=wherexldate+45

*xldate*is the named reference to a standard Excel date.

**Adding months to a date**is almost as easy. Let's say you want to add 5 months to today's date (8/11/2005). The formula is

=DATE(YEAR(This formula works because 13/11/2005 is correctly changed to 1/11/2006. So, you don't have to worry about the problem with the year changing.xldate),MONTH(xldate)+5,DAY(xldate))

**Update:**

Although a bit lengthy, the following formula can be used to add

*n*months. If the original day is greater than the number of days in the new month, then it will return the last day of the new month.

=IF(DAY(xldate) > DAY(DATE(YEAR(xldate),MONTH(xldate)+n+1,1)-1),

DATE(YEAR(xldate),MONTH(xldate)+n+1,1)-1,

DATE(YEAR(xldate),MONTH(xldate)+n,DAY(xldate)))

I tried the formula and it works except when the date is, for example, January 29 and the next month to be added is February (non-leap year). It would have been better if it calculates the last day of the month. But the figure displayed is March 1st. Is there a special formula for month ends that conerns February? Thanks.

This problem also occurs when you add a month to 3/31/2005, resulting in 5/1/2005 instead of 4/30/2005.

I updated the original post with a formula to solve the problem.

just use =edate(date, months)

EDATE is a function that is available in the Analysis ToolPak add-in

Hey... thanks lot. I just use =edate(date, months). it works fine. hassel free. No need if conditions. Just go in excel menu -->tool>add ins..> analysis toolpack. The edaye funtion will display in your date time functions list. Its work like ADD_MONTHS in pl/sql.

EDATE is only available in Excel 2007, or if you have a toolpack add-on.

Amazing! Thanks a lot! Who needs MS Help when you have Google!

I WANT 24/05/2005+60 MONTHS

24/05/2005+60 MONTHS is easy:

say cell A1 is 5/24/2005.

enter the following in cell B1:

=EDATE(A1,60)

if you see 40322, then format the cell as date, you will see 5/24/10

what about if you try to add 8 1/2 months to any date

Just put -1 at the end of your formula to get last day of the previous month

thank you sooo much...

Let's say you needed to generate a date end of month after the cell's information. Say Cell A1 = 12/01/2011, and you want Cell A2 to view as 01/31/2011.

I want to calculate the retirement date from the Date of Birth, will it calculate leap year or not. Kindly clarify?

Edate Formula is Best..!

how can I add a month to a date from another worksheet?

Does anyone know how to write a formula that adds 1 month to the initial input date, then two months to that date, then six months to that date, etc?

Spot on!!I had to send a report and i needed to know how to add 6 months to the existing date....found the solution here! and report was ready in 5 mins!! thank you! Ann

Using the Edate formula I'm trying to add 144 months to say 30/03/2002, yet the cell comes up with #VALUE!

Using the same formula and cell formatting, I do the same for 05/07/2022 and it comes up correctly with 05/05/2034.

What am I doing wrong despite using the same formula??

I need to add Cell B2 which worked out to 6months to a date formula:

=DATEDIF(B26,B27,"y")&" years "&DATEDIF(B26,B27,"ym")&" months "&DATEDIF(B26,B27,"md")& " days"

How to add 6 months to a date without showing the date

like 26/5/2013 will appear as Novmeber 2013

THANK YOU! Update was exactly what I needed.

=DATE(YEAR(C5),MONTH(C5)+5, DAY(C5)-1)

this did the trick of adding 5 months to the date. It adjusted the year even though my formula doesn't address it.
