# Calculating Days,Dates And Years

Feb 4, 2010
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..

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.

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.

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 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.

Input Data

Start Date

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.

I need to create variables that splits out a length of stay across years and enters the number of days in each of those years into separate year variables. Below are two sample cases:

CaseID StartDate EndDate

222 12/23/1988 01/01/1997

22112/25/1989 2/12/1990

After creating different variables for the different years, in this case: 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, I want to be able to pull out the number of days that goes into those years as separate variables.

Thus

caseID daysin1988 daysin1989 daysin1990 daysin1991 . . . . 1997

222 9 365.25 365.25 365.25 0

221 742

and so on

I have 2 dates and I'm looking to distribute the days between in the correct 'year' column (See below). my problem is with the units that have days that span +2 years.

I've tried nested 'If(and...)' formula......

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"

C7 3/24/04

D7 1/4/08

I've got daily water level data that spans around one hundred years. I am looking for monthly average water level data, but rather than using the whole month, I'd like to average the first two days and the last two days. I want to have a single value for each month in the 100 years of data.

If the data was smaller I could do this by hand, however having 100 years worth of data = 1200 months = so many days...

It's tough since months don't have a set number of days, and then leap years and it all gets so complicated. I've never really had a problem where date was a criteria to pull values from, and I don't know how to work with this. The internet suggest the Averageif function which I have dabbled with, but no dice.

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 have list of dates:

e.g: D/M/Y

1/03/1997

22/05/2005

13/09/1945

I want a new list that just shows the year and is formatted as a number

e.g:

1997

2005

1945

Is there a way of doing this without doing it manually, I have 20,000 observations.

I have two dates, one is a start date the other is todays date, I want to subtract the start date from todays date and show the number of years. But a small twist is I only want to take the years away from each other, ignore day/month. Start 01/05/2000 todays date 01/10/2008 years = 8. Start 10/10/2000 todays date 01/10/2008 years = 7, want it to still show 8 years and ignore the start day/month.

I have a list of people with birthdays that needs to be checked against TODAY to determine how old people are. If I subtract the two fields from one another, I get number of days. But is there a way to convert into years? In my attached example, I'd like column C to display 3 (age for person).

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 mutliple non-contiguous columns that are SUPPOSED to contain dates. If the particular item for that coulmn doesn't require a date then "waived" is typed; others may be blank. I want to apply a filter that will tell me if any one of the columns YEAR is older than "2004". I'm really bad at formulas to bare with me.

I inserted the following formula: =IF(OR(YEAR(N6)<=2004,YEAR(V6)<=2004,YEAR(X6)<=2004,YEAR(AB6)<=2004,YEAR(AD6)<=2004,YEAR(AF6)<=2004,YEAR(AI6)<=2004),"EXPIRED","GOOD")

The problem is that if the cell is blank or if contains "waived" it either produces "#value!" or it reports "True" when it is actually "False". I'm not sharp enough to know how to account for those two conditions in my formula.

I am using 2010 to write some code for a spreadsheet that will be used in 2007, so I know that RepeatLabels is not available.

My question is if you Group a date field by Months and Years and the data spans across 2 or more different years, is there a way to hide months in a specific year? I ask because the Date field has only 12 months in it and if I hide Jan (for example) it hides Jan in both years. (attached pic of filter for Date field below.)

Is there some other way to format it so it can discern between years or do I need to add yet another column to my original data?

I am trying to capture the number of years/quarters are between two dates - giving credit for one day worked into the quarter.

In the attached png file you can see the formula I used for column J. This is the same formula I need to use for Column R but now using 10/1/11 and the date provided in Column R. The formula should be used in Column S "Part B" so that I can determine the number of years between 10/1/11 and the date in Column S.

Here is my set up:

A2 to BF2 is a range of dates

A3 to BF3 are sales. Days without sales are 0.00

I want to pick a range of dates and find the number of days without sales between those dates. So, a formula that will look to a start date in A1 and an end date in B2, and then count the number of days that did not have sales between. Index/Match/Countif/Dateif I can't seem to make anything work.
