What is the update period?
The update period controls how far ahead (in days) Channel Manager sends your rates, availability, and restrictions to your connected booking channels. It is also sometimes called your booking window.
By default, Channel Manager sends updates 400 days into the future. You can increase this up to a maximum of 750 days.
💡 The Channel Manager calendar extends 750 days into the future, but each connected channel has its own maximum update period limit. Updates sent beyond a channel's maximum will not sync to that channel.
How is the update period calculated per channel?
The number of days actually sent to each channel depends on whichever is lower: your property update period, or the channel's own maximum update period.
For example, if your property update period is set to 400 days:
Booking.com (maximum: 572 days) receives 400 days of updates — limited by your property setting, not Booking.com's limit.
A channel with a maximum of 220 days receives 220 days of updates — limited by that channel's maximum, not your 400-day setting.
To send Booking.com updates for the full 572 days, you would need to increase your property update period to at least 573 days in Property Settings.
How to view each channel′s update period
You can see each channel's maximum update period in two places:
Under the Channels tab
In the inventory grid
To see the current number of days being sent to a specific channel, click on any channel rate for that channel.
💡 Your current update period for a channel may be different from that channel's maximum update period. To see the current number of days being sent to a specific channel, click on any channel rate for that channel.
How to change your property update period
Your property update period is set to 400 days by default when you first set up Channel Manager.
To change how many days ahead updates are sent to your channels:
Go to My Apps > Channel Manager.
Click your property name in the top right corner and select Property Settings.
In the General tab, find the Update period field.
Select your preferred update period from the drop-down menu.
💡 Little Hotelier's Front Desk calendar, used for manual and direct bookings, has an update period of 716 days (around 24 months / just under 2 years) into the future. This setting cannot be changed.
Update period that will be sent for each channel
The actual number of days (update period) sent to each channel is determined by whichever is lower: your property update period OR the channel's maximum update period. In other words, the shortest timeframe wins.
For example, if your property update period is set to 400 days, and your channels' limits are:
Booking.com - accepts up to 572 days
Channel A - accepts up to 220 days
What actually happens:
Booking.com receives updates for 400 days (limited by your property setting, not Booking.com's 572-day limit)
Channel A receives updates for 220 days (limited by Channel A's 220-day limit, not your 400-day setting)
To send Booking.com updates for the full 572 days: You'd need to increase your property update period to 573 days or higher in Property Settings.
Why isn't my availability showing for future dates on channels?
If your availability is not showing on booking channels for dates far ahead, your Channel Manager update period may be set too short to cover those dates.
To extend how far ahead your updates are sent:
Go to My Apps > Channel Manager.
Click your property name in the top right corner and select Property Settings.
In the General tab, find the Update period field and select a longer range from the drop-down menu.
💡 Rates and availability sent beyond a channel's maximum update period will not sync to that channel.
💡 Most channels have a maximum update period of 1-2 years. Rates and availability sent beyond a channel's maximum update period will not sync to that channel.
