The GNOME Calendar can be used in the state which it is shipped but there
are tools available to make sure it is setup the way you would like it to
be. The first place you should go is the GNOME Calendar Preferences. You
can find the Preferences dialog by selecting the
menu item from the menu.
The Calendar Preferences dialog is broken up into three tabs, Time display,
Colors, and Todo List
Time - This tab is broken up into three main sections: Time format, Weeks
start on, and Day range.
Time format - This allows you to choose between a 12 or 24 hour format
clock.
Weeks start on - This allows you to define what day your week will start
on, Sunday or Monday. This will affect how the calendar is laid out in the
Day and Week views.
Day range - This section lets you choose what time your days will start
and end. Any hours outside the range selected will be shaded on your Day
view.
Colors - This tab allows you to change the default colors used in the
Calendar. There are seven color choices you can customize: Outline,
Headings, Empty days, Appointments, Highlighted day, Day numbers, and
Current day's number. Each choice has a small color selector box next to
it. When you press this box you will be given a color selector dialog in
which you can choose the color you want. Once you have selected a color the
small sample calendar on the right side of the tab will preview your choice.
Todo List - This tab allows you to define which columns will be shown in the
Todo List in the Day View. You can set the Summary, Due Date, and Priority
columns.
Once you have made the changes to the Calendar Preferences you can press the
Apply button to apply them.
