Save the Dates
Save the dates are all about announcing your wedding date to loved ones — and making sure they mark it on their calendars. Aside from your date, you'll want to include the name of you and your sweetheart, the venue (if it's already booked) and the location. You can also let guests know that they can expect an invitation in the post soon by adding a short note: ‘Formal invitation to follow’.
We recommend you send them out around 6–8 months before your wedding date. Planning a destination wedding? You'll want to give guests a bit more notice — 9–12 months in advance is generally the sweet spot.
That's up to you. A save the date can sometimes serve as both an announcement and an invitation. This will depend on the format and wording of the save the date card. Typically, a save the date is only meant to inform guests that you're getting married (yay!) and that they should hold the date for the occasion (hence the name). However, some couples may choose to design their save the dates in a way that also functions as the formal invitation, including more details about their big day like accommodation or transportation. This approach could work well for a more casual or intimate wedding, where a separate invitation might not be needed.
Typically, no. Save the dates shouldn't be sent any earlier than 6 months before the wedding date, while invitations go out 6 to 8 weeks before.
