Duration vs Period in Java 8

Both classes can be used to represent an amount of time or also measure the difference two dates.
How to use both in different situations?

• date-based value (Period): check whether days of period is over setting.

  LocalDate localDate = java.time.LocalDate.parse(matcher.group(1), DATE_TIME_FORMATTER);
  long days = Period.between(localDate, java.time.LocalDate.now()).getDays();
  
  return (days >= 5);
  

• time-based value (Duration): check an interval of time in seconds or nanoseconds.

    Duration.between(startTime, LocalTime.now()).getSeconds();
