This resolves the previous issue completely.
Below is the original post for historical reasons.
In a previous post, we had discussed
when a Cardinal loses the right to vote in a Conclave. In brief, it depends on when a Cardinal reaches the age of 80.
We have an unusual situation with
John Cardinal Njue, Archbishop Emeritus of
Nairobi, Kenya, and Cardinal-Priest of
Preziosissimo Sangue di Nostro Signore Gesù Cristo.
In his case, we only know the year in which he was born (1944) - but not the month nor day.
So when does he reach the age of 80?
In my opinion, in fairness to Cardinal Njue, one must treat him as if he was born on the last day of the year 1944 - thus losing his vote on 1 Jan 2025 (see the above linked post for details).
I note that on the Vatican website, there is a
List of Cardinals in order of Age and on that list his birth date is listed as "31-12-1944" but the bios to which it links only gives the year of birth. This would seem to suggest they agree with my view.
God willing, the need for a Conclave in 2024 will not occur and complete clarification of the issue will not be neccessary.
