Have you ever wondered if there is a perfect time to send out invitations? Well, it’s always exciting planning a party. But you want to give your guests ample time to save the date. For more casual events like a bridal shower, a sweet sixteen, a baby’s birthday, a cocktail party, send your invitations out 3-4 weeks ahead of time. If you are planning a formal event such as a wedding, bar/bat mitzvah or a major charity event, you should send the invitations out approximately 10 weeks ahead of time! Remember to include a reply card or reply phone number so they can easily reply to you regarding their attendance.
