In Excel, using system time and birth date to calculate age, something age and the actual age, in the personnel management, payroll statistics frequently encountered, the following is to introduce the method of calculating the age problem (in Excel2003, for example, the other version is similar).
Steps:
Years of age calculation (method i):
Enter the formula =year (today ())-year (B2) in cell C2 (as shown in the following illustration). Then enter t
= mktime (Date ("G", $time), date ("I", $time),
Date ("S", $time), date ("n", $time),-1, date ("Y", $time));
Return Date (date ("Y-m", $last _month_time). "-D h:i:s", $time);
}
echo Last_month_today ($time);
But then there is another problem, there is no 2011-02-31 such a date, how to do? Now the requirement is for such a date to display the last day of the month. The following code:
Copy Code code as follows:
$time = Strtotime ("2011-03-31");

The following is the use of JS code to achieve the Baidu map to calculate the distance between the two, the code is as follows:
to tell you how C # according to Baidu map, calculate the driving distance between the two places
Recently used in accordance with the latitude and longitude calculation of the Earth's surface two distance between the formula, and then use JS to achieve a bit.
There are probably two ways to calculate the distance between two points on the Earth's surface.
The first is the default Earth is a smooth spherical surface, and then calculate the distance between any two points, this distance is called the Grea
