## Formula: Use Numbers For Weeks & Months

Nov 20, 2006

It's a formula I'm looking for. The best way to describe it is an example.

I have some numerical data on a sheet from cells A2 to A80. This data represents the amount of days each person has spent on holiday. The data will be shown on a graph, but instead of the graph having "1", "2", "3", "4", along the bottom, I'd like it to have "1 week", "2 weeks", "3 weeks", "1 months", "2 months", "3 months".

I -suspect- the formula will involve the " countif" function (or an equivalent) (eg. if the number is less than or equal to 7, add 1 to the "1 week" box, etc.)

## Formula To Convert Months Into Weeks

Aug 13, 2008

I'm having an issue converting months into weeks. My example is I have people who must provide leaving notice (could be months or weeks). For instance column B details months, and column C details weeks. I'd like to convert months (column B) into weeks in column D, but am not sure of the components of such a formula so I won't list or guess as I'm just not sure.

## 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...

## Conditional Format - Dates Greater Than 18 Months And 24 Months?

## Turning Dates Into Weeks

Jan 14, 2009

"Decision Date". It is a numerical date (ex: 1/5/09 indicating January 5th 2009).

I need to turn that date into the week that it falls into within a particular quarter of a year.
1/5/09 would be Week 2 (it is in the second week of January, and 2nd week of the quarter)
2/3/09 would be week 6 (6th week of the quarter).

And then I need the formula to start over once each quarter restarts... for example, April 1st would be week 1 (1st week of the second quarter).

## Counting Weeks INVOLVED Between 2 Dates

Nov 3, 2008

I've been having problems coming up with a formula that will take a start date and an end date and come up with the number of weeks INVOLVED within this date range (each week being a Sunday through Saturday).

My problems is that the start and end dates could be any day of the week and not necessarily the same day (meaning divisible by 7 doesn't always work). I tried using ROUND((A2-A1)/7,0)+1 where A1 was the start date...and A2 was the end date.

The problem I had was if I picked a Monday as the start date, and went 12 days out (The saturday of week2)...it came up stating 3 weeks were involved - AND if I selected a Friday start date and picked the following monday in week 2 - the result was 1 week involved when 2 different weeks were involved.

## Formula To Calculate Weeks Between Two Dates?

## Grouping Dates Into Weeks Without Using A Pivot Table

Oct 16, 2009

I have a large spreadsheet which lists individual dates over two years and circulation figures next to each date. Sometimes there are two entries for a particular date e.g. 1/10/08 there were 150 readers of magazine A and 200 readers of magazine B. When displaying this on a graph it give a bar for each day, whereas I would like a bar for each week.

Is there a formula to convert the individual dates into weeks and then total the circulation figures for that week?

Column A = Dates
Column B = Circulation Figures

## Count Full Weeks Monday Through Sunday Between 2 Dates

Jul 16, 2014

Count the full weeks (from Monday thru Sunday) between 2 dates.

For example...

Data Range

A
B
C
D
E
F

1
Date
Weekday
------
Start
End
Weeks

2
8/1/2013
Thu

8/1/2013
8/15/2013
1

3
8/2/2013
Fri

[Code] .........

Full Monday thru Sunday weeks = 1

This array formula** entered in F2:

=(MAX(IF(WEEKDAY(ROW(INDIRECT(D2&":"&E2)),2)=7,ROW(INDIRECT(D2&":"&E2))))-MIN(IF(WEEKDAY(ROW(INDIRECT(D2&":"&E2)),2)=1,ROW(INDIRECT(D2&":"&E2))))+1)/7

** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER).

Hold down both the CTRL key and the SHIFT key then hit ENTER.

The logic of the formula is:

The max Sunday date within the date range minus the min Monday date within the date range +1 = total days divided by 7 (days in a full week) = full weeks

## Adding Months To A Date In Excel VBA

Jun 5, 2014

I have a date stored in a variable and I need to add month(s) to that date. For example if I have 10/1/2013 in a variable if I add 1 to that month the result should be 11/1/2013. I am using the following formula but the problem is in the result date format, which shows as 1/31/1990, if I add 2 to the original date, the result is 2/29/1900 which ideally should have been 12/1/2013.

My formula is :
ActiveCell.Value = "=date(year(" & last_date & "),month(" & last_date & ")+" & i & ",min(day(" & last_date & "),day(date(year(" & last_date & "),month(" & last_date & ")+" & i & "+1,0))))"

Any other formula to add months to a given date?

## Adding # Of Months To Calculate A Date

Jul 30, 2007

Is there a way to add # of months to a date and then find out what would be the exact date?

For example if cell A1 = 04/30/07 and Cell B1 = 14 what is the statement that would give me 06/30/08 in Cell C1?

Also, how can I modify the statement if Cell B1 = 14.5 to get 07/15/08?

## OR Or IF Adding: Display A Date 3 Months In Future?

Nov 19, 2009

Three columns.

A - Date last checked
B - Due Date
C - Actual Date checked

Currently column B simply has =A+84 and will display a date 3 months in future.. Great..

However now i want column B to still display the 3 month date - unless there is a date in C, whereby i want B to then display OK. SO what im sort of needing is =A+84 (or if somethings in C then "OK")

## Using Dates And Months In IF Statement?

Aug 10, 2014

I was wondering if this can be done we have a monthly award program so if a date was entered for that drive on this month it would = no if blank =yes but needs to reset each month?

=IF(AND('Driver'!A51:A1000)="",IF('Driver'!A51:A1000>='Driver Bonus'!A3,"YES","NO")) This brings back a #value! error

=IF(AND('Driver'!A51<=A3,'Driver'!A51>=A3),"NO","YES") this works but only for that cell i need to also recognize cells A51:A1000

=IF(MAX(INDIRECT("'"&A8&"'!A51:A1000"))<A3+1,IF(MAX(INDIRECT("'"&A8&"'!A51:A1000"))<>A3,"YES","NO")) this also works but only for 1 day

## Months That Occur Between Two Dates

Jan 13, 2010

I would like a formula (if it is possible) that will list which months occur between two dates;

i.e
Start Date (Cell ref A2) = 01/01/2010 (in the dd/mm/yyy format)
End Date (A3) = 02/05/2010

In cells D2:O2 I have the months Jan-Dec. In cells D3:O3 I would like a "Yes" to appear if the above month occurs between the dates in A2 & A3. In this example would like a "Yes" to appear in cells D3, E3, F3, G3 & H3 but not in the other 'Months' appropriate cells.
