Need to figure out the best time for a conference call across time zones? Want to count the days between two dates? TimeAndDate.com is one of those all-in-one web tools that people often seem to forget about, but its recent redesign and new time zone map means it deserves another look.
Google and Wolfram Alpha can perform some of TimeAndDate.com's functions through relatively quick searches, but this dashboard-style site gives you many more options and inter-linked tools. You can plan your travel itinerary, get up to speed with the time, currency and weather when you arrive, set up day-to-day countdowns and lots more. It's a must-have bookmark and a potentially awesome replacement for widgets or system utilities with limited functionality.
