Observation date
Observation date: The date we read a value from its public source.
How we measure it
Every row carries it. A dataset's freshness is the age of its newest observation date.
What it is not
It is not the date a page was built or the date a sale happened; sale rows carry their own sale date.
Where it appears in the data
Field names as the API returns them; each dataset's page in the API lists the field's type and unit.
