## 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.

## 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

## 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"

## 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?

## 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.

## 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.

## 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.

## 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.

## Formula To Indicate How Many Days Fall Within Series Of Months

## Formula Showing Revenue Recognition Based On Days And Months

Mar 15, 2014

I know I will earn \$5,000 of monthly revenue from a client. \$5,000 is represented in a monthly revenue cell. I have 12 columns showing the 12 months of the year. There is an additional cell showing the customers implementation date.

If a company's implementation date is on or after the 15th of the month (example: 3/28/2014) then the next month (April 2014) is skipped and the \$5,000 is returned to columns May through December. All months prior to May return \$0.00. If the implementation date is before the 15th day of the month (example: 3/13/2014) then the next month (April 2014) and all months after will return \$5,000. All months including March and prior must return \$0.00. If the implementation date is unknown then 12/31/2099 would be in the implementation date cell and \$0.00 is returned for all 12 months.

Essentially, if the implementation date is prior to the 15th of the month the revenue will show as of the following month. If the implementation date is on or after the 15th of the month the revenue skips the following month and will show the month after.

## 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.

## 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.

## 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".

## 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.

## Formula To Calculate Percent Change, Varied By Amount Of Months

Jul 24, 2009

I need to figure out a formula for cell F17 that will calculate a percentage change only for the months that have data in 2009. The way it is set up right now I have to go in every month and change the cell reference of the formula to include the latest data. Since the 2008 data is totally populated the formula gets messed up if I include the months of 2009 that have not yet occurred.

## 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.

## Formula To Calculate Days?

Apr 22, 2014

I am currently using the following formula which has been working great for what we needed it to do:

=IF(ISERROR(NETWORKDAYS(O34,Q34,Holidays!C\$2:C\$20)-1),"Not Completed",NETWORKDAYS(O34,Q34,Holidays!C\$2:C\$20)-1)

The formula determine what was been completed on the previous work day. If it fell on a weekend or a holiday specified in another table, it would consider it the following weekday's work. However, the needs of management have changed and they would now like to see anything completed on a weekend or holiday push back to the previous weekday and I'm not exactly sure how to modify this formula to do that.

As an example, work was completed over Good Friday. Yesterday (Monday) when we ran the report, none of those showed up in our list of completed items until today (Tuesday). They would have liked those numbers to be included on Monday's report to get an accurate picture of work that was completed.

I have attached some sample data. Everything completed on the 18th, 19th is counted as 1 day behind but we would like 18th and 19th to be shown as 2 days behind, just like April 17. That way, if we ran the report today and set the filter to 1 (for column C), those items would not show up, but they would have shown up on yesterday's report.
