ee.Filter.calendarRange(start, end, field) | Filter |
Argument | Typ | Details |

start | Ganzzahl | Der Beginn des gewünschten Kalenderfelds, einschließlich. |
end | Ganzzahl, Standard: null | Das Ende des gewünschten Kalenderfelds (einschließlich). Standardmäßig wird derselbe Wert wie für „start“ verwendet. |
field | String, Standard: „day_of_year“ | Das Kalenderfeld, nach dem gefiltert werden soll. Folgende Optionen sind verfügbar: „year“, „month“, „hour“, „minute“, „day_of_year“, „day_of_month“ und „day_of_week“. |
