Calculating Years / Months / Days Between Two Dates?

Oct 17, 2009

my spreadsheet is setup with two dates: A date for when someone joins our group A date for when they are released/leave

I want to be able to see exactly how many years/months/days transpired between these two dates. I have tried lots of different formulas with no success.

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.

I recently manage to create a spreadsheet. On the spreadsheet what I am looking to do is once I change the year in cell U1 from 2010 to 2011 to automatically change the days and the date number, and where Sat and Sun preferably to auto-fill in yellow the whole column within the table as you can see in the spreadsheet.if not then just do not display Sat/Sun columns at all..

I am using the following formula to calculate years months and days in Excell 2007 =DATEDIF(C7,D7,"y") & " yrs, " & DATEDIF(C7,D7,"ym") & " mths, " & DATEDIF(C7,D7,"md") & " days"

I have a start date dd/mm/yyyy, and require a formula that everytime a spreadsheet is opened, based on the current date, to calculate how many years, months and days have elasped yy mm dd since the start date...

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

The issue is i want years and months between two dates which are not in computer language. Date like 2008/12 and 2010/01. File is attached for you reference

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?

ith the example below, i am having a problem with the calculation of Total Month. If i put Dec 31 2012 in A2 the total month is 10 BUT if I change the A2 to Dec 30, 2012 the total month is 11. What i am trying to do is to calculate the number of months only disregarding the years. example August 15, 2010 and January 16, 2013 i need to have total months of 5 months only.

I need a formula that will allow me to put a date in cell a2, and in cell a3 put the the number of days between 2 dates. Example.. For example (A2) shows 08/06/08, a3 to show the number of days from 08/06/08 to 08/14/2008--(a3 )14 and (a4) to shows the number of days from 08/06/08-10/05/2008 ---(a4) 60 days.

I am trying to calculate dates that will happen 16 days from date specified in column A (A23:A200), based off a certain entry in Column B (B23:B200), which is named in cell P5. I can get the date by doing the specified date + 16, e.g. =IF($B$23:$B$200=$P$5,$A23+16,"")

The trouble I am running into is not having the date populate until it has reached 16 days from the dates in column A, show blank if possible until 16 days from date in column A. The dates in column A will always be previous to todays date.

I have a static date and military time in B6 (5/10/07 18:00) I have to write various formulas to reflect 1 month (whatever calendar month it ends up in, so not necessarily 30 days) minus 7 days and then the same formula plus 7 days. How is this written?

I have a spreadsheet where I have an intial date of issue of a warrant. Once this warrant has been executed, then a further column is populated with the date. The data I need to work out (Preferably without using macros if possible) is, if there is no execution date the length of time from issue to todays date, but if there is an execution date then length of time from issue to execution. I can do either on their own, but i would like to have only one column showing this info and if possible to update each time the sheet is opened

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.

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"

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.

I wanted to determine the number of days between two dates. Specifically, if the initial date is in one month, and the second is in a different month and an output would result a number of days in each month until the final date. BUT I have a large amount of data to do this for in a list view, way to put a formula in excel and just drag down the entire list to get the required information. see below for an example.

The result I'm looking for is the separate the months and only show the relevant months between the two dates in one cell or the adjacent. Something similar to the table outlined below.

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.

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.

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.

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.
