Promote an open night too early and you spend effort on guests who aren't shopping yet. Promote it too late and the night is already stale, and an empty night doesn't come back (it costs more than the nightly rate, as the real cost of an empty night works through). What decides it is how far ahead your guests book, and the public pages I checked can't tell you that for your property.
Measure your own median lead time from your last 12 months of bookings (the worked example uses ten made-up bookings), and use it to set when to start promoting an open night. I won't give you one universal number, because nothing I read supports one.
How far ahead do guests book a vacation rental?
There is no single answer: the two sources that define booking window describe the same interval, and the only figures I could check come from one page that doesn't reconcile its own figures (all checked 2026-11-04).
| Source | Definition given | What it states |
|---|---|---|
| Beyond Pricing, booking window versus booking pace article | Booking window is "how many days pass between the booking and the guest's arrival" | Separates it from booking pace, which "shows how quickly a specific set of dates is filling up" |
| Beyond Pricing, booking lead times trend alert | None: the page defines neither lead time nor booking window | "a 23% decrease in average booking lead times across the U.S." over the last 12 months, and 26 days against 31 days the year before |
| Key Data Dashboard, Average Booking Window glossary entry | (Arrival Date – Booked Date) / Guest Checkins, averaged over the selected period | A definition only: the days between when the guest made the reservation and the check-in date |
The first and third rows describe the same interval, from booking to arrival. The trend page's two figures don't match: the headline is 23%, but 26 days against 31 days is a fall of 5 days in 31, about 16%, and the page doesn't say why. I'm not picking one figure over the other or averaging them.
Why shouldn't I just borrow one of those numbers?
Because a benchmark is somebody else's average, here a U.S.-wide one. The two definitions may also count differently: Beyond Pricing's is about "the booking", Key Data's formula divides by guest check-ins, and I can't tell from the pages whether the two give the same figure on the same reservations.
An average is also the wrong summary here, because a few bookings made far ahead pull it up; the next section uses the median. Use public numbers to notice a direction, not to set a start date.
How do I measure my own median lead time?
Take every completed stay with a check-in in the last 12 months, count the days from booking to check-in, sort those numbers and take the middle one. A spreadsheet with two date columns is all you need.
- Which bookings. Select by check-in date, because selecting by booking date drops the long-lead stays that haven't happened yet. Leave out cancellations and owner blocks.
- Where the dates come from. Get the booking date from each channel's reservation export or your property management system.
- One number per booking. A week-long stay gets one lead time, not one per night.
- Median, not average. With an even number of bookings, average the middle two.
- Split by season, and by weekday versus weekend, if you have enough bookings. Check-in day is a rough proxy: a four-night stay from Thursday still covers a weekend, so count a stay as weekend if it covers a Friday or Saturday night. If a slice has only a handful, merge it with a neighbour, because one new booking can move a thin median a long way.
- Know what it misses. Your data holds only nights that booked, so it shows when guests who found you decided, not what guests would have done for a night that stayed empty. Treat the median as a starting point.
If you have the bookings, give holiday and event weekends (how to promote holiday weekends and local events) and the slow stretch after the holidays (how to fill January vacancies) their own rows.
What does that look like with ten bookings?
In this illustration the median lead time is 14 days and the average is 26.5 days, from ten hypothetical bookings. The lead times in days, sorted, are 2, 4, 6, 9, 12, 16, 21, 30, 55 and 110.
With ten values the middle falls between the fifth and sixth, 12 and 16, so the median is (12 + 16) / 2 = 14. The values add up to 265, so the average is 265 / 10 = 26.5; the 110-day booking pulls it to almost double the median.
Now split the same ten, counting a stay as weekend if it covers a Friday or Saturday night: six weekday stays (2, 4, 6, 9, 12 and 16) and four weekend stays (21, 30, 55 and 110).
| Slice (illustration only) | Bookings | Median lead time |
|---|---|---|
| All ten | 10 | 14 days |
| Weekday stays | 6 | 7.5 days, from (6 + 9) / 2 |
| Weekend stays | 4 | 42.5 days, from (30 + 55) / 2 |
The single 14 describes neither group. Use it for every night and the main push for weekends starts about four weeks late (42.5 minus 14 is 28.5 days). These ten are made up to show the mechanics; your weekdays could book earlier or later than your weekends, and a real year needs more bookings per slice.
When should I start promoting an open night?
Start the main push when the night is as far from check-in as your median lead time for that kind of night, and send a lighter first touch earlier. The logic: about half of your past bookings for that kind of night had been made by then, so the main push covers the half of your usual demand that is still to come. That is a reason to start, not a forecast that the night will book.
The multipliers below are my starting setting, not findings.
- First touch at about twice the median. One post and one email to past guests who agreed to hear from you, so little is wasted if guests aren't shopping yet.
- Main push at the median. Fresh posts and an email with the exact dates.
- Last push at about half the median. A final reminder with a booking link.
| Slice (illustration only) | Median | First touch | Main push | Last push |
|---|---|---|---|---|
| Weekday stays | 7.5 days | 15 days out | 7.5 days out | about 4 days out |
| Weekend stays | 42.5 days | 85 days out | 42.5 days out | about 21 days out |
Check two Airbnb settings before you commit to those dates. Airbnb's Help Center article on the availability window (checked 2026-11-04) says hosts can make the calendar available for "3, 6, 9, 12, or 24 months from today's date," so with only 3 months set, "a guest can only book up to 3 months from today." That caps how far ahead a guest can book, not when you may promote; it matters only if a first-touch lead is longer than the window.
Airbnb's hosting resources page (checked 2026-11-04) defines advance notice as the time hosts need between a booking and arrival, with options of same day, 1, 2, 3 or 7 days. If your advance notice is longer than the gap between your last push and check-in, guests may not be able to book inside it: with 7 days set, the weekday last push above, at about 4 days out, lands inside it. I checked only Airbnb's pages; other channels may have their own versions of both settings.
What if a night opens up late, like after a cancellation?
Go straight to the main push, because the clock starts when the night opens, not at your median. If a weekday night in the illustration opens up 5 days before check-in, it is already past its 7.5-day main push, so no first touch is left to send. How to fill last-minute Airbnb cancellations covers the steps.
How does Vacancy Vibe fit a lead-time rule?
Vacancy Vibe follows one lead-time number per property; it finds open nights on a schedule, so late openings surface on the next read. It connects to your booking calendar through its iCal link, detects open nights (an open night between two reservations that your own booking rules make unsellable is a gap night) and promotes them with social posts and email. Today publishing works to LinkedIn and X, and email campaigns are on every plan; Instagram, Facebook and Meta ads are pending Meta app approval.
The schedule is about every 10–15 minutes for most calendar feeds, and every 1–3 hours for Airbnb, Booking.com, Vrbo and Lodgify iCal links. The platform's own calendar refresh adds delay, which matters more close to check-in. Two property settings decide when it promotes. Detection only looks as far ahead as the look-ahead window (30 days by default, up to 365). With Auto-Post Mode set to Social and Auto-Generate Content on (both off by default), each open night's posts (and email, if that channel is on) are then scheduled for one time, a set number of days before the night (Default lead days, under Channels & Publishing: 7 by default, 1 to 30), or about two hours after scheduling if that day has already passed. So it can follow one median, not the weekday and weekend split above, and it can't reach a median past 30 days like the illustration's 42.5-day weekends. Schedule the other touches yourself.
FAQ
What is a vacation rental booking window?
Beyond Pricing defines it as how many days pass between the booking and the guest's arrival, which its FAQ counts as days of lead time. Key Data Dashboard defines Average Booking Window as the days from reservation to check-in, averaged over the selected period (both checked 2026-11-04).
Are guests booking closer to arrival than they used to?
One page says so, but its numbers don't match: Beyond Pricing's trend page reports a 23% decrease in average U.S. booking lead times over 12 months, yet its own 26 days against 31 days is about 16%, and it doesn't explain the gap (checked 2026-11-04). Compare your own median across two 12-month periods instead.
Should I use my average or my median lead time?
Median. A few bookings made far ahead pull an average up. In the ten-booking illustration above, the median is 14 days and the average is 26.5.
Is booking window the same as booking pace?
No. Per Beyond Pricing, booking window is the days between the booking and the guest's arrival, while booking pace is how quickly a specific set of dates is filling up (checked 2026-11-04).
Does my Airbnb availability window limit when I can promote?
It limits how far ahead a guest can book, not when you may promote. Airbnb's Help Center lets hosts choose 3, 6, 9, 12 or 24 months (checked 2026-11-04), so a promotion for dates beyond your setting can't produce an Airbnb booking yet. Advance notice is a separate setting at the other end, per Airbnb's hosting resources page (checked 2026-11-04).
