I'd say if you find counting days helpful to your recovery, count them. If it is bothering you, don't count them.
Personally I found that when I counted it was counter productive. I would often relapse right before an aniversary ie: 30 days, 60 days, 90 days, never made it past that until this time!! I have a general idea how much clean time I have, about 8 months or so, but I couldn't tell you my sobriety date, it was sometime in May. It's working for me. Find what works for you and stick with it. Take care.
