# Check Date & Time For Missing Hours

Aug 7, 2007

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).

## Adding Time More Than 24 Hours To Date Time Stamp?

May 30, 2012

I want to add hours to a date-time cell to get result in date-time.

Format of cell A1 is d/m/yy h:mm AM/PM
Format of cell A2 is General
Format of cell A3 is d/m/yy h:mm AM/PM

I want to add A2 (number of hours) to A1 to give A3.

The formula I used is A3=A1+Time(A2,0,0)

The formula works perfectly fine when A2 is less than 24, but when A2 is more than 24, the date doesn't get changed.

## Fill In Date And Time Where Missing On 3 Minutes Interval

Jul 20, 2012

I am having trouble getting a VBA code to do the following:

2012/05/01 00:00:00
2012/05/01 00:03:00
2012/05/01 00:06:00
2012/05/01 00:15:00
2012/05/01 00:18:00

From this above to this below

2012/05/01 00:00:00
2012/05/01 00:03:00
2012/05/01 00:06:00
2012/05/01 00:09:00
2012/05/01 00:12:00
2012/05/01 00:15:00
2012/05/01 00:18:00

There are data entries next to these time stamps. I am able to create just the time stamps starting at the beginning and ending at the end of the month but I need it to fill in missing entries in a data set. The code below works but only some of the time. I have tried a few different things but nothing works.

Code:
Sub Insert_missing_3min()
'Inserts a row with the date and time where the missing date and time stamp is and a zero next to the date added.

Dim min3 As Date
Dim CurTime As Date
Dim CurCell As Date
Dim NextCell As Date

min3 = 3 / 24 / 60

## Time Conversion: Convert A Time From Hours/Minutes To Hours/Tenths

Oct 10, 2009

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?

## Excel 2010 :: 32bit - Microsoft Date And Time Picker Control 6.0 Missing

Nov 7, 2013

I am trying to add a calendar picker to Excel 2010. Everything I read online says that it is possible, you just need to use the ActiveX control "Microsoft Date and Time Picker Control 6.0", and that it should be listed under Developer Tab -> Insert -> More Controls ->... But it's not listed.

I also tried downloading the Microsoft Windows Common Controls-2 6.0, but when I tried to add it to Excel using "Register Custom...", it says "Cannot register this control".

Why this control is missing? and I can't add it?

## Adding X Hours To Date & Time

Aug 23, 2008

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?

## Add X Hours By Condition To Date & Time

Feb 22, 2008

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.

## Time/date Tracking Only During Business Hours

Mar 19, 2007

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?

## Calculate Date/time Format Over 24 Hours

Nov 22, 2006

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.

## Subtract X Working Hours From Date & Time

Jun 20, 2008

I am trying to subtract 8 hours from a date/time. What I need to do is to capture that lead time using only weekdays, and working hours of 8am-5pm.

For example:

Date/Time
6/23/2008 9:18AM (Monday)

Subtracting 8 hours from this scenario would give me
6/20/2008 10:18AM (friday)

## Adding Date And Time Minus Not Working Hours

Sep 11, 2011

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.

## Macro To Recognize Date That Is 48 Hours Before Current Time

Feb 15, 2012

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:

xxxx........555-555-5555...........5555555............2/12/12
xxxx........444-444-4444...........4444444............2/15/12
xxxx........123-456-7890...........1234567............2/10/12

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.

## Separate Hours Based On Time / Date / Holidays

Jan 9, 2013

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.

## Date/Time Calculation For WeekEnds/After Business Hours

Jul 23, 2007

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.

## Formula For Date And Time Difference Using 8am-5pm Work Hours

Oct 22, 2008

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:

A1 2008/10/10 16:30
B1 2008/10/11 09:30
C1 8:00
D1 17:00

B1 = reported recorded in db
C1 = work day start time
D1 work day end time

Where the answer should = 2 hours.

I am not an experienced excel user and so far the only formula I have now is: =TEXT(B1-A1, "d:hh:mm")

And how do I account for weekends?

## Calculating Date & Time Difference: Result In Hours Only

Sep 29, 2006

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.

## 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.

## Time Difference In Hours / Minutes And Seconds Between 2 Date / Timestamps

Aug 22, 2012

I have

Code:
Start date 21/08/2012 23:21:30

is there a formula to get the time difference in Hours for example in this case its 72:01:15 72 Hours, 1 minute & 15 seconds

## Subtract Date/time And Get Elapses Days, Hours, Minutes, Etc

Jul 20, 2007

I want a forumal to do in excel.

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 have created a user form for some data submission. I am looking for a macro to check the text boxes, that I have named appropriately i.e. Name, Address, City, State etc. , to make sure there is something entered.

If nothing is entered it needs to return a msgbox that says what field is blank.
