Save-the-date announcements, giving advance notice of an upcoming wedding or other social event, can be very helpful to guests who must make travel plans or when the wedding or event will be held at a time when there may be conflicts with other activities, such as on major holiday weekends. They are especially useful for alerting guests about a destination wedding.

 

Save-the-date announcements are usually mailed from three to four months prior to the wedding or event, but they may be mailed earlier for a destination wedding at a distant location.  Announcements can be sent to all guests or only those who need more time to plan.  Be sure that everyone who receives a save-the-date also receives an invitation.
