McDonald's breakfast menu generally starts serving from the time the local restaurant opens. For many locations, especially in the U.S., this can be as early as 5:00 or 6:00 AM, particularly in 24-hour restaurants where breakfast often starts at 5:00 or 6:00 AM. The breakfast menu is typically available until around 10:30 or 11:00 AM local time, with some variation depending on the location and franchise decisions. In summary:
- Breakfast start time: from the restaurant opening (often 5:00 or 6:00 AM in 24-hour restaurants)
- Breakfast end time: typically between 10:30 and 11:00 AM
Local variations may occur, but this is the common practice at most McDonald's restaurants.
