My head's swimming right now so the solution to this problem may be right under my nose and I'm just blind to it.
I have a table with events, represented by an ID number, and the date/time the events occured. Each event is also attatched to a particular mission number. Looks kinda like this:
Mission EventID Time
Each Mission has different events like liftoff and patient contact, and I need to find the time between events for each mission. I'm trying to calculate the Time from inital call to mission end, from dispatch to liftoff, ect.
Do I need to put these times into my mission table as columns, Time1, Time2, Time3... or can I leave them normalized and still run calculations on them? :confused:
I'm trying to finish a query that calculates the time worked in the AM and PM, adds them together, then takes that away from the standard working day.
I've done everything else, but when I take the hours worked away from the standard day it always ends up with a positive number, regardless if they haven't worked enough hours.
I've looked through the forums and everyone is talking modules, but thats over my head.
Box 1 contains an employee's total weekly hours in hours and minutes: 40:00 Box 2 contains the actual total hours worked for the week: 35:30 Box 3 is the difference between Box 1 minus Box 2
I tried all the date/time functions to calculate the difference between Box 1 and Box 2 and none of them worked. I keep on getting an error message. Does anybody know how to calculate the difference between two sets of time (in hours and minutes)?
I've just started a new job and one of the things they have got me doing involves getting some extra reports out of some access databases they have for the phone system. I've managed OK so far but I'm stuck on regarding phone diverts.
Basic jist is, when reception is unmanned they put the phone on divert and when they come back they take it off again. Simple and this info is recorded in the log file which is pulled into access each night.
The problem is all of the information is kept in a single table which I run a query on to get the info to look like below. The info is exactly as it is in the table, just that I have limited it to the reception user and where the func is like *54* or *55*:-
The FUNC *54* means put on divert and *55* is off divert. What I need to figure out is the time between each of *54* and *55* and total them for all the data in the table (we have a table for each month). The problem I can see here is that occasionally the receptionist will put in the *55* first which doesn't mean anything so this bit would need to be ignored as only bits where its a *54* followed by a *55*.
Hope this is self explaintory and that someone is able to help. I have attached a CSV fle on the table so you can have a play with it if you can help.
I,ve made the following date fields in a form: begintime, endtime. I've also made a field Diff that calculates the difference between the two by the code : Diff = Format([begintime] - 1 - ([endtime], "Short Time"). Bij this code you can calculate the difference even over night.
But now I've got to calculate the part of the time someone worked between midnight and 06:00AM if that person indeed worked in those hours.
e.g. someone started at 16:00 end ended at 03:30. The part of time I need = 3:30 e.g. someone started at 01:00 end ended at 11:00. The part of time I need = 5
How can I accomplish this? I hope someone can help me because I'm :confused:
I'm trying to find the difference between 2 dates [Start_Date] and [End_Date], however I want to strip out out of hours work, which is [OOH_START] eg, 17:30 and [OOH_END], eg, 08:00. Also I need to strip out the weekends as well.
What I have is a table with three columns: Name, Start, End (the last two being a start time and end time column in 24 hour format). What I need to do is calculate the time interval in minutes between the start and ending times (this has been done already and quite easily). What I find myself stuck on is when the ending time exceeds 00:00 and the start time is before this. IE: 23:30 start, 00:30 end, which is 60 minutes (duh). I wind up getting a 23 hour time.
Is there a way that I can code up a query (has to be a query as the rest of the DB results rely on the correct minutes per person)? Appreciate any help in this
I have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
Code: SELECT [Message Tracking_tbl].[Date & Time Left], [Message Tracking_tbl].[Date Returned], [Message Tracking_tbl].ID FROM [Message Tracking_tbl];
I need to calculate (in a query) the Actual Time of a job. I have the start date, start time, end date & end time (all separate fields). This seems to works ok by subtracting the start from the end.
Then I need to calculate the Estimated Time (time it should have taken). This is done by taking the Quantiy divided by the Rate-Per-Hour. This seems to work out ok in the Query, e.g., 101000 / 15000 = 6.66667 hours. But when I display this result in a report as a "Short Time", I get 16:00 instead of 6:40. How can I get the correct display? The other problem is that I need to divide the Estimated Time by the Actual Time. This also gives me wierd results - I suppose because one is a decimal format time and the other is a "Short Time" format. How can I get the correct answer?
Hi, I wonder if someone can help me with the following problem:
I have a table with 2 columns,start time and end time, both containing time values in a four digit format, eg 0930 being 9:30am etc.
I have made a query to convert these into the standard format (eg 0930 becomes 09:30), using left/right and & functions.
Now I use the timevalue function to convert the string , eg 09:30m into a recongnised time value.
The problem is now I want to find the difference between the start and end times- but when i try a simple end_time - start_time formule it returns a long number which i dont understand, rather than just giving me the difference betwen the two times.
Im sure there is a simple way to do this which I dont know, can anyone help me out? Thanks in advance!

I need help to calculate time difference from the record above where ID is same. I have attached an example in excel with this request where I have if statement doing exacly what I want to do in Access. I have a table in Access that has three columns - as below
I have a field that works out the difference in time between two fields. However, whenever the end time goes past midnight, it calculates the difference as a minus figure. I understand that this is because of the date issue, but I cannot seem to find a way around it.
Here is what I have so far:
time_of_referral field. This is the start time. It is a short time field that is filled in by the end user.
time_of_arrival field. This is the end time. It is a short time field that is filled in by the end user.
Text31 field. This is not visible to the end user, and has the following control source =DateDiff("n",[time_of_referral],[time_of_arrival])
Text33 field. This is an unbound text box with the following control source =[text31]60 & Format([text31] Mod 60,":00")
This works out the time difference and presents it as hours and minutes.
I have seen solutions that add a day to the end time, but unfortunately this does not work when the end time DOESN'T go past midnight. Some will go past midnight, some won't.
I have created a database in Access where parents of students may come in and volunteer and receive free time credit from their employer (those companies who participate).
The database runs fine: Main table (demographics; student table; signIn/signOut table; and Volunteer Duty (a combo box that list all of the approved volunteer duties to qualify for the time credit) Every thing works perfect with the exception of my signIn/signOut form. After struggling with this for countless hours, I have settled for a manual entry of the signIn and signOut time, entered at the time of their start/stop times. I would like for it to be an automated function, but I have had such a difficult time up to this point I will settle for this method. What I NEED is to figure out how to make my "total vol hours today" field calculate the total volunteer hours at the time the parent "signOut".
If some of you Access MVP's can help with this I will be very grateful.
I have a [Time Job Started] field that is auto populated with now(). which has input of 1/29/2014 11:02:02 am. Then I have a [Time Job Ended], typed in by user that has input of 6:00 pm, no date value. Cant really do the date() + Time Job Ended, because the date can range since times can go through midnight.
I am trying to calculate time duration. DateDiff("n",[Hot Calls]![Time Job started],[hot Calls]![Time Job Ended]) if this formatted as "Short time" it returns 0:00.
I want to report this as HH:MM. so the result should be 6:58.
I'm trying to calculate the difference between start and end time, which works fine with:
Total Time: DateDiff("n",[tblTaskTimes]![StartTime],[tblTaskTimes]![EndTime])
However, this is for a database that calculates billable time in 10th of an hour. So, for example, 1 hours would be 1, 30 minutes would be .5, less than 6 minutes would be .1.
The format for this expression is set up to a general number, if that matters.
It's gotta be something in the formula like multiplying this by 24 (for 24 hours) and then dividing by something. Nothing I'm trying is working.
I have a subform in which I want to calculate the difference between a start time and finish time, the problem I am having is when the start time is on a different date to the finish time
Start 23:15 on 14th Jan finish 00:015 on 15th Jan, also I want the answer to be the number of minutes. The fields I have are
BatchStartTime Short Time BatchFinishTime Short Time BoilTime ([BatchStartTime] - [BatchFinishTime]) General Number.
There are many batches to enter per job and the MainForm has the StartDate as I didn't want to enter the StartDate for each batch.
I am VERY, and I mean VERY new to Access. I've been racking my brain all afternoon and googling like crazy. I just completed two levels of training on Access 2010 and have never worked with the program before. I already set up my tables and now I am on to querying. I have a table with several columns, two of which are "Start Time" and "End Time". I already created a query using the DateDiff function to calculate the time difference for each record. It output a new field with the time difference in hours. Now, I want to sum the totals of the time differences by month and I cannot for the life of me figure it out. My new query has Date (m/dd/yyy) and Hours.
I have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
The only issue is the calculation has to be done by time and so I have to calculate what time they left the message(so the difference between [Date & Time Left] and [Date Returned) [Date & Time Left] and when the rep returned the message which is suppose to be [Date Returned] but the problem with this field is the data entry is in date format (10/9/2014, 00/00/0000) of Date and not Date and Time like the [Date & Time Left] field, so I don't know what to do now. Not sure what to do now not a database that create or have allot of control over.
I want to be able to display the result of a difference between Date/Time values in "HH.MM" format (i.e. yes I want the result in decimals and I don't want Access to round up or down just because it feels like doing it!). I have used the following:
Example 1:
Dim ActualManHours as Long ActualManHours = (txtEndTime.Value - txtStartTime.Value) * 86400 txtActualManHours.Value = ActualManHours
Example 2:
Dim ActualManHours as Long ActualManHours = DateDiff("h",txtStartTime.Value, txtEndTime.Value) & "." & Format(DateDiff("n",txtStartTime.value,txtEndTime. value) Mod 60, "00")
Example 3:
Dim StartTime as Double Dim EndTime as Double Dim ActualManHours as Long StartTime = CDbl(txtStartTime.Value) EndTime = CDbl(txtEndTime.Value) ActualManHours = EndTime - StartTime txtActualManHours.Value = ActualManHours
I would like to add time elapsed since an entry was made excluding weekends public holidays and calculating 8 hours a day (from 6am to 2 pm) since the entry was made till the generation of the report.
How shall I approach this in terms of programming ?
