How it’s counted

  • Being 18 means the 18th birthday has already happened.
  • Only know the year? Subtract it: 2026 − 2008 = 18 → they turn 18 on this year’s birthday. More than 18 → already 18.
  • Birthday unknown? Thai law counts age from January 1 of the birth year (Civil and Commercial Code, s.16).
