This component consists of a paragraph and then a script that calculates the years from a given date up to now.
You have to create an empty paragraph on the page with the class name of '.anniv'. Put it where you want the result to appear. The script will populate that paragraph. In the script you find commented how to set the time and date you want to count up from. Remember that in java scripts January is number 0 and December will be number 11.
Towards the end is a place where you can write some text you want to appear. Use this script for something you want to remember, so that you don't miss the anniversary.
