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?
I have a date stored in a variable and I need to add month(s) to that date. For example if I have 10/1/2013 in a variable if I add 1 to that month the result should be 11/1/2013. I am using the following formula but the problem is in the result date format, which shows as 1/31/1990, if I add 2 to the original date, the result is 2/29/1900 which ideally should have been 12/1/2013.
My formula is :
ActiveCell.Value = "=date(year(" & last_date & "),month(" & last_date & ")+" & i & ",min(day(" & last_date & "),day(date(year(" & last_date & "),month(" & last_date & ")+" & i & "+1,0))))"
Any other formula to add months to a given date?
Three columns.
A - Date last checked
B - Due Date
C - Actual Date checked
Currently column B simply has =A+84 and will display a date 3 months in future.. Great..
However now i want column B to still display the 3 month date - unless there is a date in C, whereby i want B to then display OK. SO what im sort of needing is =A+84 (or if somethings in C then "OK")
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"
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.
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
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%.
I have added 3 tables data .. also I had created a sample solution calc for emp1 and project1 ... I need to calculation the ratio between the months based on the working days and allocate the efforts accordingly.

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.

I'm trying to make a formula that will calculate the average of the previous 12months. The goal is to tie the formula to a reference cell that contains a date. Each time the date is changed by a user the calculation will be updated accordingly. Here is the CSE formula that I thought would work:
{=AVERAGE(IF($B$5:$B$53=B$2,OFFSET($C$5,(COUNT(C5:$C$53)-1),0,12,1)))}
I've also attached a sample file to illustrate the problem. The 'range' portion ($C$5,(COUNT(C5:$C$53)-1)[/b]of the Offset function was setup simply to get the 12 months which preceeded the reference date.
I need to automatically calculate the number of months a deal runs through 2012 dependant on the start and end date.

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

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 2013 = 2
How can I write a formula to give me the answer of 6 & 2 from the start and finish dates?
In one column I'll have a list incrementing in 1w,2w,3w,1month and I want to be able to count the number of days that have elapsed till the latest cell. Right now I'm just winging it by saying there's always 31 days in one month using a COUNTA function, but I need it to be accurate.
View 9 Replies View RelatedI am looking for something to calculate values based on the past three months. I already have written a macro to retrieve all of the data and just need this as an add-on.

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.

I'm working with 2 date columns and trying to filter a view to only include projects with dates within 3 months of today's date.
I've attached a current working file of the data and the end result i'm hoping to achieve via a macro of some sort.
I've manually got it to work via formula by inserting 2 additional columns (highlighted yellow) which determine if the dates "YES" fall in this 3 month time frame of "" blank if not.
create a macro which does all of this automatically without modifying any columns if this is possible
I want to display the percentage of occupancy for each month for condo rentals.
I have columns with dates that represent bookings throughout the year. check in and check out dates to be more precise. (A1 and B1 for example) and I have columns with months Jan, Feb, etc. (C1, D1, etc. for example)
The problem I run in to is that I can calculate the number of days between the dates and the fraction of the year (*12 to get a monthly value, but I fail to understand how I can break that up so that I can populate each month with a correct percentage of the total term.
E.g. A1=1-jan-2014 and B1=20-jan-2014 is an easy one because it only covers 1 month:
formula: =(YEARFRAC(A1,B1,3))*12 gives me 62,47% which I could just use as is for that month.
So far so good, but when the period covers more than one month or when the months overlaps, I don't know how to break the outcome up into the appropriate months to display the correct percentage for each month in its own column.
e.g. A1=1-jan-2014 and B1=20-Mar-2014 gives me a result of 253% with the same formula.
100% for November, 100% for December and 63% for January, which I could somehow formulate to break up over different Months.
But then it gets more tricky. What if the booking starts on a day other than the 1st of the Month?
e.g. A1=5-jan-2014 and B1=20-Mar-2014
The result of the formula (243%) is correct, but isn't sufficient to put the correct percentages for each month in their respective column.
What formula(s) should I use to break down the percentages to match the correct fraction of each individual month?
I attached an example of what I have so far for your review : test.xlsx
I have collected some data on economic factors for different countries. Unfortunately, the dates when I started to calculated my economic factors are different for each country (due to the data available to me).
What I would like Excel to have done is to take the date when I started to measure for e.g. country A (D3 ie 30/06/2007), copy it into column "I" (for country A, it's cell I3) and fill in the following months in the rows below (with always the date of the last day of a month) until it reaches 28th of Feb 2013. Then, it should go up to the next country (country B) take the starting date (D4, ie 31/07/2007), go to the last entry in "I" (ie I71) and paste the date in, fill in the months until 28th of Feb 2013, do the same for country C and so on.
I have started to code a VBA but I am unfortunately a beginner in VBA and totally stuck at the moment. My VBA code does paste in the months but for some reason, it also changes the starting date of the first month.
Moreover, I tried a workaround for the fact that Excel doesnt know when to stop; ie I introduced a "monthdiff" variable which should calculate the number of months between the starting date (which is variable and unique for each country) and the end date (which is always 28th of Feb 2013). At the moment, it only does this for country A.
VB:
Set rng = ActiveSheet.Range("I3" & Cells(monthdiff, "I").Address)[SIZE=4][/SIZE]
I have tried to make this dynamic but have been unsuccessful so far.
Spreadsheet with data&code is attached.
VB:
Sub Macro1()
Dim mainrange As Range
Dim rng As Range
