Hashirama finally died 34 years before Naruto was born according to the information we have from Seelentau's timeline which all have references https://naruto.fandom.com/wiki/User:Seelentau/Naruto_Timeline#1st_January_to_31st_December_34_bNb and it makes sense because he knew Tsunade who was old enough to be taught how to gamble. So they would more likely be born after the Sannin 33 years before Naruto's birth so about Fugaku's age.
