I have two fields in a query: "Date Completed" (mm/dd/yyyy) and "Time Used (hours)" (nn.n). I am trying to calculate a third "Date Started". Assuming an eight-hour day, I am trying to use the expression [Date Completed] - [Time Used (hours)]/8 but I can't figure out which Date/Time functions to use to convert my dates and hours to the same units to do the calculation and then back to a date again. I am using Access 2007 and am not all that competent with it. Thank you in advance for your help!

You can try the following. DateValue(DateAdd("h",-[Time Used (hours)] * 3),[Date Completed])) If you are trying to work this out for weekdays only, then you will probably need something more complex. If persons work on every day of the week then this should work to give you the starting date.

I was wondering if anybody knows of a formula to allow you to do calculations based on time. In other words, say I want to put a list of songs on a CD and their durations.

So for example, using the information below: Ghostbusters - Ray Parker Jr. --- 5:23 (Just a guess) Phantom of the Opera Overture --- 3:55 (Another guess) Instead of 8:78, I'd want to see 9:18 Can this be done?

Hello, I am new to excel and have been assigned the task of creating a file that breaks down the amount of time each of our employees spends on different projects. Most importantly I want to create a rollup sheet that shows the total number of hours all the employees have spent on the different projects (there are 6) for the current week. Is there any way for excel to figure out the current week then add together the hours all the employees worked on these 6 projects? Thanks in advance.

I am working with a colleague to create a spreadsheet to rank supervisor performance through several aspects of the average performance of their employees. We have been given a similar spreadsheet as an example of what is needed. I am looking at it, and initially cannot understand what in the world some of the calcuations are meant to do. Here is one that is meant to calculate the "ranking score." It is a percentage determined by a target percentage and the person's actual performance percentage: =IF(IF(C3>0,(C3/B3),200)>200,200,IF(C3>0,(C3/B3),200)) As far as I ...

I made a spreadsheet to combine f/stop, shutter speed, and film speed into a single number. This number represents how many stops the exposure was taken from a sunny 16 setting. For example, if I'm using ISO 100 film, a shutter speed of 1/125 sec., and an f/stop of 11, it will calculate to about .8. Ok, now for the fun part. When I enter a shutter speed into a cell, I just input the denominator because all the numbers are just reciprocals of their respective shutter speeds. For example, for 1/125 sec, I enter 125 and let the inner workings take care of it. The problem is when...

I have a simple spreadsheet calculating the hours worked by a person, In the columns i have start time, end time and hours worked. The columns are formatted into hh:mm.
