We have a new series on chandoo.org. – Excel Challenges. From now, every 1-2 months, I will post an interesting Excel Challenge. These are tricky problems for which elegant solutions should be found. To keep the challenges exciting, we will have a small prize for a winner (if more people answer correctly, we pick one randomly)
Excel Challenge #1 – Find Overlaps in Machine Schedule Dates
The inspiration for this challenge came from our forums. This is a question asked by xlfan (I hope that is not a real name 😉 )
My question—
I work in a manufacturing company which makes different sizes of Nuts on many machines. One machine can do only one size of Nuts for a particular period and can be molded for another variant.I manage an excel sheet defining the date ranges of the machine utility for a particular Nut, this allows us to mark our next point for another size.The problem is.. after fixing dates for a process on a machine, I many time loose track of the previous marked dates and issue new dates for the same machine that is usually overlapping and lately found out.
Please help me with a solution ~~~ which does not allow overlapping of dates on a particular machine unless the previous dates allotted be changed.
I use the Table feature of Excel 2007 for this data
Problem Statement:
Download this Excel file. It has an Excel Table, with the following data (snapshot below). You need to write formulas to display Ok or Not Ok in the adjacent column based on the following criteria:
- Display Ok if the scheduling dates for that row do not overlap with remaining scheduling dates for that machine
- Display Not Ok otherwise.

I would apply a filter and use function subtotal, with option 9. This way you can see multiple views based on the filter.
hey Chandoo, the solutions you proposed are very efficient, but if I wanted to be fancy I would do it this way .. the references are as your example workbook.
=SUM(INDIRECT("C"&(MATCH(F5,B5:B95)+4)):INDIRECT("C"&(MATCH(F6,B5:B95)+4)))
I like things simple:
=SUMIF(B5:B95,">="&F5,C5:C95)-SUMIF(B5:B95,">"&F6,C5:C95)
use something like: =SUM(OFFSET(B1,0,0,DATEDIF(A1,D1,"d")))
and have D1 be the date that I want to sum to.
In Excel 2003 (and earlier) I'd use an array formula to calculate either with nested if statements (as shown here) or with AND.
{=SUM(IF(B5:B95>F5,IF(B5:B95<F6,C5:C95,0),0))}
Note that I truly made this for BETWEEN the dates, not including the dates
I turned the data set into a table named Dailies.
I named the two limits StartDate and EndDate.
And used an array formula:
{=SUM((Dailies[Date]>=StartDate)*(Dailies[Date]<=EndDate)*Dailies[Sales])}
If I would still be using the old Excel I would do it as follows:
SUMIF($B$5:$B$95,"<="&H6,$C$5:$C$95)-SUMIF($B$5:$B$95,"<"&H5,$C$5:$C$95)
Works as simple as it is.
Regards
=sum(index(c:c,match(startdate,c:c,1)+1):index(c:c,match(enddate,c:c,1))
=sum(index(c:c,match(startdate,b:b,1)+1):index(c:c,match(enddate,b:b,1))
Great examples and thanks to Chandoo. You have simplified my work.
Hi! great tips I have found in your page, have you seen this

[...] I'm not sure I understand your question fully, but have a look at this: Sum of Values Between 2 Dates [Excel Formulas] | Chandoo.org - Learn Microsoft Excel Online [...]
Thank you! Thank you! Thank you!
=SUMIF(A2:A11;">="&B13;B2:B11)-SUMIF(A2:A11;"<"&A11;B2:B11)
awesome... thank yoo Chandoo!
which is most efficient and fast, if all are efficient ?
Thank you for this formula, I've just spent ages trying to find something to work on my data, I knew it would be possible! Don't care if others think there are easier/other ways to do it, you explained it so I understood it and could apply it to what I was doing so I'm happy!
The above said example is awesome for calculating values between dates,
can you pls let know how to calculate sale values if we have 10 sales boys for
ex: 1,rama
2,krishna
3,ashwin
4,naga
5,suresh
how much rama sale value between 1/jan/2015 to 10/jun/15

Hi
I have a list of people's names in column A, I have a list of dates in column B which records the dates they have been off sick, in column C I have either 1 if it is a full sick day or 0.5 if it is a half day.
What I would like to do is to add up the number of dates a specific person has been off within two dates.
For example, I want to look at my list of names and to find Joe Bloggs (column A), then add up all his sick days (column C). The start date will be in cell E1 and the end date will be in F1.
If this possible using SUMIFS?
List of names are in range A2:A100
List of dates in B2:B100
List of sick days (either 0.5 or 1 in C2:C100
The start date is in cell E2
The end date is in cell F2
Your help would be greatly appreciated.
Yes, with the help of SUMIFS you can have the solution.
Note: you need have an extra col. D2 where you will input Name of the person.
=SUMIFS(C2:C100,A2:A100,D2,C2:C100,">="&E2,C2:C100,"<"&F2)
Col. A Col. B Col. C Col.D Col. E Col. F
Name Date Sales
ABC 28-Jun-11 1 MNO 28-Jun-11 25-Sep-11
XYZ 29-Jun-11 0.5
MNO 30-Jun-11 1
PQR 1-Jul-11 1
Typo ERROR / Correction in formula:

Can you please post the question in the Chandoo.org Forums
http://forum.chandoo.org/
Please attach a file so that a specific answer can be delivered.
Thanks for this - it solved the problem that I was having. However can someone please explain to me why the "" needs to be around >= and <= as well as why we need to add & in order for the formula to work? Thanks in advance!
This formula works perfectly as well. Any ideas?: =SUM(INDEX(C5:C95,MATCH(H5,B5:B95,1)):INDEX(C5:C95,MATCH(H6,B5:B95,1)))
ikkeman had posted the same thing.
I am trying to sum total a range of cells between date ranges ie column n has $ amounts column d has the transaction dates ie 1/3/2015 or 25/3/2015 or 25/4/2015 column b has the text saying drp or distribution - reinv
In another cell I am trying to sum or total (in column n) with the value of a range of different dates (column d) that contain different text (column b) ie cell n48 is 50, n65 is 85, n165 is 36
with the dates ie cell d48 is 1/3/2015, d65 is 25/3/2015 and d165 is 25/4/2015
with different text that says drp or distribution - reinv ie cell b48 is drp, b65 is distribution - reinv, b165 is drp
If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp then the total would be 50. Also if I wanted to sum the amounts between 1/4/2015 to 30/4/2015 with drp the sum total would be 36 If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp and distribution - reinv the sum would be 115
What would the formula be for these different questions
hope you can help, it has been driving me nuts and cant work it out
