RSVP deadline calculator
A useful deadline leaves time to follow up with missing households before you commit to a headcount.
Where the deadline comes from
The deadline is the event date minus the vendor lead time and the number of days the host wants for follow-up.
Move the date earlier when a venue or caterer needs a firm count sooner.
Give guests a clear reply date
Put the deadline on the invitation so it does not get lost in follow-up messages.
