Add, minus, divide and multiply time values in hours, minutes and seconds. Convert to and from fractional time units. Use the DAE (date analysis engine) to find the day of any date in the Gregorian calendar (the one used worldwide) within a range of up to 15 centuries since the inception of that calendar (about 1583 AD). Military time conversion supported. Use the program for work, research or just plain fun!
