WPS office software could be compatible with Microsoft Office, and these training contents help students or home workers finish their work efficiently.

Today, we are going to introduce basic usages of three commonly used date functions. They are namely the TODAY function, NOW function, and DATEDIF function. We can use the date function to insert the current date and time quickly. Also, we can use this function to update it in real-time. We can also make a countdown calendar with it.

· 1.TODAY function

To quickly insert the current date in the table, click cell B5, enter =TODAY (). Then press Enter to enter the current date.

Every time the table is reopened, the current date will be refreshed. If it is not refreshed, press F9 to refresh manually.

· 2.NOW function

To enter the current time and date, enter =NOW(). Then press Enter. Each time the table is reopened, the current time will be refreshed, or we can press F9 to refresh manually.

· 3. DATEDIF function

If we want to make a countdown calendar, we can use the DATEDIF function.For example, now we want to calculate how many days are left until the final exam. Click cell D21 and enter =DATEDIF (TODAY(),C22,D).

There are three parameters in this formula, namely:

Start date, End date and Comparision Unit.

Since we need to calculate how many days are left until the final exam, the Start Date should be the current date. Therefore, we need to enter the TODAY() function.End date is the date of the final exam. So here, we select C22.Comparision Unit is Day, and “D” represents the day.
