Tell us what’s happening:

Can’t understand why in some test the result exced the 12 hour and in other cases the result restart the 12 hour to 00:00. For example, for an initial time of 11:49PM and an additional time of 00:05 the expected result is 12:04AM (instead of 00:04AM). In other test the initial time is 8:16PM with an additional time of 266:02 (19 days and 10:02) and in this case the expected result is 6:18AM instead of 18:18AM. Can someone help me?

Your code so far

    start_minutes = int(start_time[1])

    # Duration parameters
    duration_splitted = duration.split(':')
    duration_hours = int(duration_splitted[0])
    duration_minutes = int(duration_splitted[1])
    
    hours_left = 0
    days = 0
    if duration_hours >= 24:
        days = duration_hours // 24
        hours_left = duration_hours % 24
    else:
        hours_left = duration_hours

    final_hour = start_hour + hours_left

        new_time += ', ' + DAYS_ON_WEEK[final_day][0].upper() + DAYS_ON_WEEK[final_day][1:]

    if days == 0 and ampm_changed and ampm == 'AM':

    elif days == 1:

    return new_time

print(add_time('11:59 PM', '24:05', 'Wednesday'))
