Which date should I go with to qualify for naturalisation

[Scanner]

I am a bit confused. When am I actually due to apply for naturalization after I receive my ILR? I know it is minimum of 1 year after I get my ILR but below is the reason why i am confused

I applied on the 02/05/2012. On my biometric card it says place and date of issue was 23/10/2012. However the card says valid until 02/05/2022 (exactly 10 years from the day I sent in my application NOT 10 years from the issue date).

So my question is does the one year start counting from 02/05/2012 or from 23/10/2012?

i may be entitled to apply by May 2013 but not know it?

thanks for your advice

Your ILR starts from the date when it was approved and issued, which in your case is October and not the date when you applied.
