Calculate Total Time Spent on a Job in Hours, Minutes with DateDiff in Microsoft Access, Time Clock

Learn how to calculate the difference between two times in this Microsoft Access tutorial. You can use this for employee time clocks, job costing, or just about any database where you need to figure out the difference between a start time and an end time in minutes and/or hours. Adam from Fort Dodge, IA (a Developer Student) asks: I have a series of jobs that have a start date/time and an end date/time. I need to be able to calculate the total time worked on each job so I can bill my customers accordingly. Additionally, sometimes the job might start on a Thursday and end on a Monday. I need to exclude weekends, after hours (5pm to 8am the next day) and lunch breaks (noon to 1pm). How do I do this? BONUS FOR CHANNEL MEMBERS: Silver Members and up get access to an EXTENDED CUT of this video which covers additional examples.
