# Adding Years To A Date (taking Into Account Leap Years)

Aug 28, 2007

I have a date 07/28/2027 and need Excel to calculate a date 65 years in the future taking into account leap years.

## YEARFRAC & Leap Years

Jul 30, 2007

It looks like a pretty silly problem but it's driving me mad. The yearfrac function takes a two dates and a basis. Now assume basis = 1 ( Act / Act ) and two cases:

1) 06-Jan-06 -> 06-Jan-08 ( 730 days ) = 1.998175182 =>> divisor = 730/1.998175182 = 365.33333

2) 06-Jan-05 -> 06-Jan-07 ( 730 days ) = 2 =>> divisor = 730/2 = 365

In case 1) 2008 is a leap year ( but the "leap" has yet to come! ). Can anyone explain me the logic behind? I suppose the extra day is divided by 3 but where is the "Actuality" of the divisor?

## 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

## Adding Years To A Specific Year And Then Rounding It Up

Apr 3, 2009

There are two columns in an excel sheet, one is date of birth and other is date of reteirment

looks somewhat like this:

D_O_B D_O_R
5-Mar-53 31-Mar-11
30-Jun-57 30-Jun-15
20-Jun-51 30-Jun-09
2-Feb-55 28-Feb-13
2-Jul-51
13-Oct-55
1-Sep-51
7-Jul-54
14-Mar-53
3-Aug-50 3 0-Sep-13

Some of the dates in D_O_R are missing. I need to fill in up all the dates in D_O_R column.

D_O_R is = 58years+D_O_B(NOTE the dates should come as last date of the month)

## Date Fields Increase Date By Numbers Of Years Based On Lookup Table?

Aug 11, 2013

In column A, I have dates; In column b i have security levels. I have made a table called "Security" it contains to columns, a list of security levels and no of years when each security level is required to be reviewed. the table is setup -

d1 e1
Restricted 5
etc

Example of data
ie.
a1 b1 c1
Restricted 1/06/2012 1/06/2017

What I am looking for is a formula to look up a1 "restricted". then lookup the security table and find "restricted" its value is 5 (years) then add the 5 years to date in b1, but place it in c1.

## Display Number Of Years Based On A Date

Mar 28, 2009

Right now, in a column I would like to display an number (length of employment) based on the hire date.

In one cell the employee's hire date is entered. In a column of other cells the pay period ending date is displayed and in another column the length of employment is displayed.

Example:

03/17/2000

03/01/2009 8
03/15/2009 8
03/29/2009 9
04/12/2009 9
04/26/2009 9

How would I create a formula in the length of employment cells that would indicate the correct number of years based on the hire date and adjusts when the pay period date passes this hire date?

## Year To Date Filter - Multiple Years

Jan 11, 2013

Basically I need to add a column to my source data so I can use it as a filter on my Pivot Table in a different workbook. - something just as simple as TRUE/FALSE if the date is YTD for all years would be ideal.

Have attached an example if that makes it any clearer! nice simple formula would be ideal as sheet is around 600,000 rows long and growing!

## Auto Generate Date Today But 3 Years From Now

I need to auto generate and populate some cells with todays date but three years from now.

## 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.

## Create Year To Date Sales Comparing 4 Years Month By Month?

Dec 25, 2013

Need to create year to date sales comparing 4 years month by month. Stacked chart (Excel 2010) works OK for the first three months but adding the fourth month changes the chart to 4 series with a monthly axis. To put it another way I need a vertical axis of years and a horizontal axis of \$\$\$ with each months sales of each year stacked on its year.

## Excel 2010 :: VLookup Between 2 Workbooks Taking Into Account Duplicates On Source?

Mar 28, 2013

I've got 3 columns of formulas that end up doing what I need, but I'm thinking it could probably be done easier with VBA.

I have 1 book with a sheet I'll call Log & another book with a sheet I'll call Source. On the Log, column E has the first 9 characters of vendor names & /vendor number (ex: EDMUND FI/00250), along with other data out through column P. On Source, the vendor names are in C & a short code for their name is in A.

I need to compare the first 9 characters in Log col E with the first 9 characters in Source col C. When a match is found, I need to return the short code from Source col A. BUT - if there's a duplicate in either Source col C or A, instead I need to return the word VERIFY, preferably with the cell highlighted in red.

Right now, I have, on Source col L:

Code:
=MID(C2,1,9)
and in source M:

Code:
=IF(OR(A2=A1,A2=A3,L2=L1,L2=L3),"VERIFY",A2)
This gives me the first 9 characters of the vendor name in L & the short code OR VERIFY in M

Then, in Log col R, I have an array formula:

Code:

This gives me either the short code or VERIFY from Source M. Also, sometimes it doesn't find a match & it returns #N/A. Then I have to do Conditional Formatting to make the VERIFY cells red & I thought I'd make the error cells be yellow (although I haven't figured out the CF for that yet)

Is there a better way to do this with VBA? I'm working with Excel 2010; just got it & still figuring it out.

## Best 3 Of The Last 10 Years

Nov 4, 2008

I am working on a retirement calculation sheet. For retirement calculations the employees need to figure out their highest yearly income for three out of their last ten years. The three years can be based on any consecutive twelve months but each of the three years must be the same months, (example, Jan thru Dec, or July thru June). The three years cannot overlap.
Here is what I have so far. Column A, paydate. Column B, amount. Column C, year to date amount. Column D, amount for past 12 months.
I would like to list the three highest years in the first 3 rows of Column E.
Any help is greatly appreciated.

Pay Date Gross Year to Date Gross
Past 12 Months Highest 3 Years 08/10/06 3,594.58 3,594.58 3,594.58
08/24/06 3,332.79 6,927.37 6,927.37
09/07/06 2,595.59 9,522.96 9,522.96
09/21/06 2,457.36 11,980.32 11,980.32
10/05/06 2,457.36 14,437.68 14,437.68
10/19/06 2,457.36 16,895.04 16,895.04
11/02/06 6,212.51 23,107.55 23,107.55
11/16/06 3,206.09 26,313.64 26,313.64
11/30/06 4,104.56 30,418.20 30,418.20........

## Complex If Statement To Calculate Date Range From Create Account To Stop Account

Sep 7, 2012

Creating a formula that basically has a big IF statement. I hope this makes sense, so here goes. I am looking to find the "age" or "elapsed days" of an ID from when they created an account to when they stopped. This might be very complex and if there's not a way to calculate the Elapsed days (even though that's what I prefer), perhaps there is some formula that can return a value like a "1" or "True" or something that lets me know the statement is true.

original formula from post 3261273
{=IF(D2>0,A2-INDEX(A\$2:D\$16,MATCH(B2&"1",B\$2:B\$16&C\$2:C\$16,0),1),"")}

New formulas needed or revised from the above:

Formula 1: If the ID in column 2 are the same, and if there is a value in column 3 (Create) and a value in Column 4 (Suspend) AND there is no value in Column 5 (Stopped), then subtract the dates in column 1 for Create and Suspend. My manual calculation result is in the column called "Elapsed Days (Create to Suspend but NO Stopped)

Formula 2: If the ID in column 2 are the same, and if there is a value in column 3 (Create) and a value in Column 4 (Suspend) AND there is no value in Column 5 (Stopped) OR Column 6 (Unsuspend), then subtract the dates in column 1 for Create and Suspend. My manual calculation result is in the column called "Elapsed Days (Suspend Only, No stopped or Unsuspend)"

Formula 3: The ID in column 2 does not have to be the same, but if there is a value in column 3 only (Create) and there is no value in the Suspend, Stopped, or Unsuspend columns, then place a "1" in the cell. My manual calc is the "Create Only" column.

Event Date
ID
CREATE
Suspend
STOPPED
Unsuspend
Elapsed Days (Create to Suspend but NO Stopped)
Elapsed Days (Suspend Only, No stopped or Unsuspend)

## YTD Sum Across Multiple Years

Jan 14, 2009

I need to calculate YTD sums using the data that spans three years. I am using

SUM(B2:INDEX(B2:AC2,MATCH(\$B\$10,\$B\$1:\$AC\$1,0))). This works fine if all of my data is contained in one year. However, when my data spans multiple years it does not. For example, if I have the following and today is April 2007 I want to calculate Jan-April 2007.

## Dates, Number Of Years

Dec 15, 2008

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.

## Printing To Labels For Years

Apr 27, 2008

I created a wedding list with a bunch of fields for each household: first name person 1, second name person 1, first name person 2, second name person 2, street #, street address, apartment, city, state and zip. Then I realized that I probably needed to combine fields for each line of the address so I created 3 combined fields: 'combined 1 ' that looks like this "joe smith & patsy cline," a 'combined 2,' that looks like "14 jones street, #3," and a 'combined 3,' that looks like "New York, NY 10037."

I haven't printed to labels for years and when I did some quick research via the help function on excel it said to print labels via word...which worked fine until i got to this section: " In the Mail Merge Recipients dialog box, click any column labels in your data that correspond to the Word identifiers on the left. This step makes inserting your data in the form documents easier. For more information about matching fields, see Word Help. "

I have no idea what this means, but here's what I need to figure out: " how do I print labels using just 3 of 8 existing columns in my spreadsheet, i.e I just want to use combined 1, combined 2 and combined 3 for the 3 lines of the address. My first instinct was just to cut the contents of the combined fields into a new spreadsheet and just do it taht way, but I created the combined fields using a formula which relates to the other fields........

## Totaling Years In Cells

## Subtract X Amount Every Y Years

May 28, 2009

I am building an investing strategy model and am looking for a fomula or combination of formulae that would subtract an amount (lets say a 100) every so many years (lets say 10). Data is set up horizontaly, i want to be able to set how much will be subtracted and how often in a "control panel" next to other inputs and variables. I am not proficient in Macros and most often have trouble with them so if its possible to solve this without using any that would be great.

## Creating Rows Of Years

May 11, 2006

I'm wondering how you can quickly create a row of labels holding Year 1, Year 2, Year 3, etc. I used to know how but I can't seem to remember anymore and can't find how to anywhere.
