Change the time zone

When you change the current time zone, all Calendar views (view: Views give you different ways to look at the same information in a folder by putting it in different arrangements and formats. There are standard views for each folder. You can also create custom views.) are updated to display the new time zone, and all Calendar items move to the new time zone. For example, if you move from the Pacific Time zone to the Mountain Time zone in the United States, all of your appointments are displayed one hour later.

  1. On the Tools menu, click Options.
  2. Click Calendar Options.
  3. Click Time Zone.
  4. Under Current time zone, type a description in the Label box.
  5. In the Time zone list, click the time zone you want.
  6. If you want your computer clock to automatically adjust for daylight saving time changes, select the Adjust for daylight saving time check box.

This option is available only in time zones that use daylight saving time (DST).


To quickly change the time zone on your computer, you must be viewing the Calendar by days; right-click the empty space at the top of the time bar, and then click Change Time Zone on the shortcut menu.


  • All-day events also move to adjust for the change in time zone. One-day events appear to be longer than 24 hours. For example, the July 4th U.S. holiday spans from 12:00 A.M. July 4th until 1:00 A.M. July 5th when the time zone changes from Pacific to Mountain.
  • When you adjust time zones and the daylight saving time setting in Microsoft Outlook you are also adjusting the same settings in Microsoft Windows.
  • Some time zones do not have DST. When Outlook is set to a non-DST time zone, such as Arizona in the United States, the Adjust for daylight saving time check box is cleared and disabled.
  • When Outlook is set to a time zone that has DST, the Adjust for daylight saving time check box is selected. You can clear the check box, although this is not recommended.
