Every event has a sending window, and most RSVP problems trace back to missing it. Send too early and the invitation gets filed away and forgotten; send too late and calendars are already full. This guide gives you the right send date for 18 kinds of events, the RSVP deadlines that make caterers happy, and what to do when you are already behind schedule.
Timing is also easier to get right when the sending is instant. Greenvelope is a digital invitation platform where invitations with built-in RSVP tracking arrive the moment you send them, can be scheduled in advance, and follow up with guests automatically, so the windows below become a calendar entry instead of a project.

Wedding Invitations and the RSVP Deadline
Send wedding invitations 6 to 8 weeks before the wedding, with the RSVP deadline 3 to 4 weeks before the day. That deadline is the number everything else depends on: it should land about one week before the caterer’s final count is due. Once the send date is set, our wedding invitation wording guide covers what the invitation should say, line by line.
Destination weddings stretch every window. Invitations go out 10 to 12 weeks ahead, save the dates 8 to 12 months ahead, and the RSVP deadline moves to 6 weeks before the day, since travel bookings and headcounts both need longer runways.
Save the Dates: Who Actually Needs One
Save the dates exist for events guests must plan around: weddings, destination celebrations, milestone birthdays with traveling guests, and large corporate events where registration or sponsorship depends on early commitments. Galas and fundraisers typically circulate a save the date 3 to 6 months out. For everything else, a well-timed invitation does the whole job, and milestone birthdays deserve 4 to 6 weeks, with a save the date a few months out if guests will travel.
Parties, Showers, and Everything Casual
Most non-wedding events follow one rule: 3 to 4 weeks of notice for anything guests should prioritize, and 1 to 2 weeks for anything casual. Kids’ parties run shorter because family calendars are decided week to week, and holiday parties run longer because December fills up by Thanksgiving. When in doubt, err earlier and set the RSVP deadline generously ahead of your own real cutoff.
The Reminder Cadence
Whatever the event, plan on two nudges: a friendly reminder about one week before the RSVP deadline, and a brief final note one or two days before it, or immediately after it passes. Send both only to guests who have not yet replied. Greenvelope schedules these reminders automatically and sends them only to non-responders, which keeps the cadence polite without any manual tracking.
Already Behind Schedule? The Recovery Plan
A late invitation beats no invitation. Send digitally today rather than waiting for anything, use text message delivery for speed, shorten the RSVP window to what you genuinely need, and add a personal note acknowledging the timing once. Guests forgive lateness far more readily than they forgive finding out too late to come.
Frequently Asked Questions
How far in advance should you send party invitations?
For most parties, send invitations 3 to 4 weeks before the event: adult birthdays, graduations, and housewarmings all fall in that window. Kids’ parties need 2 to 3 weeks, casual dinner parties 1 to 2 weeks, and holiday parties 4 to 6 weeks, since December calendars fill early. When many guests will travel, add a week or two to any of these.
How far in advance should you send wedding invitations?
Send wedding invitations 6 to 8 weeks before the wedding, or 10 to 12 weeks for a destination wedding. Set the RSVP deadline 3 to 4 weeks before the day so your caterer’s final count has breathing room.
How far in advance should you send save the dates?
For weddings, 6 to 8 months before the day, or 8 to 12 months for destination weddings. Large corporate events, galas, and fundraisers circulate save the dates 3 to 6 months ahead.
When should you send a save the date for a corporate event?
Send a save the date 3 to 6 months ahead for galas, fundraisers, and conferences, since sponsorships, table sales, and registration depend on early commitments. Smaller corporate events such as client dinners and holiday parties do not need one; send the invitation 2 to 6 weeks ahead instead.
When should you send out birthday party invitations?
Give 3 to 4 weeks of notice for an adult birthday and 2 to 3 weeks for a kids’ party. Milestone birthdays deserve 4 to 6 weeks, with a save the date a few months out if guests will travel.
Do you send save the dates for a birthday party?
Usually no. Save the dates are optional for birthdays and worth sending only for milestone celebrations where guests will travel. In that case, send the save the date 2 to 3 months ahead and follow with the invitation 4 to 6 weeks before the party.
Is two weeks enough notice for a party?
For casual gatherings, yes: dinner parties and housewarmings work well with 1 to 2 weeks of notice. For events guests should prioritize, such as milestone birthdays or showers, 3 to 4 weeks or more is the safer window.
When should you send corporate event invitations?
Client dinners need 3 to 4 weeks of notice, corporate holiday parties 4 to 6 weeks, and conferences 8 to 12 weeks, with save the dates 3 to 6 months ahead for registration-driven events.
When should you send holiday party invitations?
Send holiday party invitations 4 to 6 weeks ahead, since December calendars fill by Thanksgiving. For early-December dates, a save the date in October protects the evening.
How long should you give guests to RSVP?
Work backward from your caterer’s real cutoff and set the RSVP deadline about one week before it. For weddings that means 3 to 4 weeks before the day; for casual events, 2 to 3 days before is enough.
What if I’m sending invitations late?
Send digitally today, use text delivery for speed, shorten the RSVP window to what you genuinely need, and acknowledge the timing once with a warm personal note. A late invitation beats no invitation every time.
