# Guesty booking window beyond 12 months

Your booking calendar stops at 12 months, even though you want guests to be able to book further out.

**Why this happens.** Two settings control how far out guests can book on a HomeRunner site connected to Guesty. Both must be updated together to see the full extended window.

**Guesty listing booking window.** Each listing has its own booking window inside Guesty. HomeRunner reads that value from Guesty for every listing and never shows dates beyond it. Go to each listing's **Availability** settings in Guesty and confirm the booking window is set to the longer period you want. Your site picks up the new value on the next sync.

**HomeRunner calendar horizon.** HomeRunner pulls calendar data from Guesty up to a horizon that defaults to 12 months per connection. Even if Guesty is serving dates further out, your site treats anything beyond that horizon as unavailable. This change cannot be made from your account settings. Contact support and ask them to raise the calendar horizon on your connection to match the number of days you want. The maximum HomeRunner supports is 24 months (730 days). Once the horizon is updated and a full calendar sync runs, the additional dates should appear on your site.

**Booking Engine setting.** If your site also has a **maximum calendar days** setting in the **Booking Engine** settings, make sure that value is at least as large as the window you want to display.

Because HomeRunner always respects the Guesty listing value, raising the HomeRunner horizon alone will not help if your listings in Guesty are still set to 365 days.

Still stuck? [Contact the HomeRunner team](https://homerunner.io/contact/) with your site address and what you tried, and we take it from there.
