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.
2. To add a number of years, months and/or days, use the DATE function. Note: the DATE function accepts three arguments: year, month and day. Excel knows that 6 + 2 = 8 = August has 31 days and rolls over to the next month (23 August + 9 days = 1 September).o enter a date in Excel, use the / or - characters. To enter a time, use the : (colon). You can also enter a date and a time in one cell. Note: Dates are in US Format. Months first, Days second.
