I'm getting married in May of next year, and I'm not really sure when to send out our save-the-dates. I don't want to send them out around the holiday season because I'm afraid they'll get lost in the shuffle of people's Christmas cards, etc... I feel like waiting until January is kind of late, because I want to make sure that those invited have plenty of notice. Is sending save-the-dates next month way too early? If so, when do you recommend I send them, and how long after should we send the formal invite?
