Para compensar la diferencia entre el año natural y el tiempo real que la Tierra gira alrededor del sol o en tiempo real que la luna gira en torno a la tierra, un año bisiesto tiene un número diferente de días de un año de calendario estándar.To make up for the difference between the calendar year and the actual time that the earth rotates around the sun or the actual time that the moon rotates around the earth, a leap year has a different number of days from a standard calendar year. Cada Calendar implementación define los años bisiestos de manera diferente.Each Calendar implementation defines leap years differently.

Notas a los desarrolladores de herederos

La clase derivada debe admitir CurrentEra cuando se pasa como el era parámetro.The derived class must support CurrentEra when it is passed as the era parameter. Una manera de admitir CurrentEra está reemplazando el valor almacenado en Eras [0], que es el valor de la era actual del calendario.One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
