The hottest itâs ever been in Key West is 97Â° F (36Â° C), and that was way back in 1880. At the peak of summer, the average high is 89Â° F (32Â° C).
To count the days before a date, you can use the TODAY function. Example. The example may be easier to understand if you copy it to a blank worksheet. Create a blank workbook or worksheet. Select the example in the Help topic. Note: Do not select the row or column headers.
The Excel DATEVALUE function converts a date represented as text into a proper Excel date. For example, the formula =DATEVALUE(12/31/2015) returns a serial number in the Excel date system that represents December 31, 2015. Proper Excel dates are more useful than text dates since they can be directly manipulated with formulas and pivot tables to create summaries and perform other date-based analysis.
