In many cultures, weddings are timed to occur on lucky days. in 2011, wedding planners from las vegas, nevada, to mumbai, india, knew long before the auspicious date of november 11th (11/11/11) that this would be one of their busiest days of the year, if not the century. because other dates would just not be as lucky for the blushing brides and grooms, and simply would not suffice, the wedding planners had to prepare all year for more weddings on this one date than on any other day throughout the year. this example illustrates the characteristic of services.
