If you know how many years or months you got left until the retirement or any other event or project in your life, Excel can return you the exact date and the number of days left to reach it.
If you are using the same entries all over again, you can create a custom list with these entries and when you need it just enter the first one then drag the cell down for the rest to fill out automatically.
When you want to copy the result of the cell to another cell in Excel, the target displays an invalid references error messag. This error can be avoided by copying cell value into target cell and not the whole formulas.
