The reasoning behind these lead times is in RSVP deadline etiquette. To have the form close itself on the date, create a free RSVP page.
Questions people ask
- How does this RSVP deadline calculator work?
- Enter your event date and the type of event. It works backwards using the lead time each event type usually needs, and shows the reply-by date to print on the invitation plus the day to send your single reminder.
- Why is the deadline earlier than my caterer's cut-off?
- Because late replies are guaranteed. Setting the guest deadline about a week before the vendor's cut-off gives you time to chase the silent guests without missing the number that actually matters.
- Is my event date sent anywhere?
- No. The calculation runs entirely in your browser. Nothing is submitted, stored or logged, and no account is needed.
- Can the deadline enforce itself?
- In InviteFox, yes. Add the reply-by date to your event and the RSVP form closes on that date automatically, so you are not judging late replies one at a time.
