Excel 2003 :: Calculating Number Of Overlapping Days With Several Date Ranges?
Jun 25, 2010
I am having difficulty calculating the number of total overlapping days between several date ranges (6 of them to be precise)
I am using Excel 2003 and my data looks like this:
Sent Out (A) - Received (B)
01/06/2010 13:00 - 30/06/2010 13:00
02/06/2010 13:00 - 16/06/2010 13:00
09/06/2010 13:00 - 10/06/2010 13:00
21/06/2010 13:00 - 25/06/2010 9:44
23/06/2010 13:00 - 25/06/2010 10:56
23/06/2010 13:00 - 29/06/2010 13:00
I really can't wrap my head around the idea of calculating overlap (in network days) between six date ranges and was wondering if any of you would have a solution to this problem.

I am having difficulty calculating the number of total overlapping days between several date ranges for each item in another sheet which has unique items
I am using Excel 2003 and my data looks like this:
Sheet-1 Sheet-2
Item - Sent Out (A) - Received (B) Unique Item Number of days excluding overlap days
1234 01/06/2010 - 30/06/2010 1234 -
4321 02/06/2010 - 16/06/2010 4321 -
1234 09/06/2010 - 10/06/2010
4321 21/06/2010 - 25/06/2010
1234 23/06/2010 - 25/06/2010
4321 23/06/2010 - 29/06/2010
I have used the below formula found from the earlier post but need to add a condition calculating the days for each item.
=SUM(IF(MMULT((NETWORKDAYS(ROW(INDIRECT(MIN(INT(A2:A7))&":"&MAX(INT(B2:B7)))),2)<6)
*(ROW(INDIRECT(MIN( INT(A2:A7))&":"&MAX(INT(B2:B7))))>=TRANSPOSE(INT(A2:A7)))
*(ROW(INDIRECT(MIN(INT(A2:A7))&":"&MAX(INT(B2:B7))))<=TRANSPOSE(B2:B7))+0,ROW(A2:A7)^0),1))

I've managed to sort the first half of this issue, in that I can calculate the number of days within a given month which fall inside specified to and from date parameters..
The formula I've used is thus :
Code:
=IF(EOMONTH(A13,0)EOMONTH($I$9,0),0,IF(EOMONTH(A13,0)>$I$9,$I$9-(EOMONTH($I$9,-1)),EOMONTH(A13,0)-(EOMONTH(A13,-1))))))
This examines a date value (A13 in this case) and assess whether any days within that month are between the two date parameters specified in H9 and I9.
H9 = 01/01/2011
I9 = 15/05/2011
Jan-11
31
[Code]....
What I need to do now is specify a second set of date parameters in H10 and I10 and add those into the assessment. The dates will NOT overlap.
So, for example, if I were to set H10 as 01/07/2011 and I10 as 15/07/2011, the results would appear as below
Jan-11
31
Feb-11
28
[Code].....

I need a function to work out what the date will be 45 WORKING days after today(), this function needs to exclude Saturdays, Sundays and any Public Holidays i.e. there could be either 10 or 12 weekend days added into the calculation depending on when today() is plus any additional Public Holidays.
I am using Excel 2003 although it will need to work in Excel 2010 shortly.

I am making process TAT(Turn Around Time) which required following information. In Excel 2007.
1-Count number of days between two dates where working days are (Sun to Thursday). So required to exclude (Friday,Sat + Holidays)
A1-Start Date Mar/01/2014
B1-End Date Mar/31/2014
C1-No Of Days 22
D1-Days between two dates 21
E1 To E10-Holidays
2-Count number of days between two dates where working days are (Sat to Thursday). So required to exclude (Friday + Holidays)
A1-Start Date Mar/01/2014
B1-End Date Mar/31/2014
C1-No Of Days 27
D1-Days between two dates 26
E1 To E10-Holidays
Note : Any weekend (off days) dates listed in holidays should not effect the query.

I'm having trouble defining the time overlaps on continuous days for the varying results of the runs for my simulation.
For the following data set, without counting overlaps there are 18 total spare requirements, but if I take into account their overlaps in their duration there should be a total of 11 per day. For example in row 4 this event overlapped in the same day with the event of row 5 so both had only 2 overlaps as a result (So there is not possible to be 1 as an answer for overlap, there is only from 2 to "n" amount or 0).
But if an event overlaps with more than one in their duration the result would be their maximum overlap during this time frame.
So then I have for each event an Starting date, starting time, duration, ending date and ending duration.And for each day I would need the total amount of overlaps occurred for the duration of each event and from those I would take their maximum amount of overlaps occurred per day. To obtain their real requirement as shown on the file.
The manual procedure I'm using looks like this for the first day: (Graphical representation)
Event 1 occurs from 17:02 to 20:29 and only overlaps with Event 3, so it's 2
Event 2 occurs from 20:38 to 23:38, also only overlaps with Event 3, then its also a 2
For Event 3 in its whole duration only overlapped with Even 1 and Event 2, one at a time so its maximum overlaps where only 2.
And that's what I'm using so far to determine these amounts but since is a simulation, I would end up with several data from each run and this method would be too long. That's why I would need this template to paste data for each run (15 days) and obtain my results faster.

Using Excel 2010.
I am trying to come up with a formula that will return a total average from two columns of dates with criteria. The range will need to cover an entire column as my data is continuously growing and the criteria would have to limit the start date to each month. I have tried
=AVERAGEIFS(DAYS360(A:A,B:B),A:A,">5/1/2012",A:A,"5/1/2012",A:A,"

I want to calculate the end date of my German courses. This is how it works:
A course consists of 60 LU*. The course can occur i. e. three times a week: Monday, Wednesday and Friday. In each day the course lasts 2 LU, which means 6 LU each week. There is no course on Tuesday, Thursday, Saturday, Sunday and on holidays. Therefore this type of course that begins on 18-Nov-2013 will end on 03-Feb-2014.
Another course which occurs Tuesday, Thursday and Saturday, and respectively has 2 LU on Tuesday, 2 LU on Thursday and 3 LU on Saturday and starts on 03-Dec-2013 will end on 06-Feb-2014.
Therefore I want to create a worksheet where I set the start date, choose the days and respectively the LU amount on those days. The end date shall be calculated according to these criteria.
The workday function on excel cannot do this and I do not have any programming skills to work with VBA.
Legend:
*LU = lesson units; 1 LU is 45 minutes
Holidays:
28-Nov-13
29-Nov-13
08-Dec-13
09-Dec-13
25-Dec-13
31-Dec-13
01-Jan-14

I am trying to calculate dates that will happen 16 days from date specified in column A (A23:A200), based off a certain entry in Column B (B23:B200), which is named in cell P5. I can get the date by doing the specified date + 16, e.g. =IF($B$23:$B$200=$P$5,$A23+16,"")
The trouble I am running into is not having the date populate until it has reached 16 days from the dates in column A, show blank if possible until 16 days from date in column A. The dates in column A will always be previous to todays date.

I'm trying to calculate the length of a work order to develop an average and future proposal estimates.
For example:
Job received = A1
In work = B1
Job completed = C1
Total days to complete = D1
I know I can enter in D1 C1-A1 and get the correct result but I want the field to calculate A1-TODAY() until a completion date is entered. This would display the number of days the job has been in work until completed. Once completed use the C1 for calculation.
Sorta like
If(C1=">=0" then (A1-Today()) else C1-A1)
I will then use conditional formatting with block colors to indicate whether it is a completed job or in work job.

It should be deplaying dates of weekly days in Monday, Wednesday and Friday excluding sundays. Or Tuesday, Thursday Saturday excluding Sunday. e.g
Mondays, Wednesdays and Fridays of June
June 1, 2006
June 3, 2006
June 6, 2006
Tuesdays, Thursdays and Saturdays of June
June 2, 2006
June 5, 2006
June 7, 2006
This should be happening after entering any date on the first cell of the List and should accommodate up to 3 months

I have a spreadsheet where I have an intial date of issue of a warrant. Once this warrant has been executed, then a further column is populated with the date. The data I need to work out (Preferably without using macros if possible) is, if there is no execution date the length of time from issue to todays date, but if there is an execution date then length of time from issue to execution. I can do either on their own, but i would like to have only one column showing this info and if possible to update each time the sheet is opened

At the end of each month, my agency collects data about clients served in our programs. One of the many pieces of information they want is the number of "bed days" a client was residing within our programs for the given month.
For example:
Jon Doe entered the program on 7/16/13 and discharged on 8/15/13. I would like to know how to calculate the number of days in July that Mr. Doe was residing in the program. (The date of discharge is not included.)
I recently took over the responsibility of completing reports such as this one at my office. The previous person who completed the monthly reports would count the days by hand for each client, but I know there must be a better way.

I need a formula that will calculate the number of days (ex from 10/1/08-1/1/12) and will differentiate between leap year and a regular year. I am trying to calculate interest between 2 dates and leap year is calculated on a different interest rate. Right now I have it set up so I have to manually type in the leap years in a separate field instead of being able to just you point a to point b.

I am working in Excel 2003. I consider myself a little more experienced than a beginner, but not quite an intermediate. My problem is, I am doing percentage changes comparing the average year-to-date data of 2009 through 2012, and then I am attempting to get the percentage change of the current year-to-date data to the average of the aforementioned years.
I took an average of these numbers, that are pulled from other worksheets. The cells are set as "General".
112241 = 1.833333333 or rounded, 2 divided by 1 (the current year to date total), the result is -45%, which should be -50% decrease. The percent cell is set at percentage.
It appears the cells are not automatically rounding up.

I run a small holiday cottage and I want to use excel to tell me which days of the year I get most enquiries for.
Every time I get an enquiry for a certain period in the cottage, I enter the dates into excel.
I have two columns - Start of holiday and End of holiday.
What I would like to do, is give each day of the year one point if someone enquires for it.
e.g. If someone asked for 3rd january to 5 january, I would give 1 point to the 3rd and 1 point to the 4th of january (but not the 5th as that is the day they would leave!)
At the moment I find it easier to count with pen and paper than use excel for this problem.

Full days into month 7
Formula to sum data in columns B that only looks at dates 01/07-07/7
I will the adjust that formula for a January date that only pulls data for 01/01-01/07

I am using Excel 2003.
I have a column. D3-D7 have numbers in them and I want to add them. I put a formula in D8 to SUM all the Cells From D3-D7. No problems there.
When I insert a row above D8 the range for the SUM is not expanding, and if I do put info in the cell a box comes up asking if I want to update the formula.
Is there a way to insert a new row and have it be included in a range?

I have a spreadsheet, but it came from another file using the detach sheet method. It has therefore taken with it, all the named ranges that are now superfluous.
It seems a bit long-winded to delete these named ranges one by one manually. Would there be an easy to understand script that would delete them all, so I can start with a "clean sheet".
I'm using Excel 2003.

I am trying to get the results of the number of days between today and a future date. I am using ="cell containing futuredate"-today() and it gets me the correct number of days. The problem comes in when I have yet to populate the future dates. I am getting -39991 (numeric value between today and jan 01 01) and because I am also using conditional formatting this is even more of a problem. Is there a way get excel to display nothing if it is a negative number? or to give a specified resut if the number becomes negative such as Expired or something of that nature?

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.
