Use java.time.LocalDate.datesUntil() method to define a range of consecutive days, which are represented as Stream<LocalDate> You can compare dates with LocalDate.isBefore, isEqual, isAfter methods. https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/time/LocalDate.html#datesUntil(java.time.LocalDate)
