McDonald's typically starts serving lunch at 10:30 a.m. local time on weekdays. On weekends, the start time for lunch service may vary slightly, generally starting around 11:00 a.m., depending on the location. The lunch menu usually begins once the breakfast menu is no longer available, so the exact time can vary based on the restaurant and demand. For the most accurate lunch start time, it's best to check with your local McDonald's, but expect lunch to start around 10:30 a.m. on weekdays and 11:00 a.m. on weekends.
