New York and Morocco Time Difference

Morocco is generally 5 hours ahead of New York when New York is observing Eastern Daylight Time and Morocco is on UTC+1.

For example:

12:00 PM in New York = 5:00 PM in Morocco

Morocco has a distinctive clock schedule because it temporarily moves back one hour during Ramadan. In 2026, Morocco's clock is scheduled to move from UTC+1 to UTC on September 20, although future dates can be subject to change.

This means the time difference should be checked for the exact travel date, particularly around Ramadan and the United States' daylight-saving changes.
