Some of us often operate with dates. If it's problem for you to calculate how many days are between two specific dates or how many workdays left to your holidays then PS Date Calculator is for you. This program can tell you the difference between the specific dates or date plus/minus inserted number of days in years, months, days or even in minutes and show you some stats. It's very useful and simple. After choosing the dates and pressing the "calculate" button in the first tab you can see the calculated difference. In the second tab there is the list of the holidays. In the third tab you can use two calendars. Also you can see the details of the certain day in the fourth tab. Date Calculator can save output data to disk for further using. There are some options in the main window to specific calculation, e.g. take into account sub days (holidays or illness) or 6-day week (workdays). So it's not a bad tool (and free therewith) to work with time, but non-German users can't use their local holidays in calculation, there are only German holidays in this calculator. I hope developer will continue improving this tool and will include other holidays and features.
