From NHTSA
From NHTSA: "Your child under age 1 should always ride in a rear-facing car seat." Stay rear-facing "until he or she reaches the top height or weight limit allowed by your car seat's manufacturer." (NHTSA) Find a certified Child Passenger Safety Technician through NHTSA. Check the label and the maker's instructions, and ask your pediatrician about your child.

Between 6 and 9 years from the manufacture date, for the 22 that publish one. The longest is the Clek Liing at 9 years. The date of manufacture is on the seat's label; try the expiration calculator.
