With Microsoft Excel, you can create a worksheet that figures the hours worked for any shift. Follow these step-by-step instructions.
To calculate in Excel how many hours someone has worked, you can often subtract the start time from the end time to get the difference. But if the work shift spans noon or midnight, simple subtraction won’t cut it.
However, you can easily create a worksheet that correctly figures the hours worked for any shift.

A bonus Microsoft Excel tip
From the article 10 things you should never do in Excel by Susan Harkins:
Rely on multiple links: Links between two workbooks are common and useful. But multiple links where values in workbook1 depend on values in workbook2, which links to workbook3, and so on, are hard to manage and unstable. Users forget to close files, and sometimes they even move them. If you’re the only person working with those linked workbooks, you might not run into trouble, but if other users are reviewing and modifying them, you’re asking for trouble. If you truly need that much linking, you might consider a new design.
