This establishes “14” as the day of the date in D2. The RIGHT function looks at cell C2 and takes the first 2 characters starting from the very right and moving left. In cell B1, type the start date, including month/day/year and time using either a or p for AM and PM. Because the formatting of D2 set to Date, the “0” isn’t included in the final result. The new format will be available when you need it in the Type list. For example I need the date that is 120 days from January 1st. This establishes “03” as the month of the converted date in cell D2. I am looking for a formula that will add 120 days to a date and come up with the new date that is 120 days later. It starts at the 5th character, and then takes 2 characters to the right. This establishes “2014” as the year of the converted date in cell D2. The LEFT function looks at cell C2 and takes the first 4 characters from the left. Once you hit enter, Excel will automatically. =DATE(LEFT(C2,4),MID(C2,5,2),RIGHT(C2,2)) To find the number of days between these two dates, you can enter B2-B1 (without the quotes into cell B3). To convert it into a date, the DATE function was used in conjunction with the LEFT, MID, and RIGHT functions. For example, in the following illustration, cell C2 contains a date that is in the format: YYYYMMDD. If this is the case, you can use the DATE function to convert the information into dates. This is may be because the numbers don't resemble a typical date, or because the data is formatted as text. But sometimes the dates aren't recognizable. If you open a file that came from another program, Excel will try to recognize dates within the data. For example, DATE(2008,1,-15) returns the serial number representing December 16, 2007. If day is less than 1, day subtracts the magnitude that number of days, plus one, from the first day of the month specified. For example, DATE(2008,1,35) returns the serial number representing February 4, 2008. If day is greater than the number of days in the month specified, day adds that number of days to the first day in the month. A positive or negative integer representing the day of the month from 1 to 31. For example, DATE(2008,-3,2) returns the serial number representing September 2, 2007.ĭay Required. If month is less than 1, month subtracts the magnitude of that number of months, plus 1, from the first month in the year specified. For example, DATE(2008,14,2) returns the serial number representing February 2, 2009. Theres no built-in function in Excel that can do this. If month is greater than 12, month adds that number of months to the first month in the year specified. An easy formula that returns the day of the year for a given date. A positive or negative integer representing the month of the year from 1 to 12 (January to December). Because Excel stores dates as whole numbers, it’s very easy to calculate the difference between two dates. If year is less than 0 or is 10000 or greater, Excel returns the #NUM! error value. The simplest and most common method of calculating the number of days between two dates is to subtract the latter date from the former date. If year is between 19 (inclusive), Excel uses that value as the year. For example, DATE(108,1,2) returns Janu(1900+108). Add Days to a Date Dates in Excel are stored as serial numbers where each whole number represents a unique day: This makes adding or subtracting dates extremely easy. If year is between 0 (zero) and 1899 (inclusive), Excel adds that value to 1900 to calculate the year. For example, "07" could mean "1907" or "2007." Four digit years prevent confusion.

Just check that you are doing it the correct way. What this means is that when you are doing date calculations in Excel, to be human correct, you will probably need to either add or subtract one. But when it comes to dates humans tend to assume a different process. If I asked you the answer for 31 minus 1 you would have no problem with the answer of 30. But humans have become accustomed to assuming that the calculation is from the START of the first date till the END of the last date. beginning of the day or end of the day on BOTH dates. Excel is assuming that each day is at the same starting point e.g.
