Off the top of my head, and without having RDA in front of me, a period of activity is supposed to be the period when a person was active in their primary field of endeavour. So  a person could be known for a particular profession, and retire from it and but live for decades more.

Subject: [PCCLIST] "Active" date same as death date

When I assign “active” dates for a person, I’m used to not knowing their birth and death dates. But today I ran into a source that told me someone became active in 1649 and died in 1675. Of course that also has to be the end of his “activity.”

So do I set the 046 up as ǂs 1649 ǂt 1675 or as:
ǂg 1675 ǂs 1649 ǂt 1675

since I know his death date but not his birth date?
