# Calculating Time (24 Hour Clock)

Jul 16, 2012

I've calculated the time of hours worked by staff using th 24 hour clock - "hh:mm" format.

When summing up the hours, it goes a bit haywire, i.e.

Staff A = 12:30
Staff B = 14:00
Sum = 02:30

Total should equal 26:30 (26 and a half hours), however I get returned 02:30. I assume it is down to the 24 hour clock and I so I tried adding 24 to it in the formula bar to get the right answer and it didn't work.

## Calculating Time Across A 24 Hour Period

Nov 6, 2007

Calculate certain time increments for various work-shifts. I have a start time,finish time and increments of time across the spectrum of 24 hours. There are also multiple start time across the 24 hour period with some start times begining on one day and ending on the next day.

Example

In B5 Startime is 22:00
In C5 Finishtime is 06:30

In I3 increment begins at 00:00
In I4 increment ends at 00:30

The employee working the shift from 22:00 - 06:30 would fall into the time increment of 00:00 - 00:30 where another employee working a different shift (08:30 - 17:00) would not. I'm looking for a formula that would return a 1 in a cell if the employee fell into the 00:00 - 00:30 time increment and a 0 in a cell in the employee did not fall into the time increment.

## Calculating Data Within Past 24 Hour Time Period

Jun 7, 2014

I am a flight instructor and legally we cannot work more than 8 hours in any consecutive 24 hour period. I'm trying to create a spreadsheet that will calculate the totals from that 24 hour period for me.

Right now I have something that sort of works, but not the way I would like it. I have a column for "time" that has the date and ending time of the flight and I am using that as if the total flight occurred at one moment (the ending time).

So, for instance let's say I did these flights

1: 8AM-10AM (2 hours, clocked at 10AM)
2: 11AM - 2 PM (2 hours, clocked at 2PM)
3: 7AM-9AM the following day (2 hours, clocked at 9AM)

If I have my formula calculate the time for 9AM the following day (totaling the past 24 hours) the first flight won't be included in the calculation since the hours from that flight is only imputed at 10AM. The formula would read 4 hours rather than the (actual) 5 hours.

Here is my workbook : 8 hour calculator sample.xlsx

Here are the formulas I am using

The time is formulated at date and time, with time being the ending flight time

The start time for the calculation is

[Code]....

end time is just =NOW()

Total calculation is

[Code] .....

All I'm trying to do is use the totals under "flight start" and "flight end" instead of the end flight time I had to put in under the date column.

## Changing Date/time To Run A 12 Hour Production Schedule, And Not 24 Hour

Sep 4, 2006

I have created a daily schedule which has a number of factory variables taken into consideration which determine the date and time a particular product should, barring any mechanical problems, come off the machine. (see attached spreadsheet).

The date at the top will be editable by me only so that when I update the production quantities, the “date/time off” column automatically re-adjusts to the remaining quantities.

The formulas are a little long winded, but I have left them that way whilst I try and develop it. I should be able to figure out how to condense them later.

My problem is that the “date/time off” on the right works excellent, but over a 24 hr period.

Ordinarily, we work a 12 hour day (6am to 6pm) with overlapping shifts to cover breaks, and 20 mins warm up at the start of the day for the machine, thus maximising a 12 hour day.

Of course if demand exceeds the allotted time we put on overtime.

Is it possible to specify that normal days are only 12 hours so that if a product exceeds 6pm, it flows into the next day with the balance starting at 6:20am?

And, if the production for the week exceeds the time could I stipulate particular days which we deem are suitable for overtime? Ie, we decide Wednesday is a 14 hour day and not 12.

I had toyed with the idea of creating a 365 day table/calendar, on another worksheet which would have its individual allocated hours in an adjacent column and somehow link them to the date/time off, perhaps by way of a VLOOKUP, but I have been chasing my tail trying to figure out how to implement it.

## Convert To 12-hour Time From 24-hour Time

Mar 7, 2008

I'd like to convert from 24 hour standard time to 12 hour time using VBA code. For example: instead of 13:00 I need 1:00.

## CONVERT 24-Hour Time To 12-Hour Time

May 8, 2008

I have a list of FLIGHT departure times that are listed in MIL TIME, however, there is no : in the format. Its just 4 or 3 digit numbers. I need to convert these to time in 12-hour clock. If I go to FORMAT/CELL/TIME and select 1:30pm it simply makes the time ZERO!

## Calculating Episodes Per Hour

Jul 30, 2009

I need to calculate the number of calls my operators take per hour of the day in order to calculate the busiest times of the day. Each call is time stamped and captured but now how do I calculate the total number of calls taken between 07:00:00 and 07:59:59 etc etc for the whole 24 hour period?

## Select A Time From A Clock?

Jun 12, 2013

I've linked some cells to the date picker function so a date can be selected from a pop-up calendar.

Is it possible to do the same with a clock function?

## Use Excel As Time Clock?

Sep 6, 2005

I currently use a manual time clock for my employees to punch in and out. I then use Excel to tally their times. This is very tedious and error prone.

Is it possible to use Excel as the timeclock itself? I know that the employee can enter the time in a spreadsheet manually. But this also opens the door for error and potential dishonesty.

What I am looking for is, if the employee can punch in and out by doing a keystroke and Excel uses the computer's clock to timestamp.

## Time (clock) Times A Number

Apr 2, 2009

I have a start time in one column, end time in another and a column with the difference between the two. In another column I have profit. In the last column I have profit per hour where I divide the profit by the hours, but since one is hours and the other is a number it gives me an error.

## Time Related To 24hr Clock

Jun 22, 2009

What i try to achieve is: from 00:00hrs to 24:00hrs = 24hrs which is 1.0 day
Have made the attached spredsheet to calculate it correctly to 1 day. But if you look on the attachment the "total hrs" is saying 00:00 (it transfers to 00:00 when i am putting in 24:00). Basically how am I able to make Excel to display 24:00 insted of 00:00. Maybe there is an add ins availible like the pop up calendar but for times instead.

## Time Clock And Converting To 3 Min Increment

Jul 8, 2009

Okay I have a basic Time clock calculation in excel (i.e.-(timeout1-timein1)+(timeout2-timein2)="Total time"). What I need to do is convert the "Total time" to be changed to 3 min increments. I don't know if that is the best way to put it but let me show you the chart for the conversions.
3 mins=.05 hrs, 6 mins=.10, etc etc etc.

So lets put this into us

A1 (timein1)= 6:42 AM
A2(timeout1)=11:30 AM
A3(timein2)= 12:00 PM
A4(timeout2)= 5:00 PM (17:00)

So A5(Total Time)=9h 48min, but I need it to equal 9.80 hrs because with the conversion, 48 mins is .80 of an hour. So how can I set up A5 (Total time) to automatically do this calculation? This website is how I would like it to work http://www.1728.com/timecard.htm

## Calculating Total Hours Worked By Group Of Employees For Certain Hour

Mar 23, 2013

I need creating a formula that will tell me the total number of employee hours worked during a certain hour (6:00 AM) for a particular department. Some employees clock in at 6:00 AM, some clock in at 6:30. Here is the current formula I'm using which only tells me the amount of employees in the department not how many hours worked . I have three employees that clock in at 6:00AM and one at 6:30AM, the total I'm looking for is 3.5 but my formula gives me the result of 4.

C5:C1446 is a list of departments
T1503 is the 6:00 AM
D5:D1446 are the Clock In times
K5:K1446 are the Clock Out Times

=SUMPRODUCT(--(\$C\$5:\$C\$1446="Shipping"),(\$T\$1503>=\$D\$5:\$D\$1446)*(\$T\$1503

## Time Countdown - A Live Clock In The Spreadsheet?

Nov 5, 2011

I need to calculate how much time I've got left before the earliest order needs to be despatched (it might be 2 or more on every day). This wouldn't be a problem if orders would be placed daily. But for every item it varies. For example: for "X" product there is an order in 3 days time to be despatched at 19:00. I have built a live clock in the spreadsheet but I can't work out the formula.

P.S. Also I need two time formats, first - days(text) hh:mm second - just a numeric value that can be formated as [hh:mm].

## Running Clock In Excel With Different Time Zone

## How To Make Clock To Show Time In Words

Aug 29, 2013

I want to make a Word Clock. Instead of showing the time as "12:30" I want it to show the words "It is half past twelve"

To Do this I've created a Square of Letters on an excel sheet (one letter per cell!) with black letters and black back grounds, when it is 12.30 I want the relevant letters to (cells) to change the text coulor to white so it shows up.

The cell I'm using are from D8 to P19 and the time is shown in A1

So lets say at 12.30 Cells D9, F12, H14 and M16 need to change from Black Text Colour to White Coulour,

I need a code or some VB that says "If A1 = 12.30 the Cells D9,F12,H14,M16 = White Text Colour, if not Black Text Colour".

## Time Clock Six Minute Rounding Formula

Apr 27, 2007

I am trying to figure out the written formula for needing this answer:

For a time clock with 6 minute rounding.

If I type in 8:20 as the arrival time, I need it to round to 8:18, so that the final time will be in tenths.

Here is the rounding:

Actual Rounded Minutes in Time Clock
:57, :58, :59, :00, :01, :02
:03, :04, :05, :06, :07, :08
:09, :10, :11, :12, :13, :14
:15, :16, :17, :18, :19, :20
:21, :22, :23, :24, :25, :26
:27, :28, :29, :30, :31, :32
:33, :34, :35, :36, :37, :38
:39, :40, :41, :42, :43, :44
:45, :46, :47, :48, :49, :50
:51, :52, :53, :54, :55, :56

Anything in the same line will round to the bolded time.

Example: I arrive to work at 8:09 and go to lunch at 11:59, it will round to 8:12 and 12:00, making my time worked 3:48 or 3.80. Then I get back from lunch at 12:59 and leave at 17:14, which will round to 13:00 and 17:12, making my time worked 4:12 or 4.2 for the 2nd 1/2 of the day and 8:00 or 8.0 hours for the day.

Time In----------Time Out----------Total Time----------Decimal Time----------Total Hours
...8:12.................12:00..................3:48......................3.80
..13:00................17:12..................4:12......................4.20..........................8.00

The problem is I want to write the actual time and not have to round everything myself and yet I need the decimal time to match what my time clock actually calculates from.

My current formula for the decimal shown above as 3.80 is this: =(HOUR(F7)*60+MINUTE(F7))/60
My current formula for the total time for the day (regular hours) is this: =IF((((E7-D7)+(I7-H7))*24)>8,8,((E7-D7)+(I7-H7))*24)
My current formula for overtime is this: =IF(((E7-D7)+(I7-H7))*24>8,((E7-D7)+(I7-H7))*24-8,0)

This is not a time clock, it is my personal copy of what my time for the week was/is, so that I can compare it to the actual time card that I have to sign off on.

## Changing Elapsed Time Into Time As Portion Of An Hour

Sep 11, 2013

In A1 I have 35 min elapsed time and need to change it to time as a portion of an hour. It reads the 35 min as TIME, therefore I am currently using

=IF(A1>=0.5,A1-0.5,A1)*24. Output is .58, which is perfect.

(output column formatted as a number)

Likewise 3:28 becomes 3.47.

## Time W/in Each Hour Of Day Btwn A Time Range

Dec 20, 2007

I need a formula to calculate the time (in hours/fractions of an hour) that is "covered" for each hour of the day between a range of times. In other words, I have a "START TIME" and an "END TIME" and for each hour of the 24-hour clock, I want to know how much time this range covers.

For example, if my start time is 3:30am and my end time is 5:15am, for the 3am hour, the formula would return 0.5 hours, for the 4am hour it would return 1.0 hours, for the 5am hour it would return 0.25 hours, and for all other hours it would return 0.0 hours. The range of START TIME and END TIME can be up to 24 hours (but not more), but the tricky part is that the START TIME can be on the day BEFORE the END TIME (e.g., START TIME of 10:35pm and END TIME of 5:45pm the next day).

## Time Sheet :: 12 Hour Time Format With AM/PM

Mar 13, 2008

I found a formula for calculating time in the HH:MM AM/PM

=IF(B1<A1,B1+1,B1)-A1

This formula was to give me total hours in the cell for which it is entered, and cell format for the formula was in military format.

I cannot find this post. The formula worked in OpenOffice Calc program, but when it came to converting to excel, I came up with #value!

I want to enter the time in 12 hour format and using am/pm to designate. I am making it for someone to make work schedules with and they do not know military time.

Apr 2, 2009

I have a start time in cell A1 (say 9am entered as 900), cell B1 has a time interval (25min), Cell C1 gives total (925). Cell B2 has the next time interval (56min). How do I get cell C2 to give total of 1021 rather than 981? Values in columns B and C continue on down.

## 24 Hour Double Time

Apr 21, 2009

I have a timesheet which for certain days of the year calculates double-time. What i would like to do is have a formula that gives double time for a 24 hour period. I have a formula setup with a start time and end time for my double time, but it wont stop at midnight.

## Hour (0-23) To Time In Excel

Jan 9, 2014

I get data in the form of an .xls worksheet that includes a date column and an "hour" column. The hour column contains 1-2 digits representing the hour of the day (0-23). I need to be able to combine the date and time fields for graphing, searching, and sorting the data. No matter what I try, I can't get excel to recognize the hour as the time of day (e.g. 2 = 2:00am, 16 = 4:00PM, etc). The data sets tend to be large and I get new data in the form of new .xls files often, so a script to convert the data is probably not a good solution.

## Count Time (entries Per Hour)

Oct 7, 2008

I have a bunch of data and I want to be able to count the number of entries that fall within each of the 24 hour increments in a 24 hour clock. (military time)

For 12:00:00 all times would be between and including 12:00:00 and 12:59:59

Column B | Count
------------------
12:00:00 344
13:00:00 44
14:00:00 5

## Working With Time: Blocks Every Whole Hour

Aug 1, 2007

I have a spreadsheet that users input the temperature each hour, for a 24 hour period. The time used is 24hr clock, as example, cell A1 will be 03:00, and cell B1 would be the forecasted temperature.

On another sheet, the user inputs the temperature for the specific time a airplane is going to take off, i:e: 07:32. Is there a way I can have the second sheet look back to the first sheet and grab the temperature for the correct time (using the hour block it falls into). The first sheet time blocks are every whole hour, i.e 08:00, but on the second sheet, the time could be any hour/minute, 07:32.

## Convert Hh:mm.* To 12 Hour Time Format

Jun 12, 2008

I have a ton of time in the above format (hh:mm.*) that needs to be converted to a 12 hour format (2:15 PM). I'm not wonderful with formulas, but if it's explained "simplistic" enough, I can probably get it. Please help - I've googled this to death every possible way. I can go in an manually change 19:37.5 to 7:37 pm - but it will take me FOREVER!
