Instead of actual years, it may be less work to mark the time as “One Year Ago”, “Two Years Ago”, etc. That way you won’t have to update the page as the years go on and you can just focus on the events themselves.
This is a very nice idea.
I know this hasn’t been updated in a while, but I wanted to let you know that the current volume of Amazing Spider-Man stablished that Peter became Spidey 13 years ago (therefore, in 2001)
Marvel Plot Points 
Given that one of the event books will be Annihilation, could you work in some Cosmic events into this timeline?
