      return events.where((event) {
        return isSameDate(
            event.start, now.add(Duration(days: normalizedIndex)));
      }).toList();
    case CalendarFormat.threeDays:
      return events.where((event) {
        return event.start.isAfter(
                startOfDay(now.add(Duration(days: normalizedIndex - 1)))) &&
            event.start.isBefore(
                endOfDay(now.add(Duration(days: normalizedIndex + 1))));
      }).toList();
    case CalendarFormat.week:
      return events.where((event) {
        return event.start.isAfter(
                startOfDay(now.add(Duration(days: normalizedIndex - 3)))) &&
            event.start.isBefore(
                endOfDay(now.add(Duration(days: normalizedIndex + 3))));
      }).toList();
