# Calculate Date Difference In Weeks

Sep 21, 2007

On some Military computers the Add-ins were not installed, therefore the WEEKNUM function cannot be used.

The task is to calculate the time interval (in whole weeks) between two dates.
(Every start date is to be calculated as a whole week – same for the End date).

I tried but the most but came up with the incorrect formula in the attached workbook.

## Calculate Date Difference

Apr 20, 2009

I request a help:

A1 = 01-Apr-2009
B1 = 02-Apr-2009

I need to calculate the date difference between two dates and get the result in the number of years and proportion of months ie;

20/09/99 to 01/02/02 is 2.33333333 years. I can use the DATEDIF function to get 2 years 4 months as the result but for the calc I'm doing I need it in the format of 2.33333333. Thinking I just need to tweak the DATEDIF a bit but just can't work it out!

## Conditional Formula: Calculate The Difference In A Date Between Two Dates

Jan 28, 2009

I'm trying to make a formula to calculate the difference in a date between two dates. For exaple, in my business we have a due day for something. So the due date could be Feb 10, we need to know if it was done on time, late, or early. So I've gotten it to display late by doing this: =IF(B2>A2, "Late", (A2-B2)) But then I can't figure out how to incorporate this: =IF(B2=A2, "On Time") or =IF(B2<A2, "Early").

I would like to displaly this all in one cell. So if the due date is Feb 10 and it's turned in Feb 8 it's early, turned in Feb 10 it says on time, turned in Feb 11 it's late. I also tried this but it didn't work: =OR(IF(B2>A2,"Late")*IF(B2=A2,"On Time")*IF(B2<A2,"Early"))

## Formula: Calculate The Weeks Cover Of Current Inventory

Jun 10, 2008

Calculate the weeks cover of current inventory based on a sales forecast. the forecast is in weekly buckets so I was thinking using some form of loop statement within the function which basically starts with the inventory figure then subtracts the forecast week by week until the inventory figure is less than the weekly forecast. I should then be able to divide the inventory by forecast and add back the number of loops to give me the weeks stock figure.

I have done this using if statements but it will only allow me to use 10 statements in the function and I need to do this for a full years worth of forecast.

Does anyone have a suggestion as This problem is becoming quite frustrating.

Here's an example of how the spreadsheet looks

## Formula To Calculate Number Of Work Weeks The Data Has Been Collected?

Dec 27, 2013

I am looking for a simple formula that would look at column A2-A100 and calculate the whole number for the number of the week I am on. So in cell K22, I would like it to add up the A column and spit out a number 4, then on Monday when I add a new record I would like it to automatically update to a 5; indicating the 5th week I have been tracking the data. This number is needed to calculate the average amount in a work week accurately and automatically in cells K20 & K21. New weeks start on Monday and end on Friday. No data will ever have a date of a Saturday or Sunday. I have colored the cells currently to indicate what the number should be. There is 4 alternating colors now. The color coding is just for reference and will not be used going forward. Data will be entered weekly indefinately.

## VB Calendar, If Date Not Within 12 Weeks, Then Msgpop Up

Mar 23, 2009

I can get the calendar control to come up and the value selected on the calendar to show up in a certain cell.

If a user selects a date that is not within a certain 12 week range, I want a message to appear ("date not within 12 week program"), and the user can't select the date.

I am storing nutrition data from a certain date the user chooses and it is a 12 week program from the start date. I want to retrieve info from those 12 weeks but do not want them to be able to select data outside the 12 weeks.

## Calculate Difference In Dates

Jul 27, 2009

I need to calculate the amount of time between two dates, and show it in the number of hours and minutes. My dates are formatted to show the time in Zulu time. So 1406 = 2:06PM.

Here is what I have:

A1 = 6/4/08 1406Z
B1 = 6/5/08 0402Z

For this example, the formula should return a result of 13 hours and 58 minutes. With the result, there is no need to desingate Zulu time with a 'Z'. But I need the result in a format that will allow me to calculate an average for all my data.

## Calculate Difference To Lowest

May 9, 2009

I'm looking for a macro or formula that can calculate the difference to the lowest of col C based on option in colB. See attached. I complete what it should look like in F. Basically, this can be done by sorting the data by colB and using this formual for every group. =C2-MIN(\$C\$2:\$C\$4). This is not ideal because I have many of these to do and you have to adjust the min range for every group. Plus group sizes will vary.

There has to be a better way. Ideally, I would not like to have to sort the data, unless a macro did it for me....

## Trying To Calculate The Difference Between Two Dates

Sep 11, 2008

This is more of a query on date dif

I was trying to calculate the difference between two dates on excel

I had a look through the search message board and searched the web generally where I came across the datedif function

I had found that in order to get the number of years it was

=datedif(startdate,enddate,"Y")

for months same formula"YM" and for days use "MD" in place of "Y" in the original formula

My question is when using datedif to calculate the number of days between two days it initialy gave me the right answer

Number of days between 01/08/2008 - 22/08/2008 - Answer 21 days

Using date dif gave me 21 days but when i did

01/08/2008 - 01/09/2008 - this gave me 0

Am I entering the formula wrong or does datedif simply not pick the difference if the days havent changed even though the month has ?

I then found i could simply minus one from the other , which then had me asking what is the point of date dif

## Calculate Day Difference From 2 Dates

Jul 31, 2008

is anyone aware of a formula/macro that can calculate (in days, hours and minutes) how much time has elapsed between two date and time stamps?

For example [30/07/2008 00:30] and [01/08/2008 01:45], so in days hours and minutes it would look somewhat like this: 02:01:15

## Date Differences In Days, Weeks Or Months

Jan 3, 2008

I've been racking my brain on this one for awhile, and I feel like I'm going the right direction but...

I have a list of dates like:
11/30/2007
10/31/2007
9/30/2007
8/31/2007
7/31/2007
6/30/2007
5/31/2007

or maybe

11/30/2007
11/23/2007
11/16/2007
11/9/2007
11/2/2007
10/26/2007
10/19/2007
10/12/2007
10/5/2007
9/28/2007
9/21/2007
9/14/2007
9/7/2007
8/28/2007

...and I need to determine if the difference between them is daily, weekly, or monthly. There are 79 of these lists, on 79 different sheets so I can't visually peg them as daily, weekly, or monthly.

The way I have been looking at the problem is to calculate the number of months between the last & first dates and see if the resulting answer (+1) matches the number of actual dates, and so on...

## Calculate Difference Between Dates In Two Columns?

Mar 4, 2014

I'm just trying to calculate the difference between dates in two columns and applying conditional formatting based on if it is a positive or negative number. But when there is a null value in either of the date columns I don't want anything returned.

So far I'm either getting a 0 or a FALSE.

Column A = Date 1 Column B = Date 2 Column C = Formula

## Calculate The Average Difference Between Columns

May 4, 2009

I am trying to determine the average reduction amount of appraised property values. I have two columns in my spreadsheet. Column H has appraised value of property. Column I has the accepted value of the property. Sometimes the accepted value is the same as the appraised value, sometimes it is reduced, and sometimes it is rejected.

I want to be able to find the average reduction amount when the accepted value is less than the appraised value and is not rejected.

Column H always shows a numerical value (i.e. \$250,000), but Column I may have a numerical value or show "rejected".
