After installing Outlook I have found the default installation does not automatically add holidays to the calendar. When scheduling appointments and tasks it is important to know the holidays. For example, a husband can find himself in a lot of trouble if he schedules a dinner with a client on Valentine’s Day. I have also found instances where users entered the holidays by hand into their calendars. In either case holidays can be added to Outlook with just a few clicks of the mouse. Here are the steps you need to take to enable holidays in your Outlook calendar.
Step 1: Tools->Options
In the top menu of Outlook select Tools then Options in the menu.
Step 2: Select Calendar Options
Step 3: Select Add Holidays
In the middle of the next screen select “Add Holidays”.
Step 4: Select Country
Step 5: Option Screen
You may or may not get the following screen.
If this screen appears just press “Yes”.
Step 6: Wait for Holidays to Be Added
Step 7: Done
Press OK to close the other screens that are open.
Step 8: Check Calendar
After this you should be able to visit a date that is known to be a holiday like Valentine’s Day for example. The holiday will be displayed at the top of the calendar in Outlook as shown below.
