When it comes to calculating dates in Excel, DATE is the most essential function to understand. As you probably know, Excel does not keep the year, month and day for a date, nor does it explicitly store weekday information in a cell. Instead, Microsoft Excel stores dates as serial numbers and this is the main source of confusion.
Not all Excel date functions can recognize dates entered as text values, therefore it's not recommended to supply dates directly in calculations. Instead, you should use the DATE function to get a serial number representing the date, the number that Excel understands and can operate on.
Excel interprets the year argument according to the date system set up on your computer. By default, Microsoft Excel for Windows uses the 1900 system where January 1, 1900 is represented by the serial number 1. For more details, please see Excel date format.
Tip. To avoid confusion, always supply four-digit years. For example, if you input "01" or "1" in the year argument, your DATE formula will return the year of 1901.MonthIf the month argument is greater than 12, Excel adds that number to the first month in the specified year. For example, DATE(2015, 15, 5) returns the serial number representing March 1, 2016 (January 5, 2015 plus 15 months).If the month argument is less than 1 (zero or negative value), Excel subtracts the magnitude of that number of months, plus 1, from the first month in the specified year. For example, DATE(2015, -5, 1) returns the serial number representing July 1, 2014 (January 1, 2015 minus 6 months).DayAs 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.
Tip. 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.Excel DATE formula examplesBelow you will find a few examples of using DATE formulas in Excel beginning with the simplest ones.
Instead of specifying the values representing the year, month and day directly in a formula, you can have some or all arguments driven by of other Excel date functions. For instance, combine the YEAR and TODAY to get a serial number for the first day of the current year.
Another scenario when the Excel DATE function proves useful is when the dates are stored in the format that Microsoft Excel does not recognize, for instance DDMMYYYY. In this case, you can use DATE in liaison with other functions to convert a date stored as a numeric string or number into a date:
As already mentioned, Microsoft Excel stores dates as serial numbers and operates on those numbers in formulas and calculations. That is why when you want to add or subtract some days to/from a given date, you need to convert that date to a serial number first by using the Excel DATE function. For example:
Great info that you have here. Please help. I am working on my sheet of manage data,I want excel to series easily for mekindly help mehow can i put the series in this wayfor example01/201702/201703/2017main thing is that 01, 02, and 03 is not date or monththis is my work sheet serial number i have alot of work sheet thats way i m manage one sheet for inform me to whos my work done or not so kindly help me how can put serial01/201702/201703/201704/201705/2017continues....
Next the macro will format the graph but i cant find a way to arrive at the X Axis minimum and Maximum Scale limits, if i use the "auto" function then the graph does not display until I reduce the Min and Max date number to either side of the actual date range. I thought i could use the DATEVALUE function to set the date value number as an integer and use that in the MIN and MAX graph formatting Axis code: "ActiveChart.Axes(xlCategory).MinimumScale = 42817" and "ActiveChart.Axes(xlCategory).MaximumScale = 42823". Replacing the number with the Integer for the start date and end date of my range.
Im trying to format columns based on an start date and an end date. I've been able to insert a start date and get the following months to populate by using =EOMONTH($A$7,C$1) A7 being start date and row one being by number of months following. As it is now i have add or subtract columns manually to get to the correct end date. Then if i change the beginning date all the cells formatted below are in the wrong months.
I just found your blog and am amazed at the detail and depth of your responses! Quite impressive! I want to create a macro for entering payment data into certain rows of column M (where each row is one day) based on options from a drop down menu (accessed when any cell in column M is right clicked) and based on the date in column A. The drop down menu options are: amount, start date, frequency (1 week, 2 week, 4 week, monthly), and number of payments (max 500). If the entry falls on a weekend, it should be moved back to fall on the Friday before. The first entry will be on the same row as the row of the date in column A and the remaining entries similarly. I know this is fairly complex and thank you so much for your help!
i have a problem in excel that is when i am entering 1-1, 1-2, 1-3 ,....... 1-11,1-12 it is converting into 01-jan, 01-feb,...... 01-nov, 01-dec . How to convert them into numbers when i am entering 1-13 it stay in 1-13
I love your tutorials! I do have a question though.I have a documentation sheet that has "Move In" dates and "Move Out" dates for renters in their own separate columns. I also have a column that counts the days from the date that they first move in. For example Move In Date is 12/25/2016 so the current number of days in house according to today's date would equal 25. However the formula I am using currently continues counting from the move in date to the current date (today). How would I get my counter to stop counting based on the move out date and retain the counting ability?

Hi I am trying to create a spreadsheet for vehicle finance showing vehicle, purchase date, purchase price, total interest, number of monthly payments, number of payments remaining, monthly payment, outstanding finance.
For the past year I have been using a formula to keep track of when my patients are due for their next visit. For example, if I visited today and they are due again in 4 weeks, I would plug in today's date and the formula gave me a date 28 days from today. The formula I was using was =SUM(column and row of today's date,number of days to next visit). So it might look something like this: =SUM(C3,28). That was working well up until a few weeks ago when all of a sudden, the projected date was coming up as a series of pound signs (#########). Has something changed with Excel?
