Timing is always a big concern of any bride. I addressed an issue similar to this when meeting with a client last month. Enjoy!
Question: I've been busy with school, so I"m a bit behind with planning. Is five months before the wedding too late to send out save-the-dates?
Answer: It's cutting it close, but you can definitely still send them-especially if you already did all of the work and just need to address them! We typically suggest sending save-the-dates at least six months before the wedding, but since they're not required, you can do it whenever! There are really just two "rules" The first is to make sure that there's more than one month between when guests get the save-the-date and when they receive their invitation. The second is to send the save-the-dates early if you're having a destination event-at least six months before your wedding. You want to give people as much time as possible to book their trip. If you're marrying closer to home, a save-the-date tends to be more of an extra, so if you don't have the time to send them, don't worry. Spread the date by word of mouth instead.
