Calculating Start And Finish Times For A Process

Feb 22, 2010

I have a number of processes that I would like to calculate the finish times of.

For example, Process A may take 18 hours to complete, Process B may take 28 hours to complete and Process C may take 125 hours to complete etc

However these processes only run during certain times, i.e. 9am to 5pm.

Ideally I would like to setup a spreadsheet that when given the start time and process time calculates the (date and) time the process will finish.

I can get it to work on a 24 hour day but I've been tearing my hair out trying to take out the none-working part of the day (the 5pm to 9am).

Number Of Working Hours Between 2 Dates Including Start And Finish Times

Mar 22, 2007

I have 2 dates+ times.

1 the contract start date and time.

2 the contract end date and time.

Can I calculate the number of working hours between these two using a formula?
So if I have a 10 hour working day (08:00-18:00), Mon-Fri and the two Dates/Times can I calculate the number of working hours?

Example
Start 06-Mar-07 10:00
End 14-Mar-07 14:00

This is 2 part days and over a weekend.

Automatically Calculating Shift Start Times

Sep 20, 2013

I'm currently working on a rota for which I would like the worksheet to automatically tell me how many staff members I have beginning their shift before 9am and those finishing after 7pm. I currently have this working via a very crude set of IF statements for each staff member for each day of the week, returning 1 if true and 0 if false. Then I have a sum statement at the bottom of each day. Is there a much tidier and simpler way for me to calculate this?

I've attached the worksheet. A quick note is in Q52.

Calculating Total Time For Individual With Multiple Start / End Times

Feb 12, 2014

I am trying to come up with a formula that calculates total time someone has worked in a day. The scenario is an individual will work at a home and start working with an individual. Their start/end times look like this in a pivot:

Min Start Max Start Min End Max End
Location A+Counselor A 8:56 AM4:01 PM 1:11 PM 7:00 PM
Location A+Counselor B 12:00 AM 8:00 PM 6:00 AM 11:59 PM
Location B:Counselor C 7:00 AM 12:00 PM 2:00 PM 4:00 PM
Location C+Counselor D 8:00 AM 8:00 AM 4:00 PM 4:00 PM

Some people work split shifts while others work a straight shift. The formula I created was this:

=IF(OR(B9=C9,E9=D9,D9=C9),E9-B9,IF(D9>C9,((E9-D9)+(C9-B9)),IF(C9>D9,((D9-B9)+E9-C9),"New Formula Needed")))*24

(I use a pivot table to show max min for start and end times)

This works great except for the individuals that have multiple punches during the same time frame. The one scenario I am having trouble solving for is when someone punches in more than once during their shift displaying. This occurs when a counselor starts a shift working with one person but then adds another person mid shift. An example of this could be:

Location A+Counselor E Min Start Max Start Min End Max End
Consumer 1 1:00 PM 1:00 PM 8:30 PM 8:30 PM Total Time: 7.5
Consumer 2 12:00 PM 12:00 PM 2:35 PM 2:35 Pm Total Time: 2.6

Pivot says that they worked a total of 10.1 because it is grabbing the max and mins and calculating. The actual total time worked is 8.5 hours in reality.

The raw data comes in like so:

Location Counselor Consumer Start Time End Time
A A A 1:00 PM 8:30 PM
A A B 12:00 PM 2:35 PM
A A C 12:00 PM 5:00 PM

Is this solvable with a formula?

Mark The Hours On A Start And Finish Time

Mar 25, 2014

I am working on an excel spreadsheet for work and I have to show a chart that shows the time of day a space is in use. Right now I am having to mark all of these by hand which takes me forever because I have a couple thousand lines of information.

I need to mark the hours in use based off the start and finish time.

For Example:
1) If the start time was 7:00 and the end time was 10:45 then the markers would only mark 7am and 10am
2) If the start time was 7:15 and the end time was 10:00 then the markers would only mark 7am and 9am
3) If the start time was 7:30 and the end time was 10:30 then the markers would only mark 7am and 10am
4) If the start time was 7:45 and the end time was 10:15 then the markers would only mark 8am and 9am

I was given the formula and it works to count the whole hour but now I need the formula tweaked and I don't know how...I need the formula to account for quarterly hours...and I don't know how to fix it.

Attached is an example of the spreadsheet of what I currently have and of what I need. Book1.xlsx

Providing A Start And Finish Cell Into A Range

Jan 23, 2007

I need to create a range of cells in Column A. I know the first cell, A2. The final occupied cell will vary. Once I have the range object I would like to step through and analyse each cell in turn using a For/Each loop.

The code I have so far is:

Public all_structures As Range 'Range required for for/each loop Column
Public last_structure As Range 'Last cell in Column
Public molcell As Range 'Current cell in range

' Establish range of cells in Column A

Set last_structure = Range("A2").End(xlDown)
Set all_structures = Range(Range("A2"), Range(last_structure)) ***

' Loop through each structure in turn
For Each molcell In all_structures

Loop code In here

Next molcell

When I run I get an error message of "Run-time error '1004': Method 'Range' of object '_Global' failed". It does not like the line marked ***.

How To Calculate Work Hours From Only A Start And Finish Date And Time

Feb 28, 2013

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.

Graphs Using Start And End Times

Jul 8, 2014

I have a data which has a start time, end time, Stay Time(End-Start) and # of subjects. I am trying to create a graph, line, bar or histogram which shows how many subjects were there at a specific time. So the horizontal axis would have time from 00:00 to 24:00 and vertical axis would have the total # of subjects or the %.

Start End Subject Stay
01:00 02:00 1 01:00
01:00 01:45 1 00:45
02:00 21:00 1 19:00
03:10 14:10 1 11:00

The data set is huge(27000 rows) and I am using excel to create a graph.

I have tried using line plots and bar charts(stacked) but couldn't. I am not sure if there is an easier way to do it .

Trying to get times worked in hours and mins, from a given start time to a given finished time.

I would like H18 to read 14

H23 and H24 are full 24 hour coverage,
but i get a 0, when using 08:00 - 08:00

as we only deal with a full or half hours, the figures should read whole numbers or half number as in th example above.

Also would like to total all hours worked in H28 to 117 as opposed to the figure given in the attached file.

How Do You Subtract Start/end - Dates/times In Vba?

Dec 8, 2009

How do you subtract start/end - dates/times in vba?

I know how to do it with formulas, but can't grasp it with vba. My range will always change, so I'm trying to avoid formulas (Cutting rows etc...)

I need Col D-Col B (end date-start date) and Col E - Col C (end time - start time)

Would doing the calculation on the userform be the best way, or trying to do the calculation with the ws code?

Calculating Hours With Midnight As A Start Time

Oct 1, 2009

I’m working on a timesheet and I need to separate the hours worked that are before 6 am from all the others. For example if someone works 1:00 am to 8:00 am I need a cell to populated with 5 representing the hours worked before 6 am. The formula below works fine except when the start time is 12:00 am. I am also having trouble if the start time is before midnight like in a 11pm to 5 am shift.

=(IF(AND(S3<=$AG$97,S3>=$AG$73),(($AG$97-S3))*24,0))

S3 is the start time

AG97 is 6:00 am

AG73 is 12:00 am

Identify Distinct Start Stop Times?

Aug 21, 2014

I am attempting to create a datasheet to track the actual time an agent takes a break or lunch. Here is an example of the data that I am using.

name Date Lunch Sch Brk1 Sch Brk 2 Actual Time
BrandonHolt8/19/201411:10 8:30 1:20 8:24:20 Break
BrandonHolt8/19/201411:10 8:30 1:20 11:42:34 Break
BrandonHolt8/19/201411:10 8:30 1:20 12:57:46 Lunch

Because I have two break times, possibility of more depending on the agent, how do i create a formula that will look at this data, take the schedule time for say break one and only apply that against the time that is more in line with the closest actual time?

Calculating Start / End Time Between Night Shifts 24 Hours?

Dec 26, 2013

We have a person who work in 24/7 support. One person work passive 24 hour, but it 24 hours are divided in to next shifts: normal 06-18, over hours 18-22, night hours 22-06.So if we have some one who is supporting client say from 17h till 23h, we have next results:

Name Start time End Time 06:00 - 18:00 18:00 - 22:00 22:00 - 06:00

John 17:00 23:00 1:00 4:00 1:00

Is it possible to in time range enter formula who subtracted end time from start time, but taking into account 24 hours?

Finding Range Between Start Times Spanning Across Midnight

May 13, 2014

I have various start times for employees.

I need to find out the total movement in start times per week for the employees.

I have used MIN and MAX to find the earliest and latest start times, and then a subtraction to find the difference.

This works brilliantly until my employees who start around midnight.

If they have started before and after midnight, it takes midnight as the earliest time and 23:00 as the latest, giving a difference of 23 hours instead of 1 hour.

i.e.

Start Times
23:00, 23:15, 00:15, 00:30

Range of Movement
00:30 - 23:00 = 01:30

I've tried, =$B$9+($C$4>$B$9)-$C$4 but this does not work when the MIN reads 00:00.

Determining If Datetime Falls Within Start And End Date Times

Sep 25, 2013

I have been using this statement

if(and(c1>=a1:a144,c1<=b1:b144),"yes","no"))

And it just works for the first 2 values c1, c2 and doesn't fit for the others.

The case is i have more than one event at the same video and i need to confirm that no event was taken unless it is between start and end.

Here are some samples:

Start dtime End Dtime Event Dtime
16/09/2013 22:13:34 16/09/2013 22:14:18 16/09/2013 22:13:38
16/09/2013 22:15:57 16/09/2013 22:24:30 16/09/2013 22:16:02
16/09/2013 22:24:30 16/09/2013 22:33:49 16/09/2013 22:17:32
16/09/2013 22:33:53 16/09/2013 22:35:05 16/09/2013 22:19:02
16/09/2013 22:35:05 16/09/2013 22:39:57 16/09/2013 22:20:02

So as you can see there are more than one event between one start and end dtimes.

I had an excellent response last time I posted here, this time I’m stuck again with a new formula. I’m trying to calculated amounts between different times, but keep tying my self in knots with complicated IF formulas.

Is there an easier way to work out hours worked between 2 times, but too complicated things further I need three separate amounts so I’m guessing I’ll need three separate formulas

Hours between 00:00 – 06:00
Hours between 06:00 – 19:00
& hours between 19:00 – 00:00

An example could be, 05:00 – 20:00 should be 1,13,1
