When to send save the dates

A dated path from save-the-dates to the invitation mailing and the RSVP deadline, with the ranges publishers actually give.

Send save-the-dates once the date and the city are real, then mail invitations about 6 to 8 weeks before the wedding, and set the reply date about 4 weeks before. Those three marks are the spine. The ranges around them depend on travel.

Save-the-dates, from the publishers that state a range:

• Emily Post puts "address and send save-the-date notices" in the 3 to 6 months before the wedding, or earlier.
• Shutterfly says most couples send them about 6 to 8 months before. Local weddings: 4 to 6 months. Destination weddings: 8 to 12 months. Holiday weekends or international travel: closer to 9 to 12 months.
• Shutterfly calls 3 months late rather than early, and says most couples send them at least 4 to 6 months before.

Invitations:

• Emily Post says to assemble and mail wedding invitations 6 to 8 weeks prior to the wedding date.
• The Knot gives the same mailing window, 6 to 8 weeks before, and says to have the invitations in hand at least 10 weeks before so you are not still waiting on a printer.
• Couples whose first mailing is the invitation itself get a different window from The Knot: 6 months before when the engagement is a standard length (it cites 14 months), and 3 months before for a short engagement.
• For a destination wedding, The Knot says mail invitations 8 weeks ahead if save-the-dates already went out. Its reply-date guide says send destination invitations closer to 10 or 12 weeks before. Use the longer of those two if guests are booking flights.

Replies:

• The Knot says wedding RSVPs should be due at least 4 weeks before the wedding, and no later than 2 weeks before. The sweet spot it names is 3 to 4 weeks. It also assumes invitations go out between 6 and 10 weeks before.

Send a save-the-date only to someone who will also get an invitation. Shutterfly says everyone who receives a save the date should also receive a wedding invitation, and to send save-the-dates only to guests you are definitely planning to invite.

What each piece is for

A save-the-date holds the date and the place so people can book travel and ask for time off. It does not ask for a meal, a plus-one decision, or a yes. Emily Post lists it as a notice you send if you need it, not as a required card. A local Saturday with a guest list that already lives nearby can go straight to invitations. A holiday weekend, a destination, or a room block is why the earlier card exists.

The invitation is the formal ask. The Knot warns that mailing it too early, over 12 weeks out, leaves people unsure of their schedules, so replies change later. The 6 to 8 week mailing is the compromise: long enough to clear a calendar, short enough that a yes is still a yes.

Paper replies need the longer end of that window. The Knot says to stick closer to 8 weeks when the reply card has to travel back by mail, and that a digital reply can sit closer to 6 weeks. Mail every invitation at the same time, including the ones for out-of-town guests, as The Knot advises.

One calendar, three deadlines

Work backward from the wedding date. The reply date comes first in the planning, even though it is the last date guests see.

1. Ask the caterer and the venue which date they need a headcount. The Knot has you share that final count around the 2 week mark. If a vendor needs the number sooner, your reply date moves earlier than the etiquette sweet spot, not later.
2. Set the reply date about 4 weeks before the wedding, inside the 3 to 4 week band, and never past 2 weeks before.
3. Mail invitations 6 to 8 weeks before, which leaves guests a few weeks between the envelope and the reply date. Have the suite at home at least 10 weeks before.
4. Send save-the-dates in the band that matches travel: 4 to 6 months for a local party, 6 to 8 months for most weddings, 8 to 12 months when people must book flights. Emily Post's 3 to 6 month line, or earlier, is the floor, not a reason to wait if travel is involved.

Park those dates on the wedding planning checklist next to the caterer deadline. After replies close, the next guest job is the table list in how to make a wedding seating chart.

The Guest list and RSVP tracker is a digital ZIP with no physical goods: a separate blank workbook, a fictitious worked-example workbook, and pen-filled task pages in Letter and A4, with capacity for 1,000 individual people. It turns household replies into clear meal, seat and follow-up decisions. It offers no bank connection, payments, invitation sending, automatic seating or jurisdiction-specific advice. The addresses and the yeses can live in that one place while the cards are out. This shop sells the tracker, not the save-the-dates or the invitations.

A Saturday on October 9, 2027 (illustrative)

The date is invented so the arithmetic is visible. Half the guests would fly, so the save-the-date band in use is Shutterfly's destination range, not the local one, and the invitation mailing uses the longer destination window: closer to 10 or 12 weeks, not 8.

October 9 minus 84 days is July 17, which is 12 weeks, the longer end of the 10 to 12 week destination window. The 10-week in-hand floor would fall on July 31, which is after that mailing, so the suite has to be home by July 17. Minus 28 days is September 11. Minus 14 days is September 25. February 9 is eight months before October 9. The invitation rows do not use the 8 week mark. Each other row uses a range named above. Nothing in the table says a guest will actually reply on time.

What the ranges cannot promise

A published window is not a promise that every guest will answer. The Knot still has you nudge people who have not replied, about a week after the deadline, and to plan on chasing stragglers at least 2 weeks before the wedding. A short engagement compresses the save-the-date band; send the notice as soon as the venue and the list are confirmed, or let the invitation do both jobs and use the 3 month invitation mark for that short case. For guests overseas, The Knot adds an extra week or two for shipping. Ask the stationer how long the print run takes before you promise yourself the 10 week in-hand date.
