Time functions in Excel

Using time functions in Excel you can calculate, for example, how many hours or minutes an employee spent on a task or how many hours and minutes it took for the chemical reaction to complete. If you are diabetic and taking insulin injections, you can see how your sugar level is controlled over time.

• Microsoft Excel recognizes information as time if hours, minute and seconds are separated by colons. Example: 8:30:05 AM
• Times are stored in Excel as decimal numbers. Midnight 12:00 AM is 0 and noon 12:00 PM is stored as 0.5
• You must enter a or p after the time or Excel assumes it is AM
