I presume to qualify for Jobseeker's, even at 65, you have to be seeking a job?
why do they allow you to draw JB if you effectively leave your job and have a pension.
If you wait until you are 65 you can claim Jobseekers Benefit for the full year until you reach 66.
There is a concession for persons aged 65 signing on - the 9 month rule isn't applied.
The concession won't apply if you sign on at age 64.
I had a look at the operational guidelines and it's not 100% clear, but you may be right. The guidelines appear to say that if there is an entitlement to JB on the 65th birthday, it will be extended to 66.

If a person signed on at age 64 they might exhaust their entitlement before age 65.
If you are getting Jobseeker's Benefit (JB) and are aged between 65 and 66 when your JB would normally end, you may continue to receive it until the age of 66, provided you meet the PRSI requirements.
