The time difference between the U.S. time zones and Turkey will increase by one hour as Daylight Saving Time (DST) ends on Sunday.
DST will end in the U.S. at 2 a.m. local time, when Americans will turn their clocks backward one hour. This measure will add an extra hour to the current time difference between Turkey and the U.S.
When Americans turn back their clocks Sunday morning, the time difference between Turkey and the Eastern time zone in the U.S., which includes cities such as New York, Washington DC, Atlanta and Miami, will increase to eight hours from seven.
The time difference between Turkey and central U.S. cities like Chicago, Houston, San Antonio, Dallas, New Orleans, Memphis, Kansas City and Minneapolis will rise to nine hours from eight.
For cities such as Albuquerque, New Mexico; Denver and Salt Lake City located in the Mountain Standard Time Zone, the time difference will be ten hours instead of nine.
For cities in the Pacific time zone -- Las Vegas, Los Angeles, San Francisco and Seattle – the ten hour difference will increase to 11 hours.
And the difference between Alaska and Turkey will increase to a total of 12 hours from 11, while Hawaii goes from 13 to 14 hours.
The new time differences will be in effect until March 11 next year, when the U.S. will again start observing DST.
