Announce your wedding! Save the dates are great for allowing guests to mark the occasion on their calendars well in advance. These are typically sent 12-18 months before the formal invitation, especially for destination weddings or events scheduled during busy times of the year, giving guests ample time to plan for travel, accommodations, and other arrangements. Save the Dates will help ensure that loved ones can prioritise the wedding and increase the likelihood of attendance, setting a tone of excitement for the upcoming celebration.
