Do you work with colleagues scattered around the country or the world, or need to communicate with friends and family at an acceptable hour for all?
Then check out this website:
You select up to four cities, then the online software tries to find a convenient time for everyone. A colour-coded table of times shows you which are the best times.

Update: Microsoft has a small Time Zone program you can download and install. You enter the locations and when you hover over the icon in the System Tray, the places and their current days and times are displayed. I find it very handy as my main client is in Brisbane, one of my client’s bosses is in Sydney, and I have a regular conference call with people in Auckland and Boston (NY time).
