Day - an integer corresponding to the day of the month, from 1 to As well as month, the day argument can be supplied as a positive and negative number, and Excel calculates its value based on the same principles as described above. At first sight, supplying negative values in the month or day argument of the Excel DATE function may seem absurd, but in practice it may turn out quite useful, for example in the complex formula that converts a week number to a date.
Instead of specifying the values representing the year, month and day directly in a date formula, you can get some or all arguments as results of other Excel date functions: Excel DATE formula to return a date based on values in other cells The DATE function is very helpful for calculating dates where the year, month, and day values are stored in other cells.
In this case, you can use DATE in liaison with other functions to convert a date stored as a text string into a serial number representing the date: Adding and subtracting dates in Excel As already mentioned, Microsoft Excel stores dates as serial numbers and operates on those numbers in formulas and calculations.
Adding days to a date: Subtracting days from a date: To subtract a date from today's date: For more information, please see: How to convert week number to date - the example demonstrates how you can get a date in Excel based on the week number, and also how to get a month corresponding to the week number.

Using Excel DATE formulas in conditional formatting In case you want not only to calculate but also highlight dates in your Excel worksheets, then create conditional formatting rules based on DATE formulas.
Supposing you have a list of dates in column A and you want to shade dates that occurred earlier than 1-May in orange and those that occur after May in green. The DATE formulas you want are as follows: You can find the links to in-depth tutorials at the end of this article.Couples With A Wider Age Gap
