If both date arguments are numbers, DAYS uses EndDate–StartDate to calculate the number of days in between both dates. A date that represents the first, or starting date of a given period. Dates may be entered as text strings within quotation marks (for example, "2001/1/30"), as serial numbers (for example, 36921, which represents January 30, 2001, if you're using the 1900 date system), or as the results of other formulas or functions (for example, DATEVALUE("2001/1/30")). Note: Excel stores dates as sequential serial numbers so that they can be used in calculations. By default, Jan 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39447 days after January 1, 1900. Remarks

The difference between the months in start_date and end_date. The days and years of the dates are ignored Finds the number of days between the end date (15-MAR-2021) and start date (1-FEB-2021). When you enter a date directly in the function, you need to enclose it in quotation marks. Result is 42. Dates are stored as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,447 days after January 1, 1900.As there are 30 30 30 days in April, we count the days from the 2 2 n d 22 To calculate how much time until a date, you must perform a subtraction between the final, desired date and the time of "now". The operation is straightforward, but you need to be careful about some possible catches. This formula subtracts the first day of the ending month (5/1/2016) from the original end date in cell E17 (5/6/2016). Here's how it does this: First the DATE function creates the date, 5/1/2016. It creates it using the year in cell E17, and the month in cell E17. Then the 1 represents the first day of that month. The result for the DATE function is 5/1/2016. Then, we subtract that from the original end date in cell E17, which is 5/6/2016. 5/6/2016 minus 5/1/2016 is 5 days. Need more help?

The "MD" argument may result in a negative number, a zero, or an inaccurate result. If you are trying to calculate the remaining days after the last completed month, here is a workaround: Important: We don't recommend using the "MD" argument, as there are known limitations with it. See the known issues section below. Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data. For every "incomplete" year, you must sum the duration of each "complete" month between the dates. There is no way to escape this non-mathematical operation that comes straight from the quirkiness of our calendar: thirty days hath September....
