Qatar 1 Riyal date

Can someone tell me where the date is located on a Qatar 1 Riyal p-28? It is either aq 2008 or a 2015. The numbers I see seem to be the banknote serial number. Where on the banknote shows the year? Thank you. I struggle with the non-english banknotes.

The note is an "ND" No Date note, so 2008/2015 does not appear anywhere. We would have to know what the serial number run is for each year to determine with that method--not sure anyone knows that information outside the monetary authority of Qatar.

(I think) You can tell from the signature at right. The one currently on our Numista page is the 2008 version. A different signature at right is the 2015, you can see it at colnect:

Hello, Qatar P28 doesn't has the date marked on it. Maybe the difference on date is because the signatures. See on the link:

Hope that was helpful.

Thank you for the responses. I appreciate it. I would then assume I have the 2015 version since my signatures are different from the ones on Numista.
