The method, openly stated

The calculator works backwards from the date your caterer or venue needs final numbers, then subtracts buffer days for chasing non-repliers. For a multi-day wedding it assumes final counts ten days before the event and a deadline three weeks out; for a single day wedding, seven days and two weeks; for a small party, three days and one week. If your caterer's cutoff differs, shift everything to match it: the deadline should always sit a few days before the cutoff, never on it.

Frequently asked questions

How does the RSVP deadline calculator work?

It works backwards from your event date using standard planning buffers: the deadline sits two to three weeks before a wedding so there is still time to chase non-repliers before caterers need final numbers. The full method is stated in the section above.

When should RSVPs be due for a wedding?

Two to three weeks before the wedding for single-day celebrations, and about three weeks for multi-day weddings where each function has its own catering order.

When should RSVPs be due for a party or dinner?

About one week before the event is enough for small gatherings, with the reminder three days before that deadline.

How many reminders should I send?

One reminder a week before the deadline, plus one final short chase two days after it, recovers most missing replies. More than that turns reminders into pressure.

Rather not chase deadlines by hand?
