A Day propriedade retornará um valor válido somente se a IsFixedDateRule propriedade for true .The Day property returns a valid value only if the IsFixedDateRule property is true.

O Day valor da propriedade corresponde ao valor do day parâmetro do CreateFixedDateRule método.The Day property value corresponds to the value of the day parameter of the CreateFixedDateRule method. Se seu valor for maior que o número de dias no mês da transição, a transição ocorrerá no último dia do mês.If its value is greater than the number of days in the month of the transition, the transition occurs on the last day of the month.

A Day propriedade indica o dia do mês em que uma regra de data fixa é aplicada (por exemplo, 15 de abril).The Day property indicates the day of the month on which a fixed-date rule is applied (for example, April 15). Por outro lado, a DayOfWeek propriedade indica o dia da semana em que uma regra de data flutuante é aplicada (por exemplo, o segundo domingo de novembro).In contrast, the DayOfWeek property indicates the day of the week on which a floating-date rule is applied (for example, the second Sunday of November).
