how can change magento calendar?

How can I change the date that appears on the messages from Hegira to Gregorian calendar?

• When I received and sent messages, the date that appears is the date on the Hegira calendar and not the Gregorian calendar which is I'm more familiar with. Hegira Calendar is the other calendar being used in Saudi Arabia and other Arab countries. I would like to know how can I change it.

• Answer:

  Check to see if you have the correct "Time Zone" entered, if not, change it. The correct time zone should have the correct Calendar. 1. Click on the "Calendar" tab at top of your yahoo mail page. 2. Click on the "Options" link in Calendar. 3. Click on "General Preferences" in calendar options. 4. Select your time zone from the page that opens. 5. At the bottom of the page, click the blue down arrow and select your country. Then save. Note: Yahoo is on Pacific Time for all mail in the US. It's GMT -8:00 US/Canada Pacific. If that doesn't get it corrected, go into your Account Info. 1. Click "My Account" at the top of this page to open your Yahoo ID card. 2. Go down to "Address/Contact Information and enter U.S. Central across from Time Zone. 3. Ensure your location in the US is correct in this section also. 3. Go to the bottom of the page and click "Finished."
