The diary can be displayed in monthly, weekly or daily views, whatever view is initially selected it will always open at the current month, week or day as appropriate.
From any view a single click will open a page for bookings to be added or existing bookings to be amended. It is also easy to page back and forth between previous/next month/week/day as appropriate.
The monthly view provides a good overall view of bookings or availability, for aircraft with a lot of bookings each day the weekly or daily view is perhaps a better choice.
Your favourite view can be setup so that it is automatically displayed as soon as you have signed in.
