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.
Calculating the number of days using Excel is pretty simple. Just use a formula to subtract the later date from the earlier date. For example, if cell A1 contains 1-Jan-2004 and cell A2 contains 03-Mar-2004, you simply enter the formula =A2-A1 in cell A3 to get the number of days.At first the result may look strange.owever, calculating the number of months or years between two dates isn't so obvious. There's a Function in Excel that makes this task easy but for some reason Microsoft has hidden it away. You won't find it in the Paste Functions list (Insert, Functions).
