Search for Countup Clock in Topics

I was looking to make a countup clock that would be able to count off time in seconds, minutes, hours, days, and years using seven segment displays. I have yet to be able to find an instructable like this. I imagine it would be very similar to a normal clock; however I do not know enough about electronics to be able to modify the standard clock instructables to be able to make my own.  The only way I know to do this with the knowledge I currently have is to make a mini PC and that would be cost prohibitive as well as overpowered.   The idea came up because I have my one year anniversary approaching and I figured it would be neat to have a clock whose sole purpose is to give an exact time count of being married.  I played around with the idea of having the clock play a song or display something any time a new year was added, but I figured for now to just stick to the basics.   If anyone knows of an instructable that fits this idea or is willing to make one/point me in the right direction here, that would be fantastic.
