When does maccies breakfast end? Until when can you order the Mc Donalds breakfast menu?

Can you eat makkies breakfast all day long? Until when does the Mc Donalds serve breakfast menu, is there a specific period of the day for that? I do love their coffee and sandwiches early morning at weekdays, so I want to start my saturdays and sundays with maccies breakfast menu aswell but I fave a feeling they wouldn't serve it after 1pm.
