Let me explain!
If we start in February, the month Tom was born, this is the recorded order of dates...

1877-02-09
1877-02-11
1877-02-12
1877-02-12

^^ February after March, no April?
Handwritten notes, memory (a lot of babies, boys, girls, look the same), re-asking others, etc., and filling in the official record post-event
A lot of errors could have been introduced in this process
The second point is that Tom Crean's record was not the only record in February or indeed on that page that was different from the reported birth date
There were 6 instances: maybe all those parents made mistakes
Mary Spillane=baptised 11 days earlier than birthdate
Eugene Keane=-8 days
Tom Crean=-9 days as "Joanna"
Mary Moriarty=-8 days
Anne Moynahan=-6 days
John Kennedy=-7 days
Baptismal Ellena Sullivan (12th February 1877) is the birth of Kate Sullivan (also 12th February 1877) [Helen ≠ Catherine]
Born in Annascaul, she is three lines above Tom in the baptismal record
Mary Moriarty's parents (she was one of those six people in February/March that was baptised earlier than born) are Eugene/Joanna Callaghan in baptismal and Eugene/Johanna Griffin in birth records
[There's also one small error of Garvan and Garvey but I'll ignore that...]
