I have a problem concatenating time in excel if it is of Date + Time format..
What formula do I use to just add the time by, say, 3 hours? I'll need to use, say cell B2, which will add 3 hours to it.. What formula do I use?

I have a data of complaints where I need to present it to the Management in such a way that the SLA period of 8 hours does not pass. Our office working hours are 7 AM till 7 PM. The complaint received should be escalated to concern section within 8 Hours of SLA time. I have the list of dates with received time. The complaint which could not be escalated today would be escalated next day. In this case is should deduct 12 Hours (7 PM to 7 AM, Non-working hours) from the time. How can I insert escalation date so as that it would deduct non working hours from it.

find a formula that will calculate the hours between the two below values but only take in to consideration the business hours (from 9 to 17) and exclude any weekends?

So I'm having a problem trying to make this scheduling sheet.. What I did was row a would be the employee list then b,c,d and so on are mon-sun Originally in b1 I would put like 9am-5pm and c1 8-4 and so on and in row i I put the total and added a sum function but somehow it wasn't able to calculate. So then I redid the whole thing this time in row b1 i put 9am and c1 5pm and so on and again I put the total and added the function and it still came out wrong..

I have a started time of say 8am from cell B3. I want to know what time it will be when I add a full number (hours) from another cell. For example A3+B4 where A3 is 8:00 A.M. and B4 is 4.04. I'm looking to get the a result of 12:04 P.M.

A B 1 4/1/09 12:15 2 4/2/09 10:00 3 4/4/09 8:10 4 4/6/09 9:00 5 4/8/09 5:00 6 4/11/09 7:00

I need to add up hours worked of last 3 days including current day. The date column does not contain everyday's date. How do I formulate a cell for date entry and another cell will show the sum of last 3 days including date not shown and date entered? E.g. If I enter date 4/6/09, result should be 17:10 hrs; 4/11/09, result should be 7:00.

When I am converting a time from Hours/Minutes to Hours/Tenths, Excel is not converting it consitantely. EXAMPLE: 1:15 = 1.25. When I format the cell to present only one place past the decimal point, sometimes the cell will round up to 1.3, and other times it will round down to 1.2. What am I missing?

Column 1: Date Call is received by helpdesk Column 2: Time Call is received by helpdesk Column 3: Drop-down list indicating Priority of call (High,Medium,Low)

In Column 4 I want to enter a formula that adds working hours only to the date and time entered in Columns 1 & 2. The time added will vary depending on what is entered in Column 3 (e.g.: if priority is High add 1 hour, Medium add 2 hours, Low add 3 hours). The working hours i need to adhere to are 09:00-17:00, Monday-Friday.

i work dispatch at a company and we're trying to track how long it takes for a technician to arrive on-site. my worksheet currently includes the date of call-in (E1) , time of call-in (F1), Service Date (G1), Service Time (H1), among many other field. the easy solution is to use the formula (G1+H1)-(E1+F1), and use the answer as the total amount of time, but the problem is if a customer call in at 3:00 PM and we service them at 9:00 AM the following day, it looks like it took 18 hours to arrive on-site, when in reality, since we close at 5:00 PM and open at 9:00 AM, we only took 2 hours to arrive on-site. is there any formula i can write to account for non-business hours and weekends, or is this a bit above what i should expect from excel?

I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

I have a column A with some dates at this format "dd-mm-yyyy hh-mm". In this list, some hours are missing, and I don't know which ones.

In order to find the missing hours, I created an additional column B, displaying all the hours, this way: B1=01-01-2006 00:00:00 o B1=A1

And then : B2=B1+"01:00:00"

Then, in column C, I compare both columns A and B: C1=IF(Value(B1)=Value(B2),ok,missing)

As a result, I first get some "ok", and then more and more "missing" statements, even though the dates look the same.

I checked the numerical values of my dates. At the first "missing" statement, I saw that there is a slight difference in the numerical values, at small decimals...

Can you tell me how to define my date /time in a good way, in order to avoid this kind of problems, please? (I could take the int part of the numbers, but this could lead to further errors, so I prefer to define my dates in the right way, from the beginning).

I'm attempting to make a simple time sheet for a handful of employees. I'd like to enter the clock in time and clock out time for each day. The end cell should be the running total for the week. The tricky part for me is having the formula subtract an hour for each day that is over 5 hours.

I am trying to find a way to calculate the number of hours between date/times found in separate rows. The attached data set will help to envision what I am talking about.

For each couple of rows, I need to find a way to calculate the number of hours elapsed from row 1 to row 2. In the first example, to calculate the number of hours between 12/2/2009 8:56:51 and 12/4/2009 6:35:27.

I want to find the hours worked in day shift and night shift. Day shift is from 06:30 to 18:30 and night shift is from 18:30 to 06:30. Listed below is an example of my date/times.

Note that the night shift carries over to the next day.

I have a spreadsheet that contains a list of names/numbers/dates and I have to manually go through the list each day highlighting the row if it contains a date that is more than 48 hours old. How to accomplish this in a macro? Example:

That is the layout of the spreadsheet so I would have to manually highlight rows 2 and 4 because the date in Column D is greater than 48 hours ago. The range is A1:D25 and the cells are changed/updated daily.

I calculate total labor hours entered into a CRM system and use it for various reports, but it's incredibly inaccurate for the following reasons:

Any labor put in between 6pm EST and 8am EST from Mon-Fri is considered "on call"All labor from Friday 6:01pm - Monday 7:59am is considered "on call"Labor entered on a company recognized holiday is considered "on call"Not every employee takes call

So, what I'm trying to do is take the total labor and pull out only the hours entered outside of the criteria above. If it were simply based on time during the week, i'd be fine, but I have no clue how to do everything else.

In the end, my new labor hours would be split into "Business Hrs. Labor" and "On Call" labor.

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 need to enter a formula that calculates the time a report is received from the time it was recorded in our database. therefore, it needs to exclude non working hours. here are the fields:

Instead of calculating a time difference manually I want to have a formula do it for me. What I want to achieve goes as followed:

08/06/2006 04:33 12/06/2006 01:05

Time difference is 92:32 [hh:mm]

another example:

09/06/2006 12:42 12/06/2006 11:35

Time difference is 70:53 [hh:mm]

So instead of getting 92:32 and 70:53 by calculating it myself I would like to have a formula do it for me. Otherwise I'll have to invest a lot of time to get the information I need.

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.

Assuming that a workday is from 8:30am to 5:00pm. (also need to not calcualte Saturday and Sunday but this example doesn't show it).

Wednesday, 7/18/07 at 4:00pm (minus) Friday, 7/20/07 at 9:00am (should equal) 10 hours or 1 day, 1 hour and 30 minutes.

Basically what I want to do it determine how much work time has elapsed from the time a message was left on voicemail to the time that someone picks that message up. We only want to assume that a message can be retrieved duruing business hours but a message can be left at anytime!

I m Trying to add some features to it and run into an issue. Here are the fields we are working with!

A1= 13:30:00 17/12/2008 (in other words 1:30pm on date given) - Need to know proper cell number format!!

B1= 23:00:00 (this represents 23 hours) - format for cell is [h]:mm:ss

C1= Unknown function (This field is my problem!!) Answer here SHOULD be "14:30:00 16/12/2008"

I need a function for C1 (using A1 and B1) that will give me the time and date 23 hours earlier or however many hours:mins:secs is specified in B1! Also need to know what number format to use for both A1 and C1

From an outside source, a date is brought into one cell, and time is brought into another. Is there a way to combine them into one cell with the format of m/d/yyyy h:mm?
