# Date Formula: Add A Month To A Date

Dec 30, 2008

i use dates a LOT in my job however if i want to add a month to a date the best i came up with is the following:

BTW all dates are USA standard (m/d/y)

A1 = 12/1/2008
Lets say i want to add 3 months but the day NEEDS to be 1 because of all of my array sumif's are based off of month 12/08, 2/09 etc, and in excel 12/08 actually translates to 12/1/08. So here is the formula I have been using for the last 4 years....

=date(year(a1),month(a1)+3,day(1)

that seems a bit "Clunky" to me anyone have a better idea?

do not tell me "=a1+30" or "31" because that does not work universally.

## IF Date Formula: IF Formula, That States If A Date Is More Than A Month After The Date In The Cell Then It Is Timely

Jun 2, 2006

I need an IF formula, that states if a date is more than a month after the date in the cell then it is timely and if it isn't then it is not timely. For example the date in A1 is 12/11/05, if the cell is A2 is 13/12/05 (or any date after that) then A3 should read Not Timely, if A2 is 12/12/05 (or any date before that, including a date before the date in A1) then A3 should read Timely. Is there any way to do this?? At the moment I am having to go through manually and put in either Timely or Not Timely.

## Date Range Formula: Beginning Of Month To End Of Month (which Is In The Current Row)

Mar 20, 2009

I have log data in two columns:
Column A: Date/time (at 30 minute intervals)
Column B: Numeric data

On the last row of each month, I�m trying to perform a SumProduct on the two columns and display that result in column C.

The end of the range is determined by the month in the current row.

I�m having difficulty finding the beginning of the range, though. I need to account for both the normal dynamic calendar days & the fact that I may get data starting mid-day and mid-month.

I have this formula, but I�m not sure how to make the first array dynamic or if this is even correct approach.

Manual
=IF(OR(MONTH(A1009)=A4)*(A\$4:A\$65536

## Date Month And Sum Formula

Jan 21, 2010

In the Total column, I would like to determine what the total would be as from the start date till the current date

Columns "C:I" has the dates and the Monthly applicable rates associated.

(in this example, they are annual dates, but it may be that rates change in between a year as well)

In the first set of details (Mr A), the start date is 01/10/2005

Since Mr A only begins 01/10/2005, the rates from 01/07/2004 - 30/06/2005 (\$9) would not apply.

However the rates from 01/07/2005 - 30/06/2006 (\$8) would be applicable for Mr A for the period 01/10/2005 - 30/06/2006 (ie.9 months) ....

## Month End Date Formula

Apr 10, 2007

Is there a formula in excel that will automatically populate a field with the prior months end date? For example - If my spreadsheet is opened on March 25, I would like the date in cell A1 to read 2/28/07.

## Formula To Get Date From Month And / Or Week

May 30, 2014

I uploaded an example file.

Now, what I need to accomplish is that the D1 and D3's in sheet 2 need to result in a date next to the correct country (the date (in full) must be the first monday of the correct week). I find it quit difficult to do this because in sheet 2 you have once the country name, but several possible dates. So in sheet 1 there must be a date for every D1 or D3 but under each other.

The second problem is that I need to accomplish to get a "x" in sheet 3 under the correct month where there is an D1 or D3 in sheet 2 (week).

So I need to go from a week to a month and this can be for one country 1, 2, 3 or even more months (it depends from the D1 and D3's in sheet 2).

## Formula For Month End Date That Changes Each Year

Jun 5, 2014

I have a sheet where the columns have the month end date for each date, ex January 31,2014 February 28, 2014, March 31, 2014 etc. These dates are used in another formula to compare to the current date and if the current date is past the result is different from when if the date is in the future.

I would like a formula that would update the Month end date when we enter a new year. So for example once we get to January 1 2015 my date would change to January 31,2015, February 28, 2015, March 31, 2015. this would note be dependent on the system date but on the date in another cell.

## Formula For Date Of Last Monday Of The Month

Feb 2, 2004

This formula on the forum has helped me to find the first day I specify of the month of a certain year. (here a monday in august of the year specified in B1)

=DATE(B1;8;8-WEEKDAY(DATE(B1;8;1);3)-IF(WEEKDAY(DATE(B1;8;1);3)=0;7;0))

As I'm not really good at understanding the formula (I get confused with the =0;7;0 bit), even though I can make it work I'd like to know how I can find the a last specific day (mo-su) in a month.

## Date Formula (increase By 950 Per Month Automatically)

## Formula For Month Subtraction From Date Format

Apr 24, 2014

What is the simple formula to be used to subract N months from MM.YYYY format

ex:1
Here N=2, MM=04,YYYY=2014

04.2014 minus 2 month means output should be 02.2014

ex:2
02.2014 minus 2 month means output should be 12.2013

## Formula To Calculate Date End Of Prev Month

Feb 22, 2008

I have a worksheet where the current months date is entered in cell E1 (format dd/mm/yyyy) , using an input box.

I need a formula the will calculate the previous months month end date in cell A6 and the month end prior to the date calculated in A6 in cell A13.

where the dates start with 31 for eg 31/01/2008 , then my formula works, but if it starts with 30, 29 or 28, then obviously it does not work.

I would like a formula that will calculate these previous month end dates correctly.

See example below ....

## Calculate Number Of Days Between Two Date Within A Current Month Including End Date

Apr 2, 2009

I have two columns of dates, leave start and end dates (when people start leave i.e. annual leave). Would need to introduce column(s) to calculate how many days fell within the month including the end date and excludes weekends.

For example, if the staff on leave from 31st March to 6 April, i need to show that the number of leave taken as 1 day in March and 4 days in April.

## VBA - Validate Date Entered In Input Box Is Month Ahead Of Date In Cell

Aug 14, 2012

I have a input box that prompts a user to enter a date of a new month - it has to be the 1st of a new month. I have validation that it is a date that has been entered but then i want to validate the date entered is a month ahead of a date in a cell range on a sheet.

It is a monthly reset so it has to roll on from the previous month.

Here is what i have currently but it isn't working.

Code:

' Get user to input the first day of the new month to populate all dates with
dNewMonth = InputBox(Prompt:="Enter first Day of the new Month. Must be the 1st of the Month e.g. 01/10/2012", _
Title:="Enter Date")
' Validates the entered date is a valid date
If (IsDate(dNewMonth) = False) Then

## How To Calculate Average Of Values Against Selected Date Of Each Month Within Date Range

Jan 2, 2014

I have a table that looks like this (its basically a historical data of a stock exchange):

Date
Index
January 4, 2010

[Code]....

The List continues till the current Date.

I want to calculate Average Index Values of a Date of each month within a Date Range.
Example: Calculate Average Index Values for 3rd of Each month from 1st Feb 2010 to 3rd Jan 2011. Formula should calculate Average of the Index Values for 3rd Feb 2010, 3rd March 2010, 3rd April 2010, 3rd May 2010, 3rd June 2010, 3rd July 2010, 3rd Aug 2010, 3rd Sept 2010, 3rd Oct 2010, 3rd Nov 2010, 3rd Dec 2010, 3rd Jan 2011.

Both the Date and the Date Range is variable. Also, the Index Value for selected Date of one or more month may not be available as that being a holiday. In that case, the formula needs to use the last available Index Value before that Date. e.g. If Index Value for 3rd Oct 2010 is not available, system will use the Index Value of 2nd Oct 2010.

## Multiple Condition If Formula That Will Take Into Consideration Month Only In Date

Mar 25, 2014

formula that will compute contract amounts that are paying out for a given month, depending on what is listed as the contract renew date and how often the contract renews.

Assume the contract date is in C1, contract renew date is in C2, Contract term is a drop down menu in C3 that has two options of text, 6 Months or 12 Months. C4 gives the contract amount. There are then dollar amounts in C5 and C6 that are only taken into consideration if they are \$0.00. In B1 will be the run date or the date I want to pull my info for.

I basically need a formula in C7 that will return the contract amount from C4 taking into account these conditions: If there is a dollar amount in either C5 or C6, return "\$0.00" in C7. But if C5 and C6 are both zero, than: If C3 = "12 Months" and B1 is in the same month as C2 (I don't want it to take into account the year of day of the date), than return the amount listed in C4 in cell C7. Or if C3 = "6 Months", and B1 is in the same month as C2 or if B1 is 6 months ahead of the month listed in C2 (again not taking into account the day or year), than return the amount in C4 in cell C7. So basically if the contract amount in C4 was \$100, and B1 3/1/2014 and the contract renew date is C2 is 9/15/2013, I still want \$100 to appear in C7, even though there is only technically 5 and a half months in between the dates of 9/15/2013 and 3/1/2014. I want it to look at these dates and add six months to the month of September and then look at cell B1 and as long as that date is a date in March, return the contract amount in cell C7. I also want \$100 to appear in C7 if the date in B1 was a September date. In the situation where C3 is set to 12 months, if C2 is a September date than \$100 will only appear in C7 if B1 is also a September date.

And one last thing, I'm going to somewhat withdraw my request that the year shouldn't be taken into account. This is only partially true. It just occurred to me that the \$100 should only appear provided the date in B1 is in the same year or in a subsequent year AFTER the year of the contract renew date in C2. So for instance if, C2 is 9/15/2013 and I put in 03/01/2013 in B1, it should NOT calculate the \$100 in C7 since the contract technically would not have renewed in March of '13 as it didn't exist until Sept of '13.

## Date Transformation Formula - Convert Particular Week To Day And Month

Jul 20, 2012

This might be a simple date transformation formula that I need

Column A has numbers like: 200517, 200530, 200544, 201036, 201043, etc

I'd like to get a formula in Col B in corresponding rows that would show date as dd/mm/yy

I know the numbers above are yyyyww = yyyy is year, and ww is the week of that year.

So the formula would have to convert that particular week to the day and month. I understand that are 7 days in a week, but if the formula would reflect Monday of that week, it would suffice.

## Excel 2003 :: Getting Formula Which Will Return Each Date Of Month

## Picking Out Month From Full Date Directly Within Formula?

Apr 7, 2014

A spreadsheet im currently working on has the following formula

=SUMPRODUCT(--('Data Entry'!G2:G6000="AAAA"),--('Data Entry'!L2:L6000="Jun 14"),--('Data Entry'!M2:M6000))

It works fine, apart from the bolded text. In the Data Entry worksheet, column L has dates in the format dd/mm/yyyy. I'd like to get any date from June to be included without manually changing every date in June to Jun 14.

I think theres 3 ways of doing this, any of which would be great. Heres what I think. Where "Jun 14" is searching for exact text, I thought maybe I could change it to MONTH=6 or something to pick out June direct from a dd/mm/yyyy format. I couldnt get this to work. Know of anything I could replace "Jun 14" with?I tried to change the format of the entire column L in 'Data Entry' to a 3 letter month and 2 letter year. how to change the cell date format to fit this?Or if I changed the format of the dates to "01 June 2014" could I change my formula to try and just pick out the specific text "June" ignoring the day and year?

I know there must be a way how, but I can't seem to get it right.

The other option I thought of was to create a new column in the Data Entry sheet using the formula =MONTH(A1), then changing the formula to search for "1", "2", "3" etc for each month. I didn't do this as for the purpose of this the exact date is NOT important, only the Month is.

## Weekday/workday Date 1 Month After The Last Contact Date

Sep 20, 2009

I have a list of clients that have specific requests waiting to be actioned, with a number of columns relating to client details and the status of the request across the top of the sheet. One of the columns (D) is "Last Contact Date", where I enter in the date that I last followed up with the client or made contact regarding their request. In the next column (E), I want the weekday/workday date 1 month after the Last Contact Date.

I can use "=D2+DAY(30)" to give me the date 30 days later, or "=DATE(YEAR(D2),MONTH(D2)+1,DAY(D2))" to get one month later, however what I want is the nearest WORKDAY after this date.

So, if the date is on a weekend, I need the Monday date instead.

## Count Date Cells Where Date Is Previous Month

Oct 25, 2006

I have a spreadsheet which I use to track when a work request is recieved, when we confirm the request and when we action the request. I have been trying to write some code to count the amount of requests, receipts and actions we have processed in the last month.

My first column shows who the request is from
The second shows date recieved

The fourth shows the date actioned.

## Formula To Have Excel Select Date Of Month Based On Certain Criteria?

Feb 24, 2014

I am looking for a formula that will select a date in the month based on certain criteria. Found the choose function but not sure if I can really get that to work. I basically have a list of clients, with zip codes, restricted days of the week - and would like the system to group them by zip code and select the best day of the month to schedule an inspection but not pick he restricted day. The goal being have zip codes scheduled together - but on a day other than garbage day. Is this even doable?

## Formula To Count Number Of Days In Date Range - Split Per Month

Jan 23, 2012

I have a large spreadsheet which holds lots of data with date ranges that i need to performs different actions to. Any way to identify the number of days, per calender month, that falls in a date range.

sample data...

Start Date
End Date
Old Value
New Value

08/03/2010
18/06/2010
16758.2
16758.1

[Code] .......

I need to break down the total number of days per month

Jan
Feb
Mar
Apr
May
Jun
Jul
Aug
Sep
Oct
Nov
Dec

24
30
31
18

[Code] ......

As you can see this also laps into a new year, which poses my next problem, ill probably just add more columns on to the end of the table for that though...

I will later apply different calculations to these cells but in short need to get a calculation for the number of days per month first.

(in short spreading the new value out accross the year then multiplying it by the days... i also need to apply a further daily volume cal to it).

## Check Whether Date Is A Month After Previous Date?

## Finding Current Month Total Sales Using Current Month To Date Sales In Formula / Macro?

Aug 20, 2013

Basically, I'm doing a recorded macro for work where I take an export and manipulate the data to show differences between sales from last year and this year. Also comparing this months projected sales to avg of last 6 months and also against last years this month.

The problem I'm running into is in automating the this month sales for mid-month exports. I can do it individually but I can't find a formula that will do it. Data is in one cell per month, so ex. 130 sales this month so far. I need to have it convert that to projected sales for total month based on what day it currently is.

## Formula That Will Determine The Number Of Days That Fall In A Specific Month Based On A Date Range

Jul 31, 2009

I'm needing a formula that will determine the number of days that fall in a specific month based on a date range. For example, if I have a date range of 10/15/2009 to 01/13/2009, I need the formula to determine the number of days in each month within the range (October has 15 days in the date range; November has 30, December has 31, and January has 13.) I have a large spreadsheet that would be so much easier to manage with such a formula. Currently, my spreadsheet is setup as follows. I need the forumla automatically fill in the number of days under each month.

## 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.
