What to know
The EXEC next manual warns not to use the child restraint if it is more than 10 years old, and points you to the label or the stamped do-not-use-after date on the bottom of the seat. That one 10-year window covers all three modes, from rear facing at 5 to 50 pounds through forward facing to booster at 40 to 110 pounds, so the clock does not reset when you convert the seat. It is certified for use in aircraft in harness mode only; the manual states the restraint is not certified for aircraft use when used as a booster. Do not read the older EXEC's dates across to this seat, they are separate products with separate labels.
The date of manufacture is on the seat itself. The model number, date of manufacture, and stamped do-not-use-after date are on a label on the bottom of the child restraint (and on the underside of the base for seats sold with one). Nuna also prints this information on the registration card packed with the seat.
Safety note: SeatCheck summarizes manufacturer and NHTSA guidance, but the label on your own seat and its manual are the final word. When in doubt, contact the manufacturer with your model and serial number.
