Calculate Business Hour Downtime Excluding Weekends
Feb 15, 2008
I am trying to calculate downtime for a Service Level Agreement.
The data that I have is the start date/time and the resolved date/time for an incident.
The data are in the format - 1/1/2008 03:32 AM. The incidents may occur at any time but downtime is calculated only business hours and excludes weekends. I may be required to exclude holidays but that is not a hard requirement right now. What I must be able to specify are the working hours.
As example(s)
- if an incident is generated on 1/2/2008 4:00 PM and resolved at 1/3/2008 11:00 AM then the downtime is 4 hours.
- if an incident is generated on 1/12/2008 4:00 PM (which is a Sat) and resolved at 1/14/2008 11:00 AM (which is Monday) then the downtime is 3 hours.
The above assumes working hours are 8:00 AM through 5:00 PM.
I have tried using the NETWORKDAYS and WORKDAY functions with little success.

I wanted to calculate the difference between dates, excluding the weekends. After much thought i used =NETWORKDAYS(A1,B1)+IF(NETWORKDAYS(A1,A1)+ NETWORKDAYS(B1,B1)=2,-SIGN(NETWORKDAYS(A1,B1)),0) that seemed to be working fine. However, I had a problem today with this formula when my start day was saturday (24/05/08) and the last day was monday (26/05/08). What i want is that when i take the difference between these two days, i should get zero as answer as we are not including the weekends in calculation so the start date should ideally be the first weekday which is Monday. However, the formula is giving me 1 as an answer.
This formula works fine if i select 27/05/08 as last date in which case i get 2 as an answer which is right. In gist, what i am looking for is a formula which will give me the difference between two dates and exclude the weekends from the calculation. The last date can't be a weekend, but the start date can. Hence, whenever the start date is a weekend, the formula should take monday as a start day.

I am using the same structure to update another column, under the same sub:
If Target.Column = 5 Then '
Select Case Range("d69").Value
Case "CB1W"
ActiveCell.Value = DateAdd("ww", 1, Now())
Case "CB2W"
ActiveCell.Value = DateAdd("ww", 2, Now())
Case "CB3W"
ActiveCell.Value = DateAdd("d", 21, Now())
Case "CB4W"
ActiveCell.Value = DateAdd("d", 28, Now())
Case "CB5W"
ActiveCell.Value = DateAdd("d", 35, Now())
Case "NI"
ActiveCell.Value = ""
Case Else
ActiveCell.Value = ""
End Select
I would like to apply the code to the whole column but if I change Select Case Range("d69").Value to Select Case Range("d2:1000").Value I get a Type Mismatch Error (13) - (on Case "CB1W" ) - column d cells are data validation drop down boxes that get their value form a named ranged :Lead_Status. The column is also formatted as Text. (I applied the code to d69 because I have data already in the other cells which I don't want altered till I have the code working)
I would also greatly appreciate your advice on how to incorporate the WEEKDAY function to exclude weekends for the DateAdd function.

I have a worksheet where I capture the date and time of each new entry in column A.
In the next column, it's counting up the number of hours since that entry was made. However, it's including Saturdays and Sundays in this count and I was wondering if there's a formula to calculate the number of hours excluding Saturdays and Sundays? I know that network days would count the number of working days from one date to the next, but really need hours. Is this possible?

How should I calculate working hours between two dates? Say if start at 9/25/2009 7:26:13 PM and finish at 10/20/2009 9:46:13 AM, the function should return 245:20:00 because the working hours are from 8am to 11 PM (8 - 23), and there are weekends between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates.

I would like to find out if a job took more than 24 hour cycle time (eg. 6:00 am to 5:59:59 AM next day). data:
A1 = received date & time (format "m/d/yyyy h:mm")
B1 = completed date & time (format "m/d/yyyy h:mm")
my formula is '=if(B1-A1>"24:00"+0,"Yes","No"). The problem with the formula is that it doesnt exclude weekends nor public holidays. I couldnt formulate a solution using networkdays function......

What calculation would I enter in a results cell if I wanted to find the delta between 2 times in date format that repersent just the business hours of 8am-5pm, therefore excluding after hours and weekends.
eg.
Date 1 Date 2 Result Time
23/07/07 8:00 24/07/07 14:55 15:55
So far I can't get the caluclation that will compensate for the after hours and week ends.

I am generating a spreadsheet that focuses on a target opening date. There is about 12 other headings along the top all stating the different phases of construction, permitting, etc. I need to exclude weekends and holidays from most of these columns, and only exclude holidays from about 2 of the columns. I think I am to use the formula for NETWORKDAYS, but not sure how or where to incorporate it.

I'm trying to have a two week rolling dates, starting on the Monday and continuing until the following Friday, this is fine if static but when the start date is then Tuesday, Wednesday etc the week then includes either the Saturday or Sunday.
From using =TODAY(), how do I populate the next ten working days without including the weekends?

I currently have a formula like this:
e87-7+choose(weekday(e87-7),1,0,0,0,0,0,2
this formula is used because I was adding or subtracting a certain number of days from one date to figure out when a certain event would occur next. When the date fell on a weekend, I wanted to make sure that it rolled over to the next closest weekday.
HOWEVER, what I also want this formula to do is exclude weekends in the counting of the days. So basically, I want to exclude weekends completely from my formula.
example, Printing always occurs 4 days after the p.r. meeting. the p.r. meeting is in e87. so e87 + 4 = the printing date. but I dont want those 4 days to include weekends in the count AND I dont want the final date to fall on a weekend either.

I have a holiday and sickness chart for all of the guys in my maintenance department for the whole of next year (2014). The holidays part works fine. The sickness is split into two areas; the number of occurrences of sickness and the total number of days sick. To make the formula work for the number of occurrences it is necessary to enter sick in both Sat and Sun if the sickness spans the weekend. But we do not work the weekend and so I do not want to count those two days. The formula needs to cover the entire year (cells BL5:ZL5). The calculation that I am currently using is =COUNTIF(BL5:ZL5,"Sick")/2 (divided by two as we log a.m. and p.m. and the answer is in days). In the example attached, it would be 1 occurrence of sickness and 3 days sick, not 4 as shown.
For completeness, the formula that I am using for the occurrences is =SUMPRODUCT((BL5:ZL5="Sick")*(BL5:ZL5<>BK5:ZK5))

I have a report that starts with a desired date and generates dates backwards on when certain releases should come out. I would like the code to see the date, move it back a week, check to make sure it's not a weekend or holiday, then post it in the cell below. If it does happen to land on a weekend, it should then be the Friday before the weekend. If it is a holiday, it should be the date before the holiday, as long as it is not a Sunday (or another holiday).
Attached is the workbook that I'm using. I'm starting with the desired date 'B7' and using the Holidays in a seperate worksheet. I know that in the current example, nothing will land on the weekend, unless the holiday pushes it back to one.

I am trying to set up a sick leave list which will work out the cumulative total for the last 12 months (from last day of last sick entry). The problem I have, as the is is added to, I need a function/formula to work out 12 months from last date and then add up the no. of sick days from then to the last date. Hope this is clear. The next problem is I need it to work out total days and then without weekends. Below is the chart I have to work out.
Column 1 Start date of sickness
column 2 End date
Column 3 the number of days sick in period (column 2 less column 1 in days)
column 4 the number of days sick in period above excluding week ends (column
2 less column 1, less weekends in days)
column 5 total sick days in last 12 months from date in column 2 going back
a year including weekends
column 6 total sick days in last 12 months from date in column 2 going back
a year excluding weekends
What function or formulas can I use to calculate column 3,4,5 & 6. I am a not very experienecd in Excel

I've been reading up on Excel's date and time functions and can't really figure out the best way of doing this.
I have a total amount of time that a machine should take to finish a task. I'd like to enter a date and time into a cell (Start Date) and have another cell return the date and time that the machine should be done with the task excluding weekends, and holidays (End Date). This would be based on a certain number of "working hours" (hours in the workday minus break periods) that would be calculated in another cell.

I am attempting to create a formula that will select a value from a lookup table where that value is related to a specific date BUT that date, derived from an input date (any day within a selected month) must always be the first BUSINESS day of that month.
For example:
I have a workbook with two worksheets in it.
The first worksheet is the input page.
On that page I want to have a list of dates which display the FIRST BUSINESS DAY of a month - e.g.
Cell A1 - Date entered as 19/9/12 and displayed as 19-Sep-12
Cell B1 - NEEDS THE REQUIRED FORMUAL TO CALCULATE THE FIRST BUSINESS DAY OF THIS MONTH (SEP)
(in this example, this should be 3) and displayed as 03-Sep-12
Cell C1 - Will display the value from the lookup table on worksheet 2 (see below) related to the date in B1
The second worksheet is a lookup table containing a sequential list of dates from 28-Jan-69 through to present (19-Sep-12) in Column A.
The adjacent column B contains the related value to that date (the value being a foreign exchange rate) - e.g.
Daily
Date
USD
29 June 2012
1.0191
1 August 2012
1.0507
[Code] ........
Worksheet 1, Cell C1 should display the value of 1.0266

I have created a table for a business to monitor all income and expenses within a financial year of that business. This table contains raw data for example, date, income/expense, wholesale amount, retail amount etc. So when the business makes a sale for example I enter in the date of the sale, type of sale, wholesale and retail amounts etc, and i do this for every sale I make.
What i need to do is figure out a way to calculate the average monthly and weekly income to date so as the financial year continues and i make more sales i will continue to enter more data into this table and it will automatically adjust to the new weekly or monthly average income. This way i always have an actual and live average for every cent the business has made as the year progresses and i can use this to budget for the business. I would also like to know what the income is for the current week or month. that way i can say for example on average the business makes $4000 a week and in this week it has made say $5000.

I've being trying t calculate an excel formula to work out a order turnaround time based on opening hours.
Example: The store is open from 8 am to 6pm monday to friday, I need to get a formula to work out how long it took from the time the order was logged until it was completed, during the course of the working day - this works fine but if the order was received on 06/12/07 at 5:20 pm then was finally completed by 7/12/07 at 11:55 the next day I need to figure out how to take into consideration of non working hours during that time. (time from 6pm to 8 am next day
example 2 - if order was sent on the 06/12/07 at 01:30pm and completed at 06/12/07 4:30 then I know its taken 3 hours to complete
example 3 - if the order was sent on the 06/12/07 at 5pm and completed next day at 07/12/07 at 10am - then I know it took 3 hours to complete

to calculate how long a ticket is open in our system before being resolved. I don't want to count weekends, and if the ticket is 'suspended', I don't want to count that either. There is also the factor that the ticket 'un-suspend' date may be later than the ticket 'closed' date. Which is the bit that's throwing me.
So, I have the following fields
Ticket Open, Ticket Closed, Ticket Suspended Date, Ticket Unsuspended Date
A sample ticket might be (using above fields)
02/11/09 09/11/09 04/11/09 30/11/09
That 'should' equal two days (16 hours) as the Unsuspend date falls after the close date so it was suspended from the 4th until closure.
Now I want to know, in hours (8 hour day) how long that ticket took to resolve (i.e close), remembering you can't count the time it was suspended, or any time that fell over a weekend. Also not all tickets are suspended.

I want to calculate a date that is 28 days in the future. I don't want to exclude any days - However - if the end date falls on a weekend or holiday, I would like to push it out to the next business day.
I currently have the weekends covered, but am stumped on the holidays.
(For weekends, I am using the WEEKDAY function on a hidden sheet, and then the following 3 IF statements:
IF today + 28 = Mon.-Fri., then give me today + 28.
IF today + 28 = Sat., then give me today + 30.
IF today + 28=Sun., then give me today + 29.
I have tried adding an additional IF statement to address a specific holiday - namely, President's Day on 2/18/08, which is a Monday - but it won't add the extra day, because I think my initial IF statement re: Monday being today + 28 is overriding it.
