How the Wedding Planning Deadline Calculator works
Each date is counted back from the wedding day using a common planning timeline: about 12 months for the venue and caterer, 8 months for save-the-dates, 8 weeks for mailing invitations, 4 weeks for the RSVP deadline, 2 weeks for the final headcount, and 10 days for the seating chart. Popular venues and dates can book out more than a year ahead, while a small wedding may need much less time. Marriage license rules, waiting periods, and the time it takes to get one differ a lot by place, so check with the local office early. Example: with Wedding date 2027-12-11, the result is Book the venue and caterer by = Friday, December 11, 2026; Send save-the-dates by = Thursday, April 15, 2027; Mail invitations by = Saturday, October 16, 2027.
