To summarize North America, Cuba now begins and ends DST on the same dates as the United States, Canada, the Thule area of Greenland, Saint-Pierre and Miquelon, the Bahamas, Bermuda, the Turks and Caicos Islands and the Mexican cities of Tijuana, Mexicali, Ciudad Juarez, Ojinaga, Ciudad Acuña, Piedras Negras, Anáhuac, Nuevo Laredo, Reynosa & Matamoros (the 2nd Sun. of March until the 1st Sun. of Nov.). However, although Cuba time is the same as New York time, Cuba begins DST two hours before New York and ends DST one hour before New York. In other words, Cuba begins DST at the same time as the Saint-Pierre and Miquelon Islands and ends DST at the same time as New Brunswick and Nova Scotia. Unfortunately, unlike Europe, all of which does the time change at the same time (with the exception of Azerbaijan, which changes one hour earlier), the change happens in each North American time zone at 2 AM local time. The only places in North America that do DST on a different schedule now are most of Greenland, which changes at the same times as Europe, and the balance of México (except Sonora, which doesn't do DST), which still follows the same schedule the U.S., Canada and the others followed until 2006, the 1st Sun. of April until the last Sun. of Oct.

The database already assumes this, so no change is necessary, but Cuba has had different rules the past two years, so it was not obvious that this would be the start date this year. http://www.granma.cubaweb.cu/2013/03/04/nacional/artic10.html Best regards, Steffen Thorsen - timeanddate.com
