You will have one more hour to talk to your loved ones in France. On Sunday, October 27, France went to winter time. At 3 o'clock in the morning it will be 2 o'clock.
History that you do not take your feet in the carpet in case of business call with France on Monday, remember that the United States does not change time at the same time. It is a 2005 American law, which came into effect in 2007, which is responsible for this discrepancy. Here, the transition to winter time is on Sunday, November 3rd.
For a week, there will be five hours of time difference with France if you are on the East Coast, eight if you are on the West Coast.
