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.

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.)

Inmates can apply for pre-release when they have half their minimum sentence served. For example 2 years 6 months. They would have to serve 1 year 3 months.

I use this formula

=DATE(YEAR(A1)-A5,MONTH(A1)-B5,DAY(A1)-B6)

Where A1 is half the years, B5 is half the months, and B6 is half the days. The problem is when an inmate is sentenced to a minimum of 3 years and 3 months. The latter formula will not calculate 1.5 years or 1.5 months. It rounds up. What I would like to do is covert the 1.5 years to months and the 1.5 months to days.

...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...

Is it possible to do the following with a formula in Excel...

I have a list of users with the dates they first logged into a system and the date they last logged in. I'm trying to group them together into segments so I can analyse them using a Pivot table and chart to see how often different groups are using the system, e.g. New customers in December, November, October, etc.

The trouble I am having is trying to convert the different human-readable text strings into a consistent number of weeks from today's date, e.g.

USER FIRST LOGGED IN LAST LOGGED IN user 1 2 years 20 weeks 54 sec ago user 2 44 min 7 sec 1 min 37 sec ago user 3 49 weeks 2 days 17 min 3 sec ago user 4 5 weeks 2 days 33 min 32 sec ago user 5 38 min 9 sec 38 min 9 sec ago user 6 5 weeks 3 days 1 hour 7 min ago user 7 2 hours 17 min 2 hours 11 min ago user 8 45 seconds ago 45 seconds ago

Is there a formula I can use to convert these human readble text strings into a number of weeks elapsed since today's date?

I want to compress my months into seasons. To make things easy I'm going to make winter, jan feb and march etc. i have a column with the months and next to it i have numbers. i need to add the numbers into one season. also i need the months in the left to be differentiated by year so fall 2006 is different from fall 2007

I have a spread sheet I have set up to calculate sales results, I have a column for each week in the quarter with the date at the top and a different page for each individual. I want to be able to enter a number to show how many weeks we have had and the spreadsheet to give me a cumulitive amount for the cells up to that date.

For example if I was to enter 1 in a cell A1 I would want the sum t work out just C3 for example.

If I enter 3 in A1 I would want the sum to be C3+C4+C5 wich is the three cells.

If I enter 6 in A1 it would be C3+C4+C5+C6+C7+C8 etc.

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.

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.

I came up with a formula that i thought should work but apparently not so could someone be kind enough to post a formula that will take the date in one cell and place it in another but showing 6 months later.

I have a excel file which deals with accounting systems. It has the Loan date in Cell B6 and Number of dues in cell B7. I need the column from B11 : B34 to be filled with due dates for every month. Suppose if the loan date is 12/05/2013 and number of dues is 10 then in B11 I should get 12/06/2013 , B12 it should be 12/07/2013 and B13 should be 12/08/2013 and so on based on the number of dues.

In Column A, I have the dates listed as such. Common point is that, they are all 1st day of the month. In Column B, I have Quarters as such.... (Please see below)

Can I put a formula together, to round up how many months left in that particular quarter ? example

See attached. (I added in some arrows for the first month so it is easier to follow the logic)

I am working with monthly revenues. Revenues are earned in a specific month but only a % is received in that month and over the next 4 months. I need a formula that will spread these revenues earned in 1 month over the next 4 months.

Currently, I have a complex Index/Match formula which works until September. September, October, November, and December do not work correctly because once the months roll over from month 12 (December) back down to month 1 (January), my formula cannot recognize the range.

Essentially, I need the formula to return the correct amount that is being paid, even across different years.

I don't know if my formula can be modified or a new formula would be more efficient.

I need is a formula that averages totals from different months out of the year. I already have a yearly average. That was easy. But what I need is a 3 & 6 month average.

I also need it to be most current, so when I am in September, it will take the 3 previous months and average them and same with the 6 month. Then when I move into October, it would take its 3 previous months, i.e. - July,August, September.

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"

I have come accross this calendar online and it suits my requirements, however, the month s currently static and the year is dynamically controlled by a spin button.

The formulas in the relevent days are as follows

Day 1 =IF(AND(YEAR(JanOffset+1)=calendarYear,MONTH(JanOffset+1)=1),JanOffset+1,"") Day 2 =IF(AND(YEAR(JanOffset+2)=calendarYear,MONTH(JanOffset+2)=1),JanOffset+2,"")

and so on, I need the formula and the spin button the also change the month as well as the year.

I have a spreadsheet that each month, we populate a new row of data. The rows are already set up in the spreadsheet, but we just populate the new row.

We are calculating a rolling 12 month total. Each month, we have to modify the formula below to pick up the last 12 months.

For example, next month we will populate data into cell M91, then we need to manually modify our formula to read M80:M91. Wondering if there is a way to have the formula below to look at a range, such as M100:M1, and count the last 12 months? This would eliminate us having to change this each month on several spreadsheets.

In Summary: I would like to replace the M79:M90 to count the last 12 months instead of changing the formula each month.

Here is the formula: =(FVSCHEDULE(1,M79:M90/100)-1)*100

I know I will earn $5,000 of monthly revenue from a client. $5,000 is represented in a monthly revenue cell. I have 12 columns showing the 12 months of the year. There is an additional cell showing the customers implementation date.

If a company's implementation date is on or after the 15th of the month (example: 3/28/2014) then the next month (April 2014) is skipped and the $5,000 is returned to columns May through December. All months prior to May return $0.00. If the implementation date is before the 15th day of the month (example: 3/13/2014) then the next month (April 2014) and all months after will return $5,000. All months including March and prior must return $0.00. If the implementation date is unknown then 12/31/2099 would be in the implementation date cell and $0.00 is returned for all 12 months.

Essentially, if the implementation date is prior to the 15th of the month the revenue will show as of the following month. If the implementation date is on or after the 15th of the month the revenue skips the following month and will show the month after.

I need to figure out a formula for cell F17 that will calculate a percentage change only for the months that have data in 2009. The way it is set up right now I have to go in every month and change the cell reference of the formula to include the latest data. Since the 2008 data is totally populated the formula gets messed up if I include the months of 2009 that have not yet occurred.
