From TriSun Software:
Date Time Counter is used to count years, months, weeks, days, hours, minutes and seconds for the past/future important events based on current date and time, such as these important events: birth, marriage and anniversary. For the future events, it is just like a countdown timer, for the past events, it is a time tracker. The numbers of date time elements are refreshed automatically on the main interface, and you can set the refreshing frequency. Also, copying the value of any field, saving/loading events, thousands separator and decimal in all numeric fields features are provided. Of course, some useful options are built-in: refreshing frequency, precision of the numbers of years, months, weeks, days, hours, minutes and seconds, font name and size of the events listing, foreground colors of different event types. An event is a basic data unit of this program, and a set of events can be saved as a data file (.xml format). Date Time Counter allows you to load the specific events set from a data file, usually, you can make your events data file according to individual, used scope, such as son' events, father's events, work events or life events. If you are very strict, or you like to track the countdown for some important events, it may be useful.
