Calculating Numbers Of Specific Dates Within A List Of Ranges

Aug 30, 2007

One of the spreadsheets we have here keeps track of reservations booked in the following way.

FG
101/05/200801/08/2008
201/06/200801/09/2008
301/06/200801/07/2008
401/06/200801/06/2008

The date in F is the check in date and the date in Column G is the check out date.

There is another spreadsheet in the same workbook that counts the dates that these people are checked in.

For example:
AB
1
2JanuaryRooms Occupied
310
420
530
640
751
863
972
1081
119
1210
1311
1412

As you can see column B7 has one room because of the fact that the reservation check in of F1 started on the Fifth of January

B8 is Three because reservations 1-3 are checked in on the sixth of January

B9 is 2 because reservations 1-2 are checked in on the seventh of January

B10 is 1 because reservation 2 is checked in on the eighth of January

Please note that F4:G4 does not count on this worksheet due to the fact that they checked out on the same day as check in.

I would love any help you could give on this confusing subject.

Calculating Dates And Numbers

Apr 3, 2007

I am starting a project that will involve finding how old people are using the difference of two years. Cell A1 will contain the function that automatically obtains the current year from the PC clock (or a manual input). Cells B1...B6 will contain text (names). Cells C1...C6 will contain the month of their birth. Cell D1...D6 will contain the day of their birth. And cells E1...E6 will contain the year of their birth. Cells F1...F6 will have the formula to calculate the difference between A1 and its respective cell column E.

The only functions I know are =(TODAY) which does not give me just the year. Also, I do not know how I would be able to do the calculation [e.i., =(TODAY) - 1988].

Indicator Variables And Calculating Differences Between Numbers In A List

Jun 8, 2009

I got three columns. The left one is the day number. The middle column is for indicator variables 1 or 0. This is suppose to be chosen by the solver function. I want the third column to show the DIFFERENCE between the "chosen" days. This can be better explained through an example:.......

(extra information: the indicator values are chosen by solver based on several criteria not stated here, but this particular part of the sheet is suppose to refrain the chosen days to have differences between them larger or smaller than a given value.

VBA Calculating Max / Min Within Multiple Selected Ranges

Dec 25, 2013

I have a problem with using VBA to calculate max/min within multiple selected ranges.

Here is the file: [URL].... I've also attached it below the post.

Column A to D contain the raw data, column G to L contain the trading data. Each trade is marked with "tick" which consists one buy/sell and one close. The entry and close date&time are also included. Then how to match each entry and close date&time from right to left and therefore to look up max/min value within entry and close time from the raw data in the left columns? Respectively, I would like to calculate the min(low) for a buy/close tick and max(high) for a sell/close tick.

The challenges for me:

1.How to match, or reference from the right to left. I knew that "vlookup" could only match one certain value. (correct me if I didn't know enough about "vlookup")
2.The date&time in the left are time intervals while those in the right are time points. How to refer and locate them?
3.In the right side, length of intervals that each tick marked (i.e.from buy to close) are not the same, so should I use a array to contain the length, and then calculate max/min within each? When the data amount get larger, it is not possible to manually use "min" function.

Calculating Time Overlaps With Multiple Ranges?

Jun 28, 2013

how to calculate time overlaps between two ranges using a MIN/MAX formula. Now I need to do the same, but for three (or more) ranges. I have searched and searched, but I can't find a solution. I've attached a sample spreadsheet.

In the example, John is working three jobs, job one from 8AM-4PM, job two from 12PM-2PM and job three from 9AM-11AM. There is a total of 4 hours of overlap, 2 hours from job two and 2 hours from job three. How can I get Excel to calculate that for me?

Calculating Days In A Month Between 2 Date Ranges

Mar 14, 2013

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].....

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.

Calculating Time Between Two Dates?

May 15, 2012

I need to calculate an SLA.

I have 1 column called 'Date/Time Requested' containing the time and the date together, as in:

dd/mm/yy hh:00

I also have a second column called 'Date/Time Completed' containing the date and time in the same format as above.

I need a macro that compares the two and works out the following:

< 48 hours = "Within SLA"
> 48 hours = "Outside SLA"

Calculating Dates From Text

Mar 31, 2009

I have two columns. The first column contains cells with multiple date values in text format (YYYY/MM/DD) in each cell. The other I was planning to be Calculated cells that I thought would compare the string of text (possibly converted to numbers) and determine which is the next in sequence after today's date. As there may be numbers in the past I cannot just use the first item.

The cell of text looks like this:2009-03-27 00:00:00
2009-04-10 00:00:00
2009-04-29 00:00:00
2009-05-13 00:00:00
2009-05-27 00:00:00

The calculated cell (based on today's date) should output:2009-04-10 00:00:00
Problem: I've been unable to figure out a calculation that will accomplish this. The idea I had was to examine the text in pieces and compare them numerically to "today" (as a number instead of a date).

I'm not very adept with Excel functions yet. I've started with this: "=(MID(A2,2,10))" but all it does is return the first item. I also tried using a Replace function to get rid of the dashes and also one that would return the dates as a decimal. But while I can get the numbers to change format, I don't know how to do the compare...

Excel 2003 :: Calculating Number Of Overlapping Days With Several Date Ranges And Conditions

Jan 6, 2014

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))

Calculating Working Hours Without Using Dates

Mar 18, 2014

I'm trying to calculate shift working hours without using dates.

The scenario is

Cell A1 = Start Time
Cell A2 = Start Time
Cell A3 = Break Time

Basically I want the output to calculate hours worked between:-

0000 and 0600 as a total in cell A4
0600 and 1800 as a total in cell A5
1800 and 0000 as a total in cell A6

Then if the value of A5 is greater than A3, subtract A3, but if the value of A5 is less than the value of A3, A5 should be zero and the remainder of the value of A3 subtracted from A4 (or A6) depending which has a value.

Calculating Dates Until 16 Days From Date

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.

Calculating Due Dates Based On Certain Criteria?

Oct 26, 2012

I have a column CF which has to calculate the due date based on start date in column X and end date in column Y.

This is achievable however; I have dropdown columns in CE which has below option.

Below is the requirement.

If user select "Should Pay" from drop down in column CE, then in column CF the due date has to be Start date + 7 days
If user selects "Not to Pay" from drop down in column CE, then in column CF the due date has to be N/A or Blank
If user selects "Has Time to Pay" from drop down in column CE, then in column CF the due date has to be Start date + 9 days
If user selects "Misc" from drop down in column CE, then in column CF the due date has to be (End date - Start Date)/8+7

if this can be attainable either via formula or VBA.

Calculating Working Hours Between Two Dates

Jul 25, 2002

How should I calculate working hours between two dates? Say if start at 26 july at 15:00 and finish at 29 july at 10:00, the function should return 4 hours because the working hours are from 8am to 5pm (8 - 17), and there is a weekend between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates. And also, if have to add say 8 hours to a date, how should I calculate the result? Also this function should aware of the working hours and holidays, so it should ignore those times.
