How old was albus dumbeldore when he died?

Albus Dumbledore never turn 150. On his last birthday before he died he turned 116, because he died 1997 and was born 1881. He was born in July or August.

I think 35 in (dog years),,,,, 5 in (human years)

150 yrs old from the hp-lexicon: Birthdate: 1881 (JKR), probably in July or August. This date supercedes Jo's statement in 2001 that Dumbledore was "about 150 years old" (Blue Nose Day) and fits...

he was 78 when he died , hope this helps !:)

He died at age 73 of a heart attack.
