In reality, we often face a similar situation, perhaps a friend married, perhaps a long holiday to travel. Anyway, the situation is similar, is to know a specific date, you need to calculate the actual number of days from now. In general, the simplest and stupidest way is to take a calendar and count it day by day. Of course if you are using Windows 7, congratulations, no more days to get cramps, because we already have a simpler way-"calculator."
The "calculator" in Win7 has a lot more function, and it adds a lot of special operations. Take the article at the beginning of the example of the Wei, you can through the "View" menu → "date calculation" first switch to the date calculation mode, and then fill in the "To" column, and directly calculated from the actual difference between the days so far. In order to facilitate the user to read, Win7 also very carefully for us to provide the number of days and conversion to the future of the two sets of calculation results, the need for which direct call can be.
In addition to calculating the actual number of days from now in the future, the WIN7 calculator can also use this formula in turn. For example, you can calculate the end date of an increase/decrease of XX days with a date by adding or subtracting the number of days on a specified date, and you can also choose between the month and day or the number of days.
If you have some daily investment, Win7 calculator can also help, such as calculate an ounce of how many grams is equal (fried gold necessary)? How many years are we going to finish our mortgage? How many years to rent a house to recover costs and so on.
In addition, you can use the Win7 calculator to calculate your daily fuel consumption. This is nothing to say, enter the actual number of kilometers and the final cost of the oil value. OK, the technical level at a glance.
Postscript
As you can see, the Win7 Calculator incorporates more content than the previous "calculator" in mind, which makes it no longer just a tool to count, but really becomes a good helper in our daily lives. There are, of course, a lot of similar scenarios, limited to space and we can't enumerate them.
