Spreadsheet Tool: "What Time Do I Need Leave?"

This is a nifty little spreadsheet tool that I made because I commonly found myself calculating what time I needed to leave the house by if I wanted to make it somewhere on time.

On the left you input:

• What time you need to arrive.
• All the stop/errands you need to make along the way and the time they will take.

On the right, you'll get:

• The total time your stops/errands will take
• What time you need to leave in order to arrive on time.

The spread sheet runs in MS Office or OpenOffice. You can download it here:
