It is recommended that you start planning your wedding a year in advance, especially if you are planning a large wedding or a wedding abroad. Destination weddings mean guests will probably need to book flights and accommodation, as well as request holidays in advance. If you are planning a small, local wedding, on the other hand, then you have a little more flexibility and can probably start your planning 6 to 10 months in advance. Nonetheless, it's always a good idea to give guests enough time to save your date and look for venues and other suppliers well in advance to ensure you get your first choice.
