Sure you can, just not by months, you would need to use weeks instead to retain integer values. A half year would be 26 weeks and a quarter year would just be 13 weeks. Of course this fails if you wish to divide further, but at that point you could just say 2 months and people would know for certain you are saying 8 weeks.
Just so you and everyone else is aware. In the link you posted, everything after the question mark is a tracking id, using the link without that part of the link works perfectly fine and reduces traceability.
