QuickCalend is a very simple but very useful application in which many different holidays are collected. Of course this is a normal calendar, however, for each day you can see what holidays are on this day, they are all detailed and updated daily with new information. In general, the application is quite simple and does not take place, and it will be able to replace the standard calendar, well, or become a good addition to it.
