This is actually something google likes because they think you should always update the information on a page whether it is changing some information or adding to it. If you have an article listing some events and now it is going to be the next year then if the event is an annual thing you will have to change the date. This is the king of thing google likes, it is fresh information even though it may be just a sentence it is new. Also if you come up with new information it is just fine to ad to the article.
