If @{method} is 0, the default, the MS Excel (tm) US method will be used. This is a somewhat complicated industry standard method where the last day of February is considered to be the 30th day of the month, but only for @{start_date}.
@{metodoa} 0 bada (balio lehenetsia), MS Excel (tm)(r)en metodo estatubatuarra erabiliko da. Industriako metodo estandar hau konplexu samarra da, otsaileko azken eguna hilaren 30tzat jotzen baita, baina soilik @{hasiera_data}(e)rako.
