# Calulate The Number Of Years And Months From A Specific Date

Jan 22, 2009

I would like to calculate the number of years and months that have passed since a certain date. Would like it in a number format so I can pickout those who have gone reached 5 year increments during each month.

Such as someone reaching 40 injury free years in June of this year I can let them know.

## Summing Values For Specific Months And Years?

Mar 27, 2014

I will set a base example first:

9 Nov 2012 Apple 5
12 Dec 2012 Apple 3
14 January 2013 Banana 8
17 January 2013 Apple 6
20 January 2014 Apple 3

I would like a sumifs formula that will only add the results for Apple - as follows:

Nov 2012 5
Dec 2012 3
Jan 2013 6 (i.e. does not include Banana - and also does not include Jan 14 Apple)

Although I have experience with sumifs I have not been able to use the correct syntax to identify the month AND year.

Ultimately I want to look through many hundreds of dates, and add anything that fits two criteria - 1) a 'name' criteria, and 2) it falls within a certainly month and year.

## Adding Years, Days, Months To Date/time Format

Apr 26, 2007

I have some cells which must be in the format 15/06/2007 15:25

I then need to add either days, months or years onto it.

Say the above date/time is in cell A1, when I do =YEAR(A1)+5 it displays 2012 if I choose the general cell format, but when I select the same cell format (date time) it comes out as 04/07/1905 00:00

## Add Months & Return Decimal As Years & Months

Jul 31, 2007

I am looking for a formula that will add months and return the year. E.g. if I add 1.05 and 1.07 I should get 3.01. i.e. 3 years and 1 month.

## Display Number Of Years Based On A Date

Mar 28, 2009

Right now, in a column I would like to display an number (length of employment) based on the hire date.

In one cell the employee's hire date is entered. In a column of other cells the pay period ending date is displayed and in another column the length of employment is displayed.

Example:

03/17/2000

03/01/2009 8
03/15/2009 8
03/29/2009 9
04/12/2009 9
04/26/2009 9

How would I create a formula in the length of employment cells that would indicate the correct number of years based on the hire date and adjusts when the pay period date passes this hire date?

## Date Formula; Gets To 2 Years & 11 Months The Cell Will Go "YELLOW" For 1 Month Only Before It Turns "RED"

Jan 24, 2009

I have a file that uses dates, when a cell is in date the cell is "GREEN" but when the cell is out of date after 3 years it turns "RED". I want to add another formular so that when it gets to 2 years & 11 months the cell will go "YELLOW" for 1 month only before it turns "RED".

## Calculate Number Of Months In Specific Year Between Two Dates?

May 19, 2014

I am trying to calculate the number of months in a specific year between two dates.

For example.

Start date 01/06/2012
End Date 01/02/2013

Number of months in 2012 = 6
Number of months in 2013 = 2

How can I write a formula to give me the answer of 6 & 2 from the start and finish dates?

## Adding Years To A Date (taking Into Account Leap Years)

## Concatenating Months And Years

Oct 14, 2009

I'm attempting to concatenate lines 86 and 87, month and year together.

The formula I use is: "=C86 & C87" - but I get a large number instead of "October 2009"

## Months To Years Conversion?

Apr 4, 2012

I have been trying to figure out a formula to convert the amount of months in a certain cell to years.

I have come up with:

=INT(E29/12)&" years "&MOD(E29,12) & " months"

The problem is it comes up with 2 years 3.37063951499227 months

How I change it to come up with 2.4 months, round it to the highest number instead of loads of decimal places? I have tried change cell E29 do 0 decimal places but it doesn't work.

## Calculate Age In Years And Months

Oct 5, 2006

I was asked by a colleague how they could put a persons date of birth in one cell, todays date in another, and return their age in years and months. Accuracy to within a month. This is what I gave them.

=TRUNC((B1-A1)/365.25)&" Years "& ROUND(((B1-A1)/365.25-TRUNC((B1-A1)/365.25))*12,0)&" Months"

## Years & Months Between Two Dates

Which formula should I use to return years and months between two dates.

4/1/05 7/30/25

## Formula For Months To Years Conversion

Aug 14, 2009

Here is my formula:

=E3*(1+E9/365)^(365*E5)

Cell E5 contains a place for you to put in the number of years you want

I want to modify this formula so that it calculates months instead of years, but still be based of a 365 day calendar year.

## Multiple Months And Years In One Cell

Dec 13, 2011

Is there a way to show in excel that something feel within a specific time frame? An example being if I want to see the amount of time it took to close a customer service ticket. I would take the closed date minus the raised date, but then I would like to show in a cell it was open from Feb to Mar 2011.

## Calculating Years And Months With Blanks

Jan 8, 2014

Was needing to calculate years and months returning it such as 2.10 if 2 years and 10 months.

And also if left blank would not return any value. (There might not be a date yet in H3 in some cells.)

G3 thru G1000 has the hire dates. H3 thru H1000 will be the cell for the formula.

## Calculate Day, Months & Years Between Dates

Dec 20, 2006

I have two columns with dates (and times) in that I am trying to define how many days, hrs and mins have elapsed i.e. A1 has 12/12/06 21:00, B1 has 17/12/06 21:00. C1 has B1-A1 and is custom formatted to show as dd"days" hh"hrs" mm"mins". In this case it will therefore show as 5days 0hrs 0mins. Which is correct.

However, if more than 1month has elapsed then the format m"m" d"days" h"hrs" m"mins" does not work. For example 17/03/06 03:00 to 20/12/06 07:00 shows as 10m 4days 4hrs 00min, which it clearly isn't.

I know the reason it does this is because it calculates the difference between the two times and adds that to it's 0 value, which in my format is 01/01/1900 00:00. therefore when it adds 277days (the answer) it becomes 04/10/1900 04:00, so my formatting is just calling the month value ('10') and the day value ('4').

I understand the reason it does this, 277 days on from 01/01/1900 is indeed Oct 4th, but 277 days on from 17/03/06 is not 10months and 4 days as there are different length months in between. It also seems to add a month on, possibly because the format for 'months' is between 1 & 12 and therefore cannot begin at 0?

Does anyone know if it's possible to force excel to work out the correct number of months and days have elapsed between two dates and not apply it to 01/01/1900? Or any other possible solution, maybe with a different custom format?

## Calulate Age: Find Out Over Aged Students By Date Of Birth

## Calculating Years / Months / Days Between Two Dates?

Oct 17, 2009

## Formula To Spread Costs Between Months And Years?

Dec 3, 2013

See attached. (I added in some arrows for the first month so it is easier to follow the logic)

I am working with monthly revenues. Revenues are earned in a specific month but only a % is received in that month and over the next 4 months. I need a formula that will spread these revenues earned in 1 month over the next 4 months.

Currently, I have a complex Index/Match formula which works until September. September, October, November, and December do not work correctly because once the months roll over from month 12 (December) back down to month 1 (January), my formula cannot recognize the range.

Essentially, I need the formula to return the correct amount that is being paid, even across different years.

I don't know if my formula can be modified or a new formula would be more efficient.

## Calculate Averages Of Individual Months Over 40 Years

Jan 5, 2012

I have a large sheet of daily river flows and precipitation amounts, over 40+ years.

I want to calculate the average flows in each month of each year (ie 11/1968, 12/1968, 1/1969 etc). Dates are in Col A, flows in Col D.

How to average a particular month over all years like so:

{=AVERAGE(IF(MONTH(A2:A15282)=1,D2:D15282))}

But I don't know how to average per month of each year, or how to make a formula that will allow me to quickly calculate the averages of 100s of months.

## Getting Total Months In Between Dates (disregarding Years)

## How To Change Formula For Calendar To Show Months And Years

Apr 1, 2014

I have come accross this calendar online and it suits my requirements, however, the month s currently static and the year is dynamically controlled by a spin button.

The formulas in the relevent days are as follows

Day 1 =IF(AND(YEAR(JanOffset+1)=calendarYear,MONTH(JanOffset+1)=1),JanOffset+1,"")
Day 2 =IF(AND(YEAR(JanOffset+2)=calendarYear,MONTH(JanOffset+2)=1),JanOffset+2,"")

and so on, I need the formula and the spin button the also change the month as well as the year.

Please see attached file for details.

## Calculating Difference In Months Between Dates / Ignoring Days And Years?

Mar 13, 2012

Cell A1 contains 02/29/2012

Cell B1 contains 12/01/2006

I am looking for a formula that will return the number of months (periods) between two dates, ignoring days and years. Using the above dates, which cannot be changed, the result needs to be 63. The formulas I have tried keep returning 64 because my later date is at the end of a period, and my earlier date is at the beginning.

## Calculate Number Of Months Between Two Given Date

Apr 12, 2006

Start date: 12/04/2004
End date: 12/04/2006
The formula should give the answer to 24 months

Example 2
Start date: 12/04/2004
End date: 13/04/2006
The formula should give the answer to 25 months

When I use function =(YEAR(A4)-YEAR(A3))*12+MONTH(A4)-MONTH(A3), it does not
show 25 months for "Example 2" as it is still within the same month "April"

## How To Translate Number Of Months Into Future Date

Dec 9, 2009

I've developed a spreadsheet in Excel 2000 where one of the cells contains the number of months a quantity will last, calculated by taking the total amount and dividing it by the amount used each month (a constant).

I would like to have another cell where that number is translated into the future date that number of months represents, so that in addition to seeing how many months the total amount will last, one can see when the amount will be depleted.

For example, suppose it is December 9, 2009 (as it is now) and the number in the number-of-months cell is 6. Then, is there a way that when 6 is calculated, in another cell appears something like June 9 2010 or 6/9/2010 or 6/9/10 (assuming the computer's clock is correct)?

It would be nice if the formula would handle decimals too, such as the date for 6.4 months, but that's not essential.

## Lookup Query - Occurrences: Create Another Worksheet With The Months Of The Years Listed Down Column

Oct 16, 2008

I have a table that lists the months of the year down from cell A2:A13, and days of the week along row from cell B1:H1. The data in between (cell B2:H13) is pulled through from elsewhere in the workbook and is in number format.

What I basically want to do is create another worksheet with the months of the years listed down column A, and in column B, for each month, I want the first day of the week where the value in the original table is more than zero, and in column C the second day of the week where the value is more than zero. I really hope that makes sense, was quite difficult to explain!

## Formula To Change Date To Number Of Months Worked

Sep 30, 2011

Just wondering if there is a formula where I can change the date an employee started working into the number of months employed??

Example, John Smith started here in January 2011. I would like the formula to return 8 months.
