The DATE function can build a date from three different values, using the year, the month and the year. So if you wanted to get the 19th of June 1972, you could do it like this:
=DATE(1972,6,19)
You can use cell references in it to create dates very quickly, like getting the same date for different years. So you could quickly put a list of years in a column, say column A, starting in cell A2. Then in B2, in order to list the 1st of January for each of those years, you could type in:
=DATE(A2,1,1)
Then you could copy that down column B for each value in column A. You would now have a list of dates. It is a very useful function when you need to quickly create dates.
Use data validation and set the condition to allow only the date range you specify.
You can use the NOW(), DATE() or TODAY() functions. You can type Ctrl and the ; to get today's date. You can just type dates in.
use conditional formatting
You can use the TODAY function or press and hold the Ctrl key and the ; key.
numerical
a serial value to the date
=IF(G17="","No Audit on File",(IF(G17>TODAY(),"Valid","Expired"))) Works!!
Use conditional formatting to set the condition when you enter a particular date.
Format / Cells / Date
You use the YEAR function. So if the date was in cell A5, to just get the year from it, in another cell you would have to put the following formula: =YEAR(A5)
