public class EventDateGenerator {
    public static void main(String[] args) {
        String input = "Occurs every 2 weeks from 28 Aug 2023 till 28 Oct 2023 on friday and monday";
        List<LocalDate> eventDates = generateEventDates(input);
        
        for (LocalDate date : eventDates) {
            System.out.println(date.format(DateTimeFormatter.ofPattern("dd MMM yyyy")));
        }

        List<LocalDate> eventDates = new ArrayList<>();

        String[] parts = input.split(" ");

        LocalDate startDate = LocalDate.parse(parts[5] + " " + parts[6] + " " + parts[7], DateTimeFormatter.ofPattern("dd MMM yyyy"));
        LocalDate endDate = LocalDate.parse(parts[11] + " " + parts[12] + " " + parts[13], DateTimeFormatter.ofPattern("dd MMM yyyy"));
        
        String[] daysOfWeek = parts[16].split("and");

        for (LocalDate date = startDate; !date.isAfter(endDate); date = date.plusWeeks(interval)) {
            for (String dayOfWeek : daysOfWeek) {
                DayOfWeek targetDay = DayOfWeek.valueOf(dayOfWeek.trim().toUpperCase());
                if (date.getDayOfWeek() == targetDay) {
                    eventDates.add(date);
                    break;
                }
