Hi! I am Dennis Taylor, and welcome to Excel 2007 Working with Dates and Times. Whether you are using Excel to track order and shipping dates, calculate the age of your inventory, or tabulate the hours worked on a project, you need to understand how Excel stores date and time data. And although occasionally problematic, most of these techniques are pretty easy to use. I will show you the best ways to enter dates and times, including some great shortcuts, how to quickly build date time series, apply date time formatting instantly, and when necessary, create your own custom date formats for optimum readability.

We'll see powerful date functions that determine a day of the week, calculate the number of working days between two dates, and determine future and past target dates. I will also show you the powerful but poorly documented datedif function. We'll look at shortcuts and tips to optimize tricky time calculations and the best techniques for converting dates downloaded from other sources, how to use dates in data validation rules, as well as in filtering. But enough talk. Let's start saving time with Excel 2007.
