Microsoft Access Date/Time Differences

How Much Time Has Elapsed Between Two Dates/Times. Employee Timesheets.

Q: I have a timesheet table with TimeIN and TimeOUT for each employee. How can I calculate the HoursWorked?

A: Working with times and dates in Access is easy once you know that each DAY has a value of ONE. So if you add 1 to 1/1/1990, you get 1/2/1990. If you add 0.5 to 1/1/2004 you get 1/1/2004 12:00 (which is HALF a day). If you need to figure out the difference between two times, just subtract them. That will give you the difference IN DAYS between those two dates. If it's a fraction, you're dealing with HOURS, just multiply by 24. Here's an example:


Here is a FREE VIDEO TUTORIAL that will walk you through an example of working with date and time differences. It's much easier to show you how it's done than to explain it here.

I teach the concepts in this free mini tutorial in my Access 206 course. These are full courses - over 60 minutes in length each. I spend a lot more time going over how to do this, in addition to lots more tips and tricks.
