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.
If you want to calculate the number of days between two dates you can simply subtract the older date from the newer date. The result will be an integer that represent the days between dates. In the example, the formula in cell D6 returns 365, since there are 365 days between 1/1/1999 and 1/1/2000. Dates in Excel are simply serial numbers that start on 1/1/1900. In the example, the formula in cell D6 simply subtracts the numeric value of 1/1/1999 (36161) from the numeric value of 1/1/2000 (36526) to get a result of 365.
