How these ages are calculated
Subtract the actor’s birth year from the air-date year, then subtract one if their birthday had not yet occurred. Tables and the episode explorer use completed years. Missing, invalid, conflicting or unchecked birthdays do not produce an exact age. Historical broadcast ages do not imply that an actor is still living.
Premiere dates and matched birthdays were cross-checked against TVmaze’s Game of Thrones guide on 2026-10-16. Actor-name links identify birthday sources; premiere-date links identify episode sources. TVmaze data is used under CC BY-SA. A database match is not independent biographical authentication; unresolved disagreements are withheld. Episode rosters and guest credits remain under review.
