Wrong month of birth on Online Check in

Guys, I'm trying to call Ryanair but unfortunately my landline phone doesn't allow me to call their Italian number or the Rest of the World one.
Here's my problem: I'm not sure to have entered my D.o.B. right (one month erlier) even if I checked it 1000 times before press "Check-in" on the Online Check In, all the other fields should be ok. Is there a possibility that they refuse to let me board the plane? Do they check those kind of things carefully or not? I'm a bit scared as there is no way to check it myself from my computer and no way to call them from my phone.

Thanks!

The date of birth does not appear on the boarding pass.
The boarding gate agent will look at your passport or identity card just to check that the name is the same as the name on the boarding pass.
It is highly unlikely that he will check further - I have never seen it happen ...

as dr house said: Everybody lies.. especially this guy which put comment above.

ALL details must be correct on your boarding pass, You can't see it but it's in BARCODE

so if you have plans how to plan 6o gbp then better call ROW - ASAP- line and correct before your flt .. or forget about it and prepare cash at apt

No need to be insulting. Please watch your language, FR starter.
I am not a liar. I just gave my opinion, and I confirm it's highly unlikely that the gate agent will check the date of birth.
