If you use the Calendar feature in Outlook to keep track of your important meetings and events, as well as birthdays and anniversaries for friends and family, you may also want to add holidays. Outlook allows you to add holidays for one or more countries.

Outlook for Windows

To add holidays to your Outlook calendar on Windows, do the following:

• Open Outlook.
• Click the Calendar link.
• Click File ?  Options ?  Calendar.
• Under Calendar options, click Add Holidays.
• Check the box for each country whose holidays you want to add to your calendar.
  • You may also want to put a check mark next to Christian Religious Holidays, Islamic Religious Holidays, and/or Jewish Religious Holidays if you desire.
  • Christmas and Easter are considered secular holidays (as well as religious), so they are added to your calendar when you choose United States without needing to also select Christian Religious Holidays.
• Click OK.
• When the Holidays are finished being added to your calendar, click OK to close the Outlook Options window.
