# Calculate The Average Start Time For A Machine Over A Period?

Mar 6, 2014
I am trying to calculate the average start time for a machine over a period. However the machine start time varies from 10:00 pm to past midnight. I have tried reviewing past posts but cannot seem to find a similar query.

I need to determine a formula which will allow me to calculate a future date based upon a current date with varying time periods.

For example:

I have a bill which is paid on the 15th and last business day of each month. I would like to be able to see the next due date regardless of what day of the week it is.

I have a bill which is paid every other Tuesday. I would like to know the next due date without having to enter +14 for every due date in the future. In other words, it is preferable to be able to open the spreadsheet and automatically see the next due date, not use autofill to repeatedly add +14 to a previous date which would limit the # of future due dates that could be calculated.

I have a bill which is paid on the last business day of each month, not the last Friday of each month. I would need excel to return a value for the last day of the month which = Monday-Friday, regardless of what day of the week it may be as long as it isn't Saturday or Sunday(holiday exclusion would be nice but not required).

I am creating a timesheet using excel 2003 users enter their shift start/finish time and a break start/finish time. Emplyee's can work night shifts (ie across midnight).

There are penalty rates which apply at different times. I need to be able to work out the amount of worked time that fits into a certain time period. eg. 10pm-7.30am, 7.30am-10pm.

I have a solution based on A clever formula from Daniel Maher that will calculate time within a period. But it doesn't work when the shift goes over two days.

I have attached a spreadsheet to help show the problem .......

This may be a bit vague but here goes.

I have to calculate the difference between the start time and end time of a job. The only catch is, how can I avoid calculating "out of hours" time. So, if a job goes from 9am to 9am the next day, I want it to avoid calculating between the hours of 23:30 and 03:30.

Another example is if a job goes from 02:00 to 04:00, I want it to avoid the tim between 02:00 and 03:00.

If there is a difference in days, so the job goes overnight, how do I take that into consideration also.

Is it possible to calculate hours if both the start and end time are in the same cell. Unfortunatly the developers of our scheduling program developed it so when you export the schedule to excel it shows Greg in A1 and 3:00pm-9:00pm in A2. I would like to have excel calculate the 6 hours so I can use it to auto generate another spread sheet I am making.

I have a small project at work where I am being asked to put a simple spread sheet that will calculate a start/stop time - and also include the date. For example:

Start time 5pm, date: 3/13. The spread sheet to auto calculate what the stop time and date will be if a specific amount of hours is to be calculated. For example in this case, 12 hours. From calculating in my head that would be 5am the following day. However, how can I get this in excel to work and therefore all i would have to do is enter the start time and date, + 12 hrs, and excel would calculate the time/date after the additional 12 hrs.

I can calculate total hours when a user enters a start date/time and a finish date/time. The kick is I only want to include hours from 2:00 PM to 12:00 AM (10 hour period). So assuming all the start and end times will be in this range, how can i calculate work hours over multiple days? For example: Start date/time = 2/26/13 2:30 PM and end date/time = 2/28/13 10:30 PM. I want my calculated hours to show 28 hours.

I have a pivot that includes customer data and I need to create an average for each row based on the first populated column for each customer. After one month of units appears for the customer, I need to calculate the average going forward, and if there are blanks after that they should be treated as 0 in the average. Below is an example of my description of the pivot.

Jan Feb Mar Apr

Customer #1 1 1 3

Customer #2 1 3

Customer #3 2 2

So, the average for customer #1 would be calculated from Column B to Column E, and factor column D as a 0 in that calculation. Customer 2's average would start in Column C and go to Column E, and factor column E as a 0 in that calculation. Customer 3's average would start in column D to column E.

I have a set of 7 years daily rainfall data. I need to calculate the daily average of rainfall from this 7 years data set. I don't wanted to calculate it by for example copying and pasting the first day rainfall of each year rainfall to a new sheet and average it for all the days. I need to calculate it all at a time.

I have a protected worksheet. Users wish to be able to track changes in the input cells. The suggested approach for this is to temporarily disable sheet protection and allow them to change the font color, then protect afterwards. What I would like to do is:

i) check whether they are in an input cell

ii) if so, then prompt the user with the 'Font Color' dialog box

iii) apply the font color selected to the input cell

I'm struggling to find the dialog box I need. I can launch the one to change the interior color, no problem (Application.Dialogs(xlDialogPatterns).Show). But that's no use to me, I just want a color palette that specifically relates to the Font Color

I have thousands of timestamps that have a start & end date and time in 2 separate columns. (one named start and one named end...)

I also have numerous set time periods that i'm interested in.. (about a dozen or so)

for example 01/01/2008 - 05/01/2008, 07:30:00 - 10:00:00

What i need is to be able to count the number of times the full time period i am interested (07:30:00 - 10:00:00) in falls in between the thousands of start and end timestamps i have. The time periods must also fall within the date range specifed.

So if my timestamps were

Start: 01/01/2008 06:30:00 & End: 02/01/2008 11:00:00, based on the set time period above, there would be a count of 2

and if my timestamps were

Start: 01/01/2008 07:05:00 & End: 02/01/2008 09:00:00 there would be a count of zero as there is not a full uninterupted timeperiod 07:00:00 - 10:00:00 between these timestamps.

and if my timestamps were:

Start 01/01/2007 07:00:00 & End 02/01/2007 10:00:00 the count would be zer as this is a year early!

I want to return a value based on once off time related data which is captured at 4 time periods throughout a day. I have another set of data which does not line up with this data but I want it to return the value closest earliest value.

Given this data:

27-6-14 3:00 12

27-6-14 7:00 18

27-6-14 11:00 19

If I have a time like 27-6-14 5:00 I want to return a value of 12 (Previous time). How would this be possible?

I have a logbook which already uses a number of SUMIF formulas but have been trying to create one so that totals the number of hours flown in the above mentioned periods. I am attempting to copy the formula and then modify for the relevant column in this case: =SUM(IF(FlightDates<(TODAY()-90), 0, FlightLength))

FlightDates is the named range of the calender date in column A and FlightLength is the named range for total flying in column Z. However even though this forumla works in another situation e.g. tracking number of landings in the last 90 days, it comes up with an error.

I have a worksheet which contains START TIME in column A, then TIME USAGE in column B and END TIME in column C. User enters start time, followed by the number of time usage in minutes, how could i possibly display the end time automatically in this scenario? how do you add the entered time usage to the start time to display the end time? Say if I enter 1:00 AM at start time and 00:15 minutes on time usage, how can 1:15 AM be displayed on the end time automatically?

I need to calculate a pay back period for a certain investment. Excel has options for NPV and IRR but not for the Pay back period. (PBP). I've tried finding a solution using google discussion groups and some books but nothing helped me out. attached you'll find an example of my sheet. I need the PBP to be calculated in e.g. 5,3 years. but when the figures change it should automaticly recalculate the PBP.

I need also to calculate difference between dates(dd-mm-aaaa hh:mm) in workhours ( hh:mm):

The work period is 9-18 with lunch interval 13-14 The startdate and end date could be out of the work hours and i can't include the extra hours. I can have several days (workdays) at the difference, but i should maintain the format hh:mm.

Ex1:

Startdate 05-03-2013 18:34 ( date to calculation should be 05-03-2013 18:00)

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

will be equal to:

Startdate 06-03-2013 8:34 ( date to calculation sould be 06-03-2013 9:00 )

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

Ex2:

Startdate 06-03-2013 12:01

End date 06-03-2013 14:28

Time Difference 01:29

I am trying to provide a tool for department leaders to monitor productivity for order processing in their departments. The variables I have are: Number of orders(variable), number of pickers (variable), start time(variable). Then, I know each order takes 1 picker 4 minutes to pick on average, and there are 45 minutes worth of breaks during the picking process. So after entering the variables I used =(((C3*4)/60)/D3) to come up with the time needed to process the orders. What I can't get to is how to add this number to the start time, factor in break minutes and get to the projected completion time. I have Excel 2003 at work. Clearly I need to take a class!

Finish time: 23:00

Hours worked: 10.50
