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"

Formula To Calculate Based On Start Month Number And Duration Number Of Months

Mar 14, 2014

I need a formula that will calucalte the monthly total based on the following conditions:

Col A = Yearly Cost
Col B = The number of the month when the costs are starting (1=Jan etc)
Col C = The duration or the number of months for which the costs are to spread
Col D is Year 2013 with the months across columns D-O. Row 1 above those columns shows the month's corresponding number.

Adding # Of Months To Calculate A Date

Jul 30, 2007

Is there a way to add # of months to a date and then find out what would be the exact date?

For example if cell A1 = 04/30/07 and Cell B1 = 14 what is the statement that would give me 06/30/08 in Cell C1?

Also, how can I modify the statement if Cell B1 = 14.5 to get 07/15/08?

Calculate Date Six Months From Cell Date

Jan 25, 2010

I have a start date for a contract in cell AM1. I need AN1 show a date six months from the start date in AM1. I am fine with that part.

However, I would like for AN1 to calculate not only a six-month date but also to auto-update to the next six month date from AM1 once the first six month date is about, let's say, one month past. What I am doing is calculating when a six-month inspection needs to be completed; these inspections are ongoing, so I need them to auto-update.

So let's say a contract was awarded today, 25 JAN 2010. That would be value in AM1.

I want AN1 to produce a date six months from 25 JAN 2010, which would be 25 JUL 2010 (yes, this way of calculating the six month date is fine). Then around, let's say, 25 AUG 2010, I want AN1 to auto-update to produce the next six month date, which would be 25 JAN 2011 (six months from 25 JUL). Obviously the function would need to relate to TODAY() in some way.

Calculate What Months An Employee Worked By Start And End Date

May 15, 2009

I am working on a sheet that will allow a user to enter a start month (from a pre-defigned drop down list) and an end month (again from ddl). What I need to calculate is in what months the employee worked in so I can calculate their salary cost by quarter.

It can populate other cells in order to do the calculation if needed. So, for example if an employee started in May, and worked until December, I need to calculate that he worked 2 months in Q1, 3 months in Q2, 3 months in Q3, and 0 months in Q4. Our fiscal year is April to March.. ;-) I have thought of several options, but none of them have worked 100%.

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.

Number Of Months In Year 2007 From Date Range

Jan 12, 2008

I have a "start date" and an "end date". Is there any way to tell how many months are included in 2007 from those two dates using a formula? For instance, from 01-Feb-04 to 01-Feb-07, there is 1 month in 2007 (January). And likewise, 01-Jan-05 to 01-Jan-08 there is 12 months in 2007.

As noted, I have the start and end dates. I don't have the "how many months in 2007".

Start Date End Date How many months in 2007
01-Feb-0401-Feb-07 1
01-Jan-0301-Jan-06 0
01-Apr-0401-Apr-07 3

Calculate The Quarter To Date Number

Aug 19, 2007

I was given the formula below to calculate the quarter to date number. The months from 1/1/05 thru 12/31/07 are in cells C3-AL3.

First - can anyone explain the formula so I may understand it and possibly modify it for other uses

Second - wherever the formula has 3:3 and I copy it to the next cell below it, I have to change the 4:4 to a 3:3 - any suggestions on how to do this easily.

By the way, the formulas are in column AO, staring on row 4.

=SUM(OFFSET(A3,1,MATCH(DATE(YEAR(Date!$C$6),INT((MONTH(Date!$C$6)+2)/3)*3-2,1),3:3,0)-1,1,MATCH(Date!$C$6,3:3,0)-MATCH(DATE(YEAR(Date!$C$6),INT((MONTH(Date!$C$6)+2)/3)*3-2,1),3:3,0)+1))

How To Calculate The Week Number Of The Month Based On A Date

Dec 30, 2013

I would like to calculate the week number of the month based on a date.

Now my days would only include working weeks (Monday - Friday).

Supposed the date is 12/31/2012:

M
31-Dec
T
1-Jan
W
2-Jan
TH
3-Jan
F
4-Jan

Since it only occupies 1 day of the workweek, then it will be considered as Week 1 of January. If the date is 1/28/2012:

M
28-Jan
T
29-Jan
W
30-Jan
TH
31-Jan
F
1-Feb

It will be considered as Week 5 of January since it occupies 4 days of the working week. If the date is 4/29/2013:

M
29-Apr
T
30-Apr
W
1-May
TH
2-May
F
3-May

It will be considered as Week 1 of May since it occupies only 2 days of the working week.

Basically if the date's month occupies 3 or more of the working days of the workweek then it will be considered as part of that month's working week. Is this possible with formulas? I tried to explain it the best I can.

Calculate Number Of Days Between Invoice And Today Date

Feb 21, 2014

I'm trying to create a new column which calculates the number of days from the today's date to the due date of an invoice. Also a Column that an invoice is/was overdue.

Column A - Clerk inputs date that invoice was received
Column B - Clerk inputs the date that the bill was paid
Column C - Auto populates the due date of the invoice (20 days after the invoice is received)
Column D - I want a number of days to auto populate based on today's date that will show how many days we have to pay the bill. Example: today is 2/19/2014, bill is due 2/22/2014 (Column C), column D should read 3 (I would prefer is the number is black for "we have days left to pay", red for "we're behind")
*Extra bonus for Column D, if the column goes blank after a date is entered into Column B* - but not necessary

Column E - I would like if the date the bill was paid (Column B) is greater than the date the invoice is due (Column C) to show "Overdue" in the cell.

Calculate Age In Months

Nov 9, 2009

I need to be able to calculate age in months, and round whatever remainder to the middle of the month (.5). I am calculating z-scores and percentiles for in a childhood obesity project. The DoB and Date of measurements must be converted to read anything from 142.0 to 142.9 as 142.5.

This value will be used to look up the the appropriate LMS (Box Cox, Median, and Standard Deviation) in another excel table. I have to be able to compute age in months so 142.5, 143.5, 144.5, 144.5 etc. It is just not rounding off to the nearest half month.
