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.

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?

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?

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 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.

I have a user form with textBox1 = start time (entered as "[h]:mm") and text Box2 = finish time (entered as "[h]:mm"). I would like textBox3 to display the difference between the start time and finish time as a general number!

For example Start time: 21:00 Finish time: 06:30 Hours worked: 9.50

What I need is a formular/vba code that can divide hours into different time ranges. The picture below shows an explanation.

In example 3 there time range analyzed goes from saturday till monday. Here Sunday should get 24 hours and the time range 23-08 for weekdays is at this point 00-08.

I've tried everything I could imagine to get this one working,

I'm battling to come up with the formula to calculate time and a half and double time. My boss wants me to show the overtime worked AFTER 40 hours has been worked. I have attached a copy of my spreadsheet.

I have this spreadsheet where it is basically call center data so in one of the column it shows time of inbound call as example (21:12:05) and other columns shows specific notes about that call example if product was sold on that call or not. So I am trying to find trend that during what period of time in a day maximum product was sold. Example I want to set some criteria that from 8 am to 10 am, 10 am to 1 pm and so on and then to find how many products are sold. So what I am looking is how can i extract hours as numbers only? from time stamp? I tried using =RIGHT(a1,2) but its not working and it messing with the number format.

We have a bar code scanner that scans employee IDs as they come and go each day. Beside the ID is the date/time stamp in the next column. They do not always come in in the same order they leave, so I am looking for a solution that will collect the in and out time for each ID, then add those times beside each employee name, and add them for a hourly total.

I am replicating a Matlab program which calculates tide levels at different times of day. I need to replicate it in excel to speed up data analysis and I am nearly there.

what happens is I need to apply a time offset to the time of high tide at port a based on the time of day, so if it is:

between 00:00 and 06:00 the high tide at port b is 81.6 minutes after the peak at port a between 06:00 and 12:00 the high tide at port b is 74.56 minutes after the peak at port a between 12:00 and 18:00 the high tide at port b is 81.75 minutes after the peak at port a between 06:00 and 12:00 the high tide at port b is 79minutes after the peak at port a

I tried this formula, where CO2 has the time/date of the high tide at port a: =IF(CO2<0.75,IF(CO2<0.5,IF(CO2<0.25,CL2+(81.6/(24*60)),CL2+(74.56/24*60)),CL2+(81.75/(24*60))),CL2+(79/(24*60)))

The problem is the high tide on 07/01/2005 07:45 is read as 38359.32 rather than 0.32 - is there any easy way to tell excel I'm only interested in the time not the date? I have this spreadsheet setup now to do all the other bits required and i is just the timing that is a problem.

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?

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

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 am trying to create a spreadsheet to determine hrs per time interval

i.e 06:00 - 14:00 14:00 - 22:00 22:00 - 06:00

So a start time of 06:00 and finish time of 14:00 would show 8hrs in first interval and 0 in the other 2 and a start time of 10:00 and a finish time of 18:00 would show 4hrs in first interval and 6 in second and 0 in last

I've currently got start time in A1 , finish time in B1 and want hours for interval 1 in D1 , interval 2 in E1 and interval 3 in F1.

I'm trying to use conditional formatting to highlight phone calls that came in between certain hours.

The call times are in the custom format h:mm, although it could easily be changed to an Excel time format. I'm using Excel 2002. I want the cell to have a different fill color if it falls within particular time frames.

Example:

If the call came in between 22:00 and 23:59 color is light green. If the call came in between 23:59 and 08:00 the color is yellow.

I'm creating a calculator to determine the distance & travel time on a xy grid for a game. I'll share what I have so far to display the big picture. Here’s what I’ve accomplished so far:

#1) Cells A1 & B1 are dynamic, they are frequently changed so distance and time may be displayed. Cells A2 & B2 do not change.

#2) I use the following formula to determine the distance between cells, displayed in C2: =SQRT((A2-$A$1)^2+(B2-$B$1)^2)

#3) Next I multiply C2 by a number so that distance is measured correctly per unit type for this game. (I hide this column). Therefore, cell D3 has the following formula: =C2*20

#4) Now my problem, cell E3 - Correctly displaying time. I have the following formula in E3: =TIME(0,D2,0)

This works great!! That is until the time goes beyond 24 hours, then it rolls over. I've tried right clicking and setting the custom format of E3 to [hh]:mm, it still rolls over. I’ve also tried setting formatting to d:[hh]:mm, if I do this then the output time displayed is incorrect.

Ideally I would love a simple fix so that the time will roll over and show days. (I would like a display similar to d:hh:mm).

I’ve done a fair bit of research online and either I'm missing something simple or this is more complex than I thought. And not to make this any more confusing, but I would love whatever I accomplish here to be useable in compatibility mode ...

Basically I want to be able to type a number and have a colon inserted two spaces to the left. So 123 would become 1:23, 1234 would be 12:34 and 12345 would be 123:45.

I'm working with anywhere from one to several thousand hours in a spreadsheet. I'd like to be able to use a time mask like this:

Just basic enter a start time in column A a finish time in column B and column C gives you total in hours and minutes and then maybe a way to sum those hours and minutes. how to do "Math" on time and how it should be entered (formatted) for it to work properly.
