As soon as you confirm your wedding date and finalize your guest list, you are free to send out your Save the Dates! This will give people time to plan around your event. The reason why you want to wait to send out your actual wedding invites out 2-4 months before the wedding is because peoples plans change. Even though family and friends might love you and your partner a lot and want to celebrate with you, it can be hard to RSVP for a wedding a year in advance. And even if you send out invites a year in advance but with an RSVP date a month or two before the wedding, people will forget! So, remember this rule: Save the Dates go out as soon as your details are finalized. Wedding Invites can go out 2-4 months before your wedding date (or you could stretch to 5-6 if you really wanted!).
