How far ahead should you open your booking calendar?

It is one of those questions that rarely sits on top of an actual decision. Your calendar is open until somewhere next year — but until exactly when, and why there, almost nobody still knows. Until an email arrives: "Can we already lock in the long weekend next spring?"

And it turns out the date is not open yet. Or worse, it is open, at the rate you entered two years ago and never touched again.

How far ahead you open is a real decision, with money on both sides of it. Below: what goes wrong at each extreme, a workable rule per property type, and how to roll the window forward once a quarter without losing half a day to it.

What you lose by opening too short

Most small hosts sit on the short side, usually without realising it.

You miss precisely the longer stays. Bookings that come in months ahead are rarely that single midweek night. They are the weekends with a reason behind them — an anniversary, a festival, a family gathering — and those are the two-, three- and four-night bookings. People who plan that far ahead also rarely book only to cancel later.

You are invisible at exactly the wrong moments. A guest searching for "July next year" who does not see you will not come back later to check whether you have opened up since. That search happens once.

You push guests into your inbox. "Call or email us for next year" sounds hospitable, but in practice it means answering by hand, blocking by hand, and a reservation that lives nowhere in your system until you enter it yourself.

What you lose by opening too far

The other side is less visible, but more expensive.

You sell high season at old prices. A calendar open eighteen months out with last year's rates sells your most expensive nights at last year's number. You notice once the booking is confirmed — and then you are stuck with it.

Your costs are not settled yet. Energy, cleaning, breakfast supplies and insurance all move. So does regulation: the Belgian VAT rate on accommodation went to 12% on 1 March 2026. Anyone who locked in a price a year earlier had not priced that change in. Selling far ahead always involves a small bet on your own cost base.

You block your own life. Closing days, renovations, a week away in low season: the further ahead you open, the greater the chance someone books exactly the weekend you did not yet know you needed. Cancelling a booking you accepted yourself costs you far more on the OTAs than the weekend is worth.

A workable rule

Do not think in terms of "until when", think in terms of a rolling window: a fixed number of months ahead that you move forward at fixed moments. As a guideline:

• City properties and classic B&Bs: 12 months. Your audience largely books within the year. Twelve months covers the public holidays, the events and the regular returning weekends, and your rates stay manageable.
• Holiday homes and coastal or rural properties: 14 to 18 months. People renting a whole house for a family or a group of friends plan further ahead. Having two summers in your calendar is not a luxury here.
• Properties that live off groups and events: 18 to 24 months. A family reunion or a wedding weekend gets fixed a year and a half to two years in advance. Without a long window you are simply not a candidate.

And then the condition that matters most, whichever number you land on: never open further than you have entered prices for. The calendar may only open once the season behind it has a rate. Do it the other way round and you are retroactively selling at your old prices.

Account for what the channels themselves do

Every channel has its own maximum and its own setting. Airbnb has an explicit booking window in the listing settings, with options up to roughly two years or "all future dates". Booking.com and Expedia work with their own horizon in the extranet. Those maximums shift occasionally, so check them once a year rather than relying on something you read a while back.

More important than the exact limit is this: if you work with a channel manager, only what exists in your own calendar gets pushed. A date that does not exist on your side lands nowhere. And the reverse trap is more common than you would think: availability that did get pushed, while your minimum stay and arrival rules for that period did not travel with it. The result is a single stray night in a holiday weekend, sold at a price you never signed up for. So open your minimum stay together with your availability, never afterwards.

The quarterly round: twenty minutes, four times a year

Make it a recurring appointment instead of a chore you postpone. Four fixed moments a year, the same five steps each time:

1. Roll the window three months forward. If your calendar is open until September next year, it becomes December.
2. Enter the prices for those new months first. Base rate, weekend rate, and the seasons you already know about. Only then do you open the availability.
3. Fix the known outliers straight away. Public holidays, local events, school holidays. See pricing for events and holidays — five minutes now saves a missed weekend rate later.
4. Block your own days. Closing periods and time off first, because that question otherwise always arrives too late.
5. Check your rules. Minimum stay, arrival and departure days, cancellation terms. For bookings that far out, a stricter policy or a deposit is reasonable: see the non-refundable rate.

Put those four moments in your diary now. The difference between a host who does this and one who does not is a full calendar with correct prices versus a calendar that is permanently three months behind.

How to handle this in BedFlow PMS

In BedFlow PMS you manage this from one calendar instead of channel by channel. You set up seasons and rate rules with a start and end date, adjust prices in bulk across a whole period, and only open availability for the months that actually have a rate underneath them. Availability, prices and restrictions are pushed to your connected channels in the same movement, so you never end up with nights open but no minimum stay attached. The documentation walks through setting up a season or a rate rule step by step.

In short

Pick a rolling window instead of an arbitrary end date: 12 months for a classic B&B, 14 to 18 for holiday homes, longer if you are after groups. Never open further than you have entered prices for, and always push your restrictions along with your availability. Roll the window forward four times a year in twenty minutes, and you will be selling next high season at next year's rates instead of last year's.
