The booking sheet display the reservation using grid starting from Jan to Dec which you can scroll using the scroll bar. When user is getting close to the end of the year this means that the user has you go from one year to the next and back.
To avoid having to go back and forth there is an option to select the start month for the grid. From the main menu select “Year” then “Start month” you will note that a small dialog box will appear, here you can select the start month of the grid son instead of a grid from Jan to Dec you could set the grid from Jul to Jun for instance. This should greatly help when making bookings toward the end of the year.
