A save the date does one job: it gets your event into people's diaries before something else does. It isn't the invitation, it doesn't need every detail, and it definitely doesn't need to be expensive. But send it at the wrong time, or to the wrong people, and you'll create problems you have to untangle later.

Here's what to send, when, who to send it to and what to say, whether you're planning a wedding, a big birthday, a reunion or a weekend away.

Do you actually need one?

Not every event needs a save the date. They're most useful when:

For a local party six weeks away, skip it and send the invitation. For a wedding, a milestone birthday abroad or a big family reunion, a save the date is well worth doing.

When to send them

Timing depends on the type of event and how much effort it takes to attend.

Weddings

Around six to twelve months before the day is the usual window. Closer to eight months is a comfortable middle ground for most UK weddings. Go earlier if your date is in peak summer, when guests may have several weddings in the diary.

Parties and celebrations

For a milestone birthday, anniversary, christening or reunion, two to four months is usually plenty. People don't need as much notice for an evening party, but a heads-up before the invitation helps if the date is significant.

Destination and weekend events

If guests need to fly, book several nights away or arrange childcare for a weekend, give them as long as you possibly can. Nine to twelve months is sensible, and some people send them even earlier. Flights and accommodation are easier to arrange the further ahead they're booked.

Who gets one

This is the golden rule: only send a save the date to people you are definitely going to invite. Once someone has one, they're on the list. Taking it back later is miserable for everyone.

That means you need a fairly settled guest list before you send them. If you're not sure about a group, such as work colleagues or plus-ones, hold off on them until you've decided. It's fine to send save the dates to your certain guests only and leave the maybes for the invitation stage.

Be clear about plus-ones and children from the start. If the save the date is addressed to "Tom and Sophie", Tom and Sophie are invited. If it says "The Patel Family", people will assume the children are too.

What to say

Keep it short. A save the date needs:

  1. Your names, or whose event it is
  2. The date
  3. The town or area, and the venue if it's confirmed
  4. A line saying an invitation will follow
  5. A link to your event website, if you have one

That's genuinely it. Save the timings, menus and dress code for the invitation.

Digital or printed?

Both are perfectly acceptable now. Choose based on your guests and your budget.

Printed save the dates feel special and often end up stuck to the fridge, which is exactly where you want them. They suit formal weddings and older relatives who prefer something through the letterbox. The downsides are cost, postage, the time it takes to gather addresses, and the fact that you can't update them.

Digital save the dates are quick, free or cheap, and easy to send to people abroad. You can link straight to a website with more information, and you know when they've gone out. They're ideal for parties, reunions and anything with a younger guest list.

Plenty of people do both: digital for most guests, and a handful of printed cards for grandparents and anyone not keen on email. On Every Gathering you can send Save the Dates by email from the same place you'll later send invitations, so your guest list only needs entering once.

A few common mistakes

One last thing

A save the date is the first thing your guests see of your event, so let it sound like you. Formal, playful or somewhere in between, the only thing it really has to get right is the date. Everything else can wait for the invitation.
