Comentarios

Para compensar la diferencia entre el año natural y el tiempo real que la tierra gira alrededor del sol o la hora real en que la luna gira alrededor de la tierra, un año bisiesto tiene un número diferente de días a partir de un año natural estándar. Cada Calendar implementación define años bisiestos de forma diferente.

Un día bisiesto es un día que solo se produce en un año bisiesto. Por ejemplo, en el calendario gregoriano, el día 29 de febrero es el único día bisiesto.

Un día bisiesto es un día que solo se produce en un año bisiesto. Por ejemplo, en el calendario gregoriano, el día 29 de febrero es el único día bisiesto.

Notas a los implementadores

La clase derivada debe admitir CurrentEra cuando se pasa como era parámetro . Una manera de admitir CurrentEra es reemplazarla por el valor almacenado en Eras[0], que es el valor de la era actual del calendario.
