What time zone is Costa Rica in?
Costa Rica is on Central Standard Time (-6 GMT) and Daylight Savings Time is not observed. This means the time difference between Costa Rica and U.S. cities varies throughout the year. For example: during the Summer time in the U.S., Costa Rica is 2 hours behind the East Coast. After the East Coast observes Daylight Savings Time and "falls back" an hour, Costa Rica is only 1 hour behind the East Coast.
