newDate = newDate.plusWeeks(nWeeks);
    return ( (newDate.getDayOfWeek() + nDays) > DateTimeConstants.FRIDAY)
            ? newDate.plusDays(nDays + 2)
            : newDate.plusDays(nDays);
