How to use this feature
The fixed start and end date for your booking profile are set at the top of the 'advanced' tab.
You can either enter the dates by hand or click on the little calendar icon to open a date picker. The format can either be the simple standard "yyyy-mm-dd" backwards format (e.g. 2013-12-25) or you can enter a date according to your language and country rules.
As soon as you set one or both of these, the system will stop allowing people to book beyond these limits.
To turn them off, just delete the dates in the boxes. We will then go back to showing your availability on a "rolling" basis.
